Farm Process

Number of farm well parameters (changeable parameter is a multiplier of the maximum capacity).

Maximum number of parameter farm wells.

Flag indicating the automatic use of parent parameter farm-well list entries for the child model (if ILGR>0 and for child model grids where IGRID>1) (only character “P” or blank possible).

If MXLP is set to P after MXL, then the maximum number of parent model parameter farm-well list entries may be used as child model parameter farm wells in well locations, where the child model farm ID coincides with the parent model farm ID. IF MXLP=P, then the maximum number of parent model parameter farm-well list entries as specified for the parent model (MXL of parent model) is added to the maximum number of parameter wells list entries specified in the child model, MXL, to allocate space for parameter farm-wells list entries specified in the child model AND pulled from the parent model. If only the use of parent model parameter wells for a child model is desired, and no child model specific parameter farm wells exist, MXL still needs to be specified as zero. If only the use of child model parameter wells is desired, and no parent model parameter farm wells are to be pulled from the parent mode, then MXLP is omitted.

Maximum number of active farm wells including parameter and nonparameter farm wells. Nonparameter farm wells are wells, whose maximum capacity is different for each stress period. In this case, each well-list (layer, location, farm-well farm ID, maximum capacity) would have to be read for each stress period. However, since the maximum capacity in most cases is thought to be constant for the entire simulation, usually the maximum number of nonparameter farm wells will be zero, that is, MXL = MXACTFW.

Flag indicating the automatic use of parent nonparameter farm-well list entries for the child model (if ILGR>0 and for child model grids where IGRID>1) (only character “P” or blank possible).

If MXACTFWP is set to P after MXACTFW, then the maximum number of parent model nonparameter farm-well list entries may be used as child model nonparameter farm wells in well locations where the child model farm ID coincides with the parent model farm ID. If MXACTFWP =P, then the maximum number of parent model nonparameter farm-well list entries specified for the parent model (MXACTFW of parent model) is added to the maximum of nonparameter wells list entries specified in the child model, MXACTFW, to allocate space for nonparameter farm-wells list entries specified in the child model AND pulled from the parent model. If only the use of parent model nonparameter wells for a child model is desired, and no child model specific nonparameter farm wells exist, MXACTFW still needs to be specified as zero. If only the use of child model nonparameter wells is desired, and no parent model nonparameter farm wells are to be pulled from the parent model, then MXACTFWP is omitted.

Maximum number of water-balance subregions (farms) specified during the entire simulation.

Number of crop types.

Number of soil types.

1 = Farms (IFID(IC, IR)) specified for the entire simulation. (Data Set 6)

2 = Farms (IFID(IC, IR)) specified for each stress period. (Data Set 26)

P = Farms in child model are specified the same way as in the parent model.

Root depth flag (1,2,3, "P" possible)

P = Root depths specified or calculated for the parent model (as defined by the parent model’s IRTFL entry) are automatically used for crop IDs present in the child model. No additional crop-specific root depth list entries (for parent IRTFL=1, 2, 3) or climate data time series (for parent IRTFL=3) are necessary.

Consumptive-use flag (-1, 1, 2, 3, “P” possible)

•3 = FMP3 calculates a daily potential crop evapotranspiration flux (ETc-pot) by multiplying a daily reference evapotranspiration flux (ETref) read as time series for the entire simulation in Item 16 with a daily crop coefficient Kc derived from parameters read for the entire simulation as Item 15 (ETc-pot = Kc*ETref). FMP3 multiplies a daily ETc-pot averaged over each time step by the area of each cropped cell (ICID(IC,IR > 0) to yield a cell-by-cell ETc-pot flow rate for each time step. FMP3 multiplies the daily ETref flux averaged over each time step by the area of each fallow cell (ICID(IC,IR) = –1) to yield a cell-by-cell ETref flow rate for each time step. The ETref is assumed to be 100% evaporative for fallow cells where no transpiration exists.

•2 = A list of crop specific fluxes of potential crop evapotranspiration (ETc-pot) is read as Item 30a (Crop-ID, ETc-pot flux) for every stress period. FMP3 multiplies this ETc-pot flux by the area of the each cropped cell (ICID(IC,IR) > 0) to yield a cell-by-cell ETc-pot flow rate for each stress period. FMP3’s fallow-cell option (ICID(IC,IR) = –1) cannot be used because no ETref flux is read if ICUFL = 2.

•1 = A list of crop specific fluxes of potential crop evapotranspiration (ETc-pot) is read as Item 30a (Crop-ID, ETc-pot flux) for every stress period and a constant or 2D real array reference evapotranspiration ETref (NCOL,NROW) is read as Item 30b for every stress period. FMP3 multiplies the ETc-pot flux by the area of the cropped cell (ICID(IC,IR) > 0) to yield a cell-by-cell ETc-pot flow rate for each stress period. FMP3 multiplies the ETref flux by the area of each fallow cell (ICID(IC,IR) = –1) to yield a cell-by-cell ETref flow rate for each stress period. The ETref is assumed to be 100% evaporative for fallow cells where no transpiration exists.

•-1 = A list of crop specific crop coefficients (Kc) is read as Item 30a (Crop-ID, Kc) for every stress period and a constant or 2D real array of reference evapotranspiration ETref (NCOL,NROW) is read as Item 30b for every stress period. FMP3 multiplies the Kc by the ETref flux and by the area of each cropped cell (ICID(IC,IR) > 0) to yield a cell-by-cell ETc-pot flow rate for each stress period. FMP3 multiplies the ETref flux by the area of each fallow cell (ICID(IC,IR) = –1) to yield a cell-by-cell ETref flow rate for each stress period. The ETref is assumed to be 100% evaporative for fallow cells where no transpiration exists.

•P = Potential crop-evapotranspiration flux (ETc-pot) or crop coefficients (Kc) specified or calculated for parent model (as defined by the parent model’s ICUFL entry) are automatically used for crop IDs present in child model. No additional crop-specific ETc-pot list entries (for parent ICUFL=1,2), Kc, list entries (for parent ICUFL=-1), reference ET arrays (for parent ICUFL=-1,1), or crop-specific growing degree coefficients and climate data time series (for parent ICUFL=3) are necessary. For parent ICUFL=–1,1, the child-model reference evapotranspiration at the child-model grid resolution is automatically derived from the parent-model reference evapotranspiration by bilinear interpolation.

•2 = Precipitation flux specified for the each stress period (Data Set 33)

•3 = Precipitation flux calculated as average for each time step from daily time series of precipitation flux specified in climate-data time series read in Item 16 for the entire simulation.

•P = Precipitation flux specified or calculated for the parent model (as defined by the parent model’s IPFL entry) is automatically used for the child model. No additional precipitation-flux array (for parent IPFL=2) or time-series (for parent IPFL=3) data sets are necessary. For parent IPFL=2, the child-model precipitation-flux array at the child-model grid resolution is automatically derived from the parent-model array by bilinear interpolation.

Fraction-of-transpiration-and-evaporation-of-crop-consumptive-use flag (1, 2, “P” possible)

•1 = Transpiratory and evaporative fractions of consumptive use specified for the entire simulation (Data Set 12).

•2 = Transpiratory and evaporative fractions of consumptive use specified for each stress period (Data Set 31).

•P = Transpiratory and evaporative fractions of consumptive use specified for the parent model (as defined by the parent model’s IFTEFL entry) are automatically used for the child model. No additional crop-specific FTR, FEP, or FEI list entries are necessary.

Fraction-of-inefficiency-losses-to-SW-runoff flag (0, 1, 2, “P” possible)

•0 = The fraction of inefficiency losses to surface-water runoff is proportional to the slope of ground surface. The slope is estimated by FMP by a third order finite difference method using all eight outer points of the 3 ×3 kernel surrounding the cell. At cells directly adjacent to the boundary or the corners of the grid domain, the slope is calculated by using a 2 × 3 or 2 × 2 kernel, respectively. There is no data input required for FIESWP and FIESWI if IIESWFL is zero.

•1 = Fractions of in-efficient losses to surface-water runoff related to precipitation and irrigation specified for the entire simulation (Data Set 13).

•2 = Fractions of in-efficient losses to surface-water runoff related to precipitation and irrigation specified for each stress period (Data Set 32).

•P = Fraction of inefficiency losses to surface-water runoff specified for the parent model (as defined by the parent model’s IIESWFL entry) are automatically used for the child model. No additional crop-specific FIESWP or FIESWI list entries are necessary. For parent IESWFL=0, the slope of child-model cells is calculated as described above on the basis of a ground surface-elevation array either derived automatically the parent elevation by bilinear interpolation (GSURF=P) or on a child-model specific elevation array.

Efficiency Flag (1, 2, “P” possible)

1 = On-farm efficiency either as OFE(Farm-ID) per farm or as OFE(Farm-ID, Crop-IDNCROPS) per farm and per crop specified for the entire simulation (Data Set 7).

•0 = Conservative Behavior – Cell-by-cell efficiency is held constant over time step with respect to changing groundwater level. Farm efficiency reset to specified efficiency at each stress period.

•1 = Conservative Behavior – Cell -by-cell efficiency is held constant over time with respect to changing groundwater level. Farm efficiency reset to specified efficiency at each time step.

For IEBFL = 2,3: Cell-by-cell efficiency varies with changing groundwater level, but cell-by-cell delivery does not vary with changing groundwater level. However, farm delivery may vary in response to deficit irrigation (if IDEFFL = –1).

•2 = Conservative Behavior – Cell-by-cell delivery is held constant over time step with respect to changing groundwater level (evaluation of initial total delivery requirement (TDR) per cell at first iteration of first time step of each stress period). Farm efficiency reset to specified efficiency at each stress period.

•3 = Conservative Behavior – Cell-by-cell delivery is held constant over time step with respect to changing groundwater level (evaluation of initial total delivery requirement (TDR) per cell at first iteration of each time step). Farm efficiency reset to specified efficiency at each time step.

Crop rotation flag:

•2 = Acreage-Optimization with Water Conservation Pool (only if SFR is specified in Name File, if a diversion from a river segment into a diversion-segment is specified in the SFR input file, and if routed or semi-routed deliveries from such a diversion-segment into farms can occur (IRDFL = 1, -1 or ISRDFL = 1, 2). (See Data Sets 18, 19, 34 and 35.)

•3 = Acreage-Optimization (a-priori) (Undocumented and incomplete.)

•4 = Acreage-Optimization with Water Conservation Pool (a-priori) (Undocumented and incomplete.)

2 = Groundwater Allotments (ALLOTGW(NF)) specified for each stress period. (See Data Set 25.)

P = use parent-model groundwater allotments and bypass reading ALLOTGW per simulation or stress period. For child IALLOTGW=P and parent IALLOTGW=1, no additional data are required for the child model.

Concept used for the approximation of ET-fluxes with changing head:

•1 for consumptive use Concept 1 = plant-and soil-specific pseudo steady state transpiration approximated by analytical solution: A restriction of active root zone corresponding to anoxia- or wilting-related pressure heads is determined by FMP by using analytical solutions of a vertical pseudo steady state pressure head distribution over the depth of the total root zone. (FMP3 not linked to UZF1). (See data sets 9 and 14.)

•2 for consumptive use Concept 2 = nonplant- and nonsoil-specific simplification of Concept 1. (FMP3 not linked to UZF1).

•3 for consumptive use Concept 1 = plant-and soil-specific pseudo steady state transpiration approximated by analytical solution: A restriction of active root zone corresponding to anoxia- or wilting-related pressure heads is determined by FMP by using analytical solutions of a vertical pseudo steady state pressure head distribution over the depth of the total root zone. (FMP3 linked to UZF1: FMP3 farm identification arrays linked to coinciding UZF1 infiltration arrays). (See data sets 9 and 14.)

•4 for consumptive use Concept 2 = nonplant- and nonsoil-specific simplification of Concept 1. (FMP3 linked to UZF1: FMP3 farm identification arrays linked to coinciding UZF1 infiltration arrays).

•P = Consumptive use Concept specified in parent model is used for child model. For child ICCFL=P and parent ICCFL=1, no additional data are required for crop-specific PSI list entries for the child model.

Non-Routed Surface-Water Delivery Flag: (0, 1, “P” possible) :

•0 = no Non-Routed Surface-Water Delivery (NRD) exists.

•1 = NRDs exist. A farm related list of Volumes, Ranks, and Use-Flags of NRD will be read. (Data Set 36)

•P = A farm related list of Volumes, Ranks, and Use-Flags of NRDs for the parent model (as specified by the initial parent model’s INRDFL entry) is automatically used for the child model. No additional list entries for the child model are necessary. INRDFL=P allows the scaling of ranked NRDs to parent or child model farm by the ratio between the residual parent or child farm demand and the joint residual parent plus child demand. For IGRID=1, the ranked NRDs to the residual parent model farm are scaled by the ratio (residual parent farm demand/joint residual parent+child farm demand). For IGRID>1, the ranked NRDs to the child model farm are scaled by the ratio (child farm demand/joint residual parent+child farm demand) and adopt NRD-Ranks and NRD-Use flag setting from the parent model NRD data input.

(Limitation: not allowed for WELLFIELD option).

Maximum number of non-routed delivery types (read if INRDFL = 1, if ILRG=0, or if ILGR>0, and for parent model grids where IGRID=1, or if ILGR>0, and for child model grids where IGRID>1 and INRDFL=1). MXNRDT is omitted if ILGR>0 and for child model grids where IGRID>1 and INRDFL=P. In this case, memory for NRD related attributes is allocated by twice the number of parent-MXNRDT to save old RNDRs for each type before scaling it down as a result of prorating for parent and child farm NRDs. (See Data Set 33)

Semi-Routed Surface-Water Delivery Flag:

•0 = no Semi-Routed Surface-Water Delivery exists

•1 or 2 = Semi-Routed Surface-Water Deliveries exist. (Routing surface-water along a river or major canal, and allocating non-routed deliveries from a point of diversion). A farm related list of Row- and Column-coordinates or segment and reach numbers for a point of diversion will be read (only if SFR or SWR1 is specified in Name File). An additional flag for each.

•1 = List of Row- and Column-coordinates or segment and reach numbers for SFR is read for the entire simulation. (See Data Set 21a.)

•2 = List of Row- and Column-coordinates or segment and reach numbers for SFR is read for each stress period. (See Data Set 37a.)

For a parent model farm (IGRID=1) with a head-gate (SFR in Name File), for a child model farm without any stream network (IGRID>1; SFR not in Name File), and where a residual parent farm and child farm have equal farm ID:

•P = A point of diversion along the stream network defined for the parent model by row and column coordinates or segment and reach number (as defined by the parent model’s ISRDFL settting) is also used to receive the residual demand of child model farm in addition to the residual demand of parent model farm. No additional farm-specific SRD list entries are required for the child model.

The child model farm without a head-gate reach does not have any actual farm delivery from surface water from an own source, but may receive deliveries from the parent farm head gate subject to availability. Parent and child farms may either receive actual surface-water deliveries in full or at a reduced rate depending on whether their cumulative demand is less or more than the available supply:

•If the sum of residual demands of parent and child model farms exceeds any supply constraints, such as the available streamflow or surface-water allotment in the parent model head-gate reach, then

•the entire constraint will be diverted from the streamflow available at the parent farm’s head-gate reach, and

•the residual delivery requirement of both farms will be reduced to the respective constraint. This is accomplished by scaling the delivery requirement of the residual parent or child farm farm by the ratio [constraint/(parent farm demand + sum of demands of all child model farms)]. The reduced demand will be passed on to the farm budget.

•If the sum of residual demands of parent and child model farms does not exceed any supply constraints, then

•the child farm demand, in addition to parent farm demand, is diverted from the streamflow available at the parent farm’s head-gate reach, and

•the residual delivery requirement of both farms will by supplied in full and passed on to the farm budget.

Routed Surface-Water Delivery Flag (0, 1, –1, “P” possible):

•0 = no surface-water delivery exists.

•1 = fully-routed surface-water delivery may occur from the uppermost reach of a series of diversion-segment reaches located within a farm. Caution: Streamflow fully-routed through a conveyance network directly to a farm can only occur (1) if SFR is specified in Name File, (2) if at least one reach of a diversion segment is located within the farms, and (3) if streamflow is available.

•–1 = fully-routed surface-water delivery may occur from the uppermost reach of a series of reaches of any type of stream segment located within a farm. Caution: Streamflow fully-routed through a conveyance network directly to a farm can only occur (1) if SFR is specified in Name File, (2) if at least one reach of a any type of segment is located within the farms, and (3) if streamflow is available.

•P = The IRDFL flag setting defined for the parent model will be applied. Fully routed surface-water delivieries within a child model are subject to SFR being specified in the child model Name File and the existence of a respective segment (diversion segment for IRDFL=1; any type of segment for IRDFL=-1).

Semi-Routed Surface-Water Runoff Return Flow Flag (0, 1, 2, “P” possible):

•0 = No locations along the stream network are specified for any farm, where semi-routed runoff return flow is recharged into the stream network. Runoff is either automatically prorated over non-diversion-segment reaches located within a farm, or automatically recharged into one non-diversion-segment reach nearest to the lowest elevation of the farm.

•1 or 2 = For each farm, a location is specified anywhere along the stream network, where semi-routed runoff return flow is recharged anywhere in the active model domain. A farm-related list of row and column coordinates or segment and reach numbers for a point of runoff return flow recharge will be read (only if SFR is specified in Name File).

•1 = List of row and column coordinates or segment and reach numbers and target of Semi-routed Delivery to SFR or indirectly to SWR through an SFR segment is read for the entire simulation. (See Data Set 21b.)

•2 = List of row and column coordinates or segment and reach numbers and target of Semi-routed Delivery to SFR or indirectly to SWR through an SFR segment is read for each stress period. (See Data Set 37b.)

For a parent model farm (IGRID=1) with a head-gate (SFR in Name File), for a child model farm without any stream network (IGRID>1; SFR not in Name File), and where a residual parent farm and child farm have equal farm ID:

•P = A point of return flow recharge along the stream network for the parent model by row and column coordinates or segment and reach number (as defined by the parent model’s ISRRFL setting) is also used to receive the cumulative runoff return flow of the child model farm in addition the return flow of the parent-model farm. If the parent ISRRFL ≥ 1 and zero coordinates are specified for the return flow location of a parent farm, then the return flow from the child model is added to “automatic fully routed runoff return flow” prorated over drain segments found within the parent model farm or to “automatic semi-routed runoff return flow” discharged into a reach remote from the parent farm, but nearest to the lowest elevation of the parent farm. No additional farm-specific SRR list entries are required for the child model.

The absence of a SFR network within the child model domain does not allow the child farm to return runoff to any specified our automatically detected reaches. However, the child farm may return runoff to the parent farm’s return flow reaches, which may be specified or automatically detected as reaches within the farm domain or as a remote reach nearest to the lowest elevation of the parent farm.

Routed Surface-Water Runoff Return Flow Flag (0, 1, –1, “P” possible):

•0 = no surface-water runoff return flow possible (no SFR specified in Name File).

•1 = surface-water runoff may be returned as fully-routed return flow to a series of non-diversion-segment reaches located within a farm (prorated over each reach weighted by the reach length). Caution: Fully-routed return flow directly from a farm to a series of non-diversion-segment reaches can only occur (1) if SFR is specified in Name File and (2) if at least one reach of a non-diversion segment is located within the farm. Also, it occurs if segment and reach of farm in the SRD input file are set to 0.

•–1 = fully surface-water runoff may be returned as fully-routed return flow to a series of reaches of any segment of stream type located within a farm (prorated over each reach weighted by the reach length). Caution: Fully-routed return flow directly from a farm to a series of reaches of any type of stream segment can only occur (1) if SFR is specified in Name File and (2) if at least one reach of a non-diversion segment is located within the farm. Also, it occurs if the segment and reach of farm in the SRD input file are set to 0.

•P = The IRRFL flag setting defined for the parent model will be applied. Fully routed surface-water runoff return flow within a child model are subject to SFR being specified in the child model Name File and the existence of a respective segment (return flow to non-diversion segment for IRRFL=1; return flow to any type of segment for IRDFL=-1).

Surface-water allotment flag

(IALLOTSW > 1 not yet tested for parent model farm (IGRID=1) and child model farm (IGRID>1) straddling the parent/child model boundary and with equal farm ID):

0–No surface-water allotment specified,

1–Equally appropriated surface-water allotment height [L] specified per stress period (specification of diversions from a river into diversion segments in SFR input file required if ISRDFL = 1 or 2, or IRDFL = 1). (See Data Set 38.)

2–Prior appropriation system with Water Rights Calls [L3/T] (diversion rates from a river into diversion segments are simulated based on estimate of TFDR if ISRDFL = 1 or 2, or IRDFL = 1; specification of a farm-specific water rights calls list required for each stress period). (See Data Set 39.)

3–Prior appropriation system without Water Rights Calls [L3/T] (diversion rates from a river into diversion segments are simulated if ISRDFL = 1 or 2, or IRDFL = 1).

For a parent model farm (IGRID=1) and child model farm(s) (IGRID>1) and where a residual parent farm and child farm have equal farm ID:

P = use parent model equal appropriation allotment heights and bypass reading ALLOTSW per stress period. For child IALLOTSW=P and parent IALLOTSW=1, no additional data are required for the child model.

Allotment rates for the residual parent farm and the child farms are calculated on the basis of each area. Each child farm allotment rate is then added to the residual parent farm allotment rate. This joint allotment rate is then used to constrain the available streamflow in head-gate, from which water is diverted that accounts for the residual demands of the parent and child farms.

User specified closure criterion for simulated diversions into diversion segments if prior appropriation is chosen [L3/T] (only to specify if IALLOTSW> 1)

Optional routing information print flag if the SFR Package is specified in the Name file. If the model is as child model, IRTPFL is required if the SFR Package is specified in the Name file of either the parent or child model.

Information regarding the routing of farm deliveries and farm runoff return flows will be written either to the listing file or to a separate ASCII file, called ROUT.OUT.

The information regarding deliveries tells whether the farm can potentially receive either:

(a) fully-routed deliveries from the first, most upstream located reach of a sequence of automatically detected delivery-segment reaches within a farm, or whether

(b) the farm can potentially receive semi-routed deliveries from specified stream reaches.

The information regarding return flows tells whether potential runoff from the farm is returned either

(a) full-routed to automatically detected return flow-segment reaches within a farm, over which the runoff return flow is prorated, weighted by the length of each reach, or

(b) semi-routed to specified stream reaches, or in lack of this first two options,

(c) semi-routed to automatically detected return flow-segment reach nearest to the lowest elevation of a farm.

Indicates that no optional flags for auxiliary variables are specified. NOAUX is only required if Flag Blocks are used. If flags are read in Item 2b from a single line (as before in FMP1), then no entry is required if no optional flags for auxiliary variables are specified.

AUX “abc” Defines an auxiliary variable, “abc”, which will be read for each farm-well as part of Items 4 and 23. Up to five auxiliary attributes “abc” can optionally be specified, each of which must be preceded by “AUX.” These values will be read after the QMAXfact or QMAX variable of Item 4 or Item 23, respectively.

AUX QMAXRESET The specification of the optional flag “AUX QMAXRESET” for {option} in Item 2 will prompt FMP to reset QMAX as simulated by the MNW Package to the default QMAX as defined by FMP at the beginning of each time step. The optional flag “AUX QMAXRESET” requires FMP to read an auxiliary variable after the QMAXfact or QMAX variable of the farm wells list in Items 4 or 23, or after any other preceding auxiliary variable (e.g., AUX NOCIRNOQ). If a “1” is read, then the MNW-simulated QMAX is reset to the default QMAX in the first iteration of each time step.

AUX NOCIRNOQ The specification of the optional flag “AUX NOCIRNOQ” for {option} in Item 2 will prompt FMP to limit the distribution of farm pumpage to farm wells, whose row and column coincides with a top layer cell with a current irrigation requirement from active crops. “NOCIRNOQ” stands for “no crop irrigation requirement (CIR), no pumping (Q).” The optional flag “AUX NOCIRNOQ” requires FMP to read an auxiliary variable after the QMAXfact or QMAX variable of the farm wells list in Item 4 or 23, or after any other preceding auxiliary variable (e.g. AUX QMAXRESET). The auxiliary variable for “AUX NOCIRNOQ” is defined to be a binary parameter that tells which wells are selected for the NOCIRNOQ option. If a “1” is read, then the respective well is selected for setting its maximum capacity to zero if, during a particular time step, no crop irrigation requirement of the top layer cell exists. At each new time step the maximum capacity of such a select well will be reset to the default value.

Identifies a child model grid with respect to a parent model for FMP transfer of properties.

NOOPT Indicates that no Options are specified. NOOPT is only required if Flag Blocks are used. If flags are read in Item 2b from a single line (as before in FMP1), then no entry is required if no Options are specified.

CBC Indicates that memory should be allocated to store cell-by-cell flow for each well to make these flows available for use in other process.

NOPRINT Indicates that a list of specified farm well attributes will not be printed to the list file.

WELLFIELD Allows a series of irrigated farms to receive their cumulative irrigation demand as simulated non-routed deliveries from well fields simulated as virtual farms. A virtual well-field farm with one or several wells (well fields) receives a cumulative pumping requirement equal to the cumulative irrigation delivery requirement of irrigated farms that are supplied by the well field. If the cumulative demand exceeds the cumulative maximum pumping capacity of the well field, then other well field can supply the residual demand. The cumulative pumpage of the well field that is equal or less than the desired demand will then be re-distributed to the farms supplied by the well field weighted by the total delivery requirement (or residual delivery requirement for lower priority well fields) of the receiving farms. FMP3 then applies this re-distributed rate as non-routed deliveries to the respective farms.

For farms that receive water from a particular well field, in Item 36, the non-routed delivery volume may be set to a dummy zero, as the non-routed delivery is simulated by the well-field option. The rank of the non-routed delivery, NRDR, must consistently be equal to the priority of the well-field. The NRDU flag has to be set to “minus the Farm ID of the virtual farm that contains the well field” for the farms receiving water from the respective well field. For the virtual well-field farm itself, the NRDU flag has to be set to one.

For first priority well field and farms receiving water from that well field:

NRDVt1(NFARMS) = 0 (dummy zero: simulated when option WELLFIELD is set)

NRDRt1(NFARMS) = 1 (Type 1 must be of rank 1 for well-field farm and for receiving farms)

NRDUt1(FIDrec-wf-1) = negative value of Farm-ID of virtual well-field farm

NRDUt1(FIDwf-1) = 1

NRDUt1(FIDother) = 0

For second priority well field and farms receiving water from that well field:

NRDVt2(NFARMS) = 0 (dummy zero: simulated when option WELLFIELD is set)

NRDRt2(NFARMS) = 2 (Type 2 must be of rank 2 for well-field farm and for receiving farms)

NRDUt2(FIDrec-wf-2) = negative value of Farm-ID of virtual well-field farm

NRDUt2(FIDwf-2) = 1

NRDUt2(FIDother) = 0

For a well field of priority n and farms receiving water from that well field:

NRDVtn(NFARMS) = 0 (dummy zero: simulated when option WELLFIELD is set)

NRDRtn(NFARMS) = n (Type n must be of rank n for well-field farm and for receiving farms)

NRDUtn(FIDrec-wf-n) = negative value of Farm-ID of virtual well-field farm

NRDUtn(FIDwf-n) = 1

NRDUtn(FIDother) = 0

NRDV, NRDR, NRDU definitions see “Non-Routed Surface-Water Deliveries” below

FIDrec-wf-n = Farm-ID of a farm receiving water from well-field n;

FIDwf-n = Farm-ID of a virtual well-field farm n.

The non-routed delivery type that originates from the lowest priority well field cannot be higher than the maximum number of non-routed delivery types, MXNRDT.

RECOMP_Q_BD Re-computation of the Farm Process FM-routine is invoked at the end each time step loop.

MNWCLOSE Head- and residual-closure criteria of the MODFLOW solver Package will be adjusted to allow convergence of the FMP pumping requirement to pumping simulated by the linked MNW1 or MNW2 packages.

Criterion for actual MNW pumping rate to converge to FMP pumping requirement (real number)

Fraction of reduction of head-change closure criterion if QCLOSE was not met [ ].

Fraction of reduction of residual-change closure criterion if QCLOSE was not met [ ].

Maximum number of active farm wells including parameter and nonparameter farm wells. Nonparameter farm wells are wells, whose maximum capacity is different for each stress period. In this case, each well-list (layer, location, farm-well farm ID, maximum capacity) would have to be read for each stress period. However, since the maximum capacity in most cases is thought to be constant for the entire simulation, usually the maximum number of nonparameter farm wells will be zero, that is, MXL = MXACTFW.

Flag indicating the automatic use of parent nonparameter farm-well list entries for the child model (if ILGR>0 and for child model grids where IGRID>1) (only character “P” or blank possible).

If MXACTFWP is set to P after MXACTFW, then the maximum number of parent model nonparameter farm-well list entries may be used as child model nonparameter farm wells in well locations where the child model farm ID coincides with the parent model farm ID. If MXACTFWP =P, then the maximum number of parent model nonparameter farm-well list entries specified for the parent model (MXACTFW of parent model) is added to the maximum of nonparameter wells list entries specified in the child model, MXACTFW, to allocate space for nonparameter farm-wells list entries specified in the child model AND pulled from the parent model. If only the use of parent model nonparameter wells for a child model is desired, and no child model specific nonparameter farm wells exist, MXACTFW still needs to be specified as zero. If only the use of child model nonparameter wells is desired, and no parent model nonparameter farm wells are to be pulled from the parent model, then MXACTFWP is omitted.

Maximum number of water-balance subregions (farms) specified during the entire simulation.

Number of crop types.

P = Root depths specified or calculated for the parent model (as defined by the parent model’s IRTFL entry) are automatically used for crop IDs present in the child model. No additional crop-specific root depth list entries (for parent IRTFL=1, 2, 3) or climate data time series (for parent IRTFL=3) are necessary.

Consumptive-use flag (-1, 1, 2, 3, “P” possible)

•3 = FMP3 calculates a daily potential crop evapotranspiration flux (ETc-pot) by multiplying a daily reference evapotranspiration flux (ETref) read as time series for the entire simulation in Item 16 with a daily crop coefficient Kc derived from parameters read for the entire simulation as Item 15 (ETc-pot = Kc*ETref). FMP3 multiplies a daily ETc-pot averaged over each time step by the area of each cropped cell (ICID(IC,IR > 0) to yield a cell-by-cell ETc-pot flow rate for each time step. FMP3 multiplies the daily ETref flux averaged over each time step by the area of each fallow cell (ICID(IC,IR) = –1) to yield a cell-by-cell ETref flow rate for each time step. The ETref is assumed to be 100% evaporative for fallow cells where no transpiration exists.

•2 = A list of crop specific fluxes of potential crop evapotranspiration (ETc-pot) is read as Item 30a (Crop-ID, ETc-pot flux) for every stress period. FMP3 multiplies this ETc-pot flux by the area of the each cropped cell (ICID(IC,IR) > 0) to yield a cell-by-cell ETc-pot flow rate for each stress period. FMP3’s fallow-cell option (ICID(IC,IR) = –1) cannot be used because no ETref flux is read if ICUFL = 2.

•1 = A list of crop specific fluxes of potential crop evapotranspiration (ETc-pot) is read as Item 30a (Crop-ID, ETc-pot flux) for every stress period and a constant or 2D real array reference evapotranspiration ETref (NCOL,NROW) is read as Item 30b for every stress period. FMP3 multiplies the ETc-pot flux by the area of the cropped cell (ICID(IC,IR) > 0) to yield a cell-by-cell ETc-pot flow rate for each stress period. FMP3 multiplies the ETref flux by the area of each fallow cell (ICID(IC,IR) = –1) to yield a cell-by-cell ETref flow rate for each stress period. The ETref is assumed to be 100% evaporative for fallow cells where no transpiration exists.

•-1 = A list of crop specific crop coefficients (Kc) is read as Item 30a (Crop-ID, Kc) for every stress period and a constant or 2D real array of reference evapotranspiration ETref (NCOL,NROW) is read as Item 30b for every stress period. FMP3 multiplies the Kc by the ETref flux and by the area of each cropped cell (ICID(IC,IR) > 0) to yield a cell-by-cell ETc-pot flow rate for each stress period. FMP3 multiplies the ETref flux by the area of each fallow cell (ICID(IC,IR) = –1) to yield a cell-by-cell ETref flow rate for each stress period. The ETref is assumed to be 100% evaporative for fallow cells where no transpiration exists.

•P = Potential crop-evapotranspiration flux (ETc-pot) or crop coefficients (Kc) specified or calculated for parent model (as defined by the parent model’s ICUFL entry) are automatically used for crop IDs present in child model. No additional crop-specific ETc-pot list entries (for parent ICUFL=1,2), Kc, list entries (for parent ICUFL=-1), reference ET arrays (for parent ICUFL=-1,1), or crop-specific growing degree coefficients and climate data time series (for parent ICUFL=3) are necessary. For parent ICUFL=–1,1, the child-model reference evapotranspiration at the child-model grid resolution is automatically derived from the parent-model reference evapotranspiration by bilinear interpolation.

•2 = Precipitation flux specified for the each stress period (Data Set 33)

•3 = Precipitation flux calculated as average for each time step from daily time series of precipitation flux specified in climate-data time series read in Item 16 for the entire simulation.

•P = Precipitation flux specified or calculated for the parent model (as defined by the parent model’s IPFL entry) is automatically used for the child model. No additional precipitation-flux array (for parent IPFL=2) or time-series (for parent IPFL=3) data sets are necessary. For parent IPFL=2, the child-model precipitation-flux array at the child-model grid resolution is automatically derived from the parent-model array by bilinear interpolation.

Fraction-of-transpiration-and-evaporation-of-crop-consumptive-use flag (1, 2, “P” possible)

•2 = Transpiratory and evaporative fractions of consumptive use specified for each stress period (Data Set 31).

•P = Transpiratory and evaporative fractions of consumptive use specified for the parent model (as defined by the parent model’s IFTEFL entry) are automatically used for the child model. No additional crop-specific FTR, FEP, or FEI list entries are necessary.

Fraction-of-inefficiency-losses-to-SW-runoff flag (0, 1, 2, “P” possible)

•0 = The fraction of inefficiency losses to surface-water runoff is proportional to the slope of ground surface. The slope is estimated by FMP by a third order finite difference method using all eight outer points of the 3 ×3 kernel surrounding the cell. At cells directly adjacent to the boundary or the corners of the grid domain, the slope is calculated by using a 2 × 3 or 2 × 2 kernel, respectively. There is no data input required for FIESWP and FIESWI if IIESWFL is zero.

•1 = Fractions of in-efficient losses to surface-water runoff related to precipitation and irrigation specified for the entire simulation (Data Set 13).

•2 = Fractions of in-efficient losses to surface-water runoff related to precipitation and irrigation specified for each stress period (Data Set 32).

•P = Fraction of inefficiency losses to surface-water runoff specified for the parent model (as defined by the parent model’s IIESWFL entry) are automatically used for the child model. No additional crop-specific FIESWP or FIESWI list entries are necessary. For parent IESWFL=0, the slope of child-model cells is calculated as described above on the basis of a ground surface-elevation array either derived automatically the parent elevation by bilinear interpolation (GSURF=P) or on a child-model specific elevation array.

Efficiency Flag (1, 2, “P” possible)

•2 = Acreage-Optimization with Water Conservation Pool (only if SFR is specified in Name File, if a diversion from a river segment into a diversion-segment is specified in the SFR input file, and if routed or semi-routed deliveries from such a diversion-segment into farms can occur (IRDFL = 1, -1 or ISRDFL = 1, 2). (See Data Sets 18, 19, 34 and 35.)

•3 = Acreage-Optimization (a-priori) (Undocumented and incomplete.)

•4 = Acreage-Optimization with Water Conservation Pool (a-priori) (Undocumented and incomplete.)

Concept used for the approximation of ET-fluxes with changing head:

•1 for consumptive use Concept 1 = plant-and soil-specific pseudo steady state transpiration approximated by analytical solution: A restriction of active root zone corresponding to anoxia- or wilting-related pressure heads is determined by FMP by using analytical solutions of a vertical pseudo steady state pressure head distribution over the depth of the total root zone. (FMP3 not linked to UZF1). (See data sets 9 and 14.)

•2 for consumptive use Concept 2 = nonplant- and nonsoil-specific simplification of Concept 1. (FMP3 not linked to UZF1).

•3 for consumptive use Concept 1 = plant-and soil-specific pseudo steady state transpiration approximated by analytical solution: A restriction of active root zone corresponding to anoxia- or wilting-related pressure heads is determined by FMP by using analytical solutions of a vertical pseudo steady state pressure head distribution over the depth of the total root zone. (FMP3 linked to UZF1: FMP3 farm identification arrays linked to coinciding UZF1 infiltration arrays). (See data sets 9 and 14.)

•P = A farm related list of Volumes, Ranks, and Use-Flags of NRDs for the parent model (as specified by the initial parent model’s INRDFL entry) is automatically used for the child model. No additional list entries for the child model are necessary. INRDFL=P allows the scaling of ranked NRDs to parent or child model farm by the ratio between the residual parent or child farm demand and the joint residual parent plus child demand. For IGRID=1, the ranked NRDs to the residual parent model farm are scaled by the ratio (residual parent farm demand/joint residual parent+child farm demand). For IGRID>1, the ranked NRDs to the child model farm are scaled by the ratio (child farm demand/joint residual parent+child farm demand) and adopt NRD-Ranks and NRD-Use flag setting from the parent model NRD data input.

(Limitation: not allowed for WELLFIELD option).

Maximum number of non-routed delivery types (read if INRDFL = 1, if ILRG=0, or if ILGR>0, and for parent model grids where IGRID=1, or if ILGR>0, and for child model grids where IGRID>1 and INRDFL=1). MXNRDT is omitted if ILGR>0 and for child model grids where IGRID>1 and INRDFL=P. In this case, memory for NRD related attributes is allocated by twice the number of parent-MXNRDT to save old RNDRs for each type before scaling it down as a result of prorating for parent and child farm NRDs.

A farm related list of Row- and Column-coordinates or segment and reach numbers for a point of diversion will be read (only if SFR or SWR1 is specified in Name File). An additional flag for each.

•1 = List of Row- and Column-coordinates or segment and reach numbers for SFR is read for the entire simulation. (See Data Set 21a.)

•2 = List of Row- and Column-coordinates or segment and reach numbers for SFR is read for each stress period. (See Data Set 37a.)

For a parent model farm (IGRID=1) with a head-gate (SFR in Name File), for a child model farm without any stream network (IGRID>1; SFR not in Name File), and where a residual parent farm and child farm have equal farm ID:

•P = A point of diversion along the stream network defined for the parent model by row and column coordinates or segment and reach number (as defined by the parent model’s ISRDFL settting) is also used to receive the residual demand of child model farm in addition to the residual demand of parent model farm. No additional farm-specific SRD list entries are required for the child model.

The child model farm without a head-gate reach does not have any actual farm delivery from surface water from an own source, but may receive deliveries from the parent farm head gate subject to availability. Parent and child farms may either receive actual surface-water deliveries in full or at a reduced rate depending on whether their cumulative demand is less or more than the available supply:

•If the sum of residual demands of parent and child model farms exceeds any supply constraints, such as the available streamflow or surface-water allotment in the parent model head-gate reach, then

•the entire constraint will be diverted from the streamflow available at the parent farm’s head-gate reach, and

•the residual delivery requirement of both farms will be reduced to the respective constraint. This is accomplished by scaling the delivery requirement of the residual parent or child farm farm by the ratio [constraint/(parent farm demand + sum of demands of all child model farms)]. The reduced demand will be passed on to the farm budget.

•If the sum of residual demands of parent and child model farms does not exceed any supply constraints, then

•the child farm demand, in addition to parent farm demand, is diverted from the streamflow available at the parent farm’s head-gate reach, and

•the residual delivery requirement of both farms will by supplied in full and passed on to the farm budget.

Routed Surface-Water Delivery Flag (0, 1, –1, “P” possible):

•0 = no surface-water delivery exists.

•1 = fully-routed surface-water delivery may occur from the uppermost reach of a series of diversion-segment reaches located within a farm. Caution: Streamflow fully-routed through a conveyance network directly to a farm can only occur (1) if SFR is specified in Name File, (2) if at least one reach of a diversion segment is located within the farms, and (3) if streamflow is available.

•–1 = fully-routed surface-water delivery may occur from the uppermost reach of a series of reaches of any type of stream segment located within a farm. Caution: Streamflow fully-routed through a conveyance network directly to a farm can only occur (1) if SFR is specified in Name File, (2) if at least one reach of a any type of segment is located within the farms, and (3) if streamflow is available.

•P = The IRDFL flag setting defined for the parent model will be applied. Fully routed surface-water delivieries within a child model are subject to SFR being specified in the child model Name File and the existence of a respective segment (diversion segment for IRDFL=1; any type of segment for IRDFL=-1).

Semi-Routed Surface-Water Runoff Return Flow Flag (0, 1, 2, “P” possible):

•0 = No locations along the stream network are specified for any farm, where semi-routed runoff return flow is recharged into the stream network. Runoff is either automatically prorated over non-diversion-segment reaches located within a farm, or automatically recharged into one non-diversion-segment reach nearest to the lowest elevation of the farm.

•1 or 2 = For each farm, a location is specified anywhere along the stream network, where semi-routed runoff return flow is recharged anywhere in the active model domain. A farm-related list of row and column coordinates or segment and reach numbers for a point of runoff return flow recharge will be read (only if SFR is specified in Name File).

•1 = List of row and column coordinates or segment and reach numbers and target of Semi-routed Delivery to SFR or indirectly to SWR through an SFR segment is read for the entire simulation. (See Data Set 21b.)

•2 = List of row and column coordinates or segment and reach numbers and target of Semi-routed Delivery to SFR or indirectly to SWR through an SFR segment is read for each stress period. (See Data Set 37b.)

For a parent model farm (IGRID=1) with a head-gate (SFR in Name File), for a child model farm without any stream network (IGRID>1; SFR not in Name File), and where a residual parent farm and child farm have equal farm ID:

•P = A point of return flow recharge along the stream network for the parent model by row and column coordinates or segment and reach number (as defined by the parent model’s ISRRFL setting) is also used to receive the cumulative runoff return flow of the child model farm in addition the return flow of the parent-model farm. If the parent ISRRFL ≥ 1 and zero coordinates are specified for the return flow location of a parent farm, then the return flow from the child model is added to “automatic fully routed runoff return flow” prorated over drain segments found within the parent model farm or to “automatic semi-routed runoff return flow” discharged into a reach remote from the parent farm, but nearest to the lowest elevation of the parent farm. No additional farm-specific SRR list entries are required for the child model.

The absence of a SFR network within the child model domain does not allow the child farm to return runoff to any specified our automatically detected reaches. However, the child farm may return runoff to the parent farm’s return flow reaches, which may be specified or automatically detected as reaches within the farm domain or as a remote reach nearest to the lowest elevation of the parent farm.

Routed Surface-Water Runoff Return Flow Flag (0, 1, –1, “P” possible):

•0 = no surface-water runoff return flow possible (no SFR specified in Name File).

•1 = surface-water runoff may be returned as fully-routed return flow to a series of non-diversion-segment reaches located within a farm (prorated over each reach weighted by the reach length). Caution: Fully-routed return flow directly from a farm to a series of non-diversion-segment reaches can only occur (1) if SFR is specified in Name File and (2) if at least one reach of a non-diversion segment is located within the farm. Also, it occurs if segment and reach of farm in the SRD input file are set to 0.

•–1 = fully surface-water runoff may be returned as fully-routed return flow to a series of reaches of any segment of stream type located within a farm (prorated over each reach weighted by the reach length). Caution: Fully-routed return flow directly from a farm to a series of reaches of any type of stream segment can only occur (1) if SFR is specified in Name File and (2) if at least one reach of a non-diversion segment is located within the farm. Also, it occurs if the segment and reach of farm in the SRD input file are set to 0.

•P = The IRRFL flag setting defined for the parent model will be applied. Fully routed surface-water runoff return flow within a child model are subject to SFR being specified in the child model Name File and the existence of a respective segment (return flow to non-diversion segment for IRRFL=1; return flow to any type of segment for IRDFL=-1).

Surface-water allotment flag

(IALLOTSW > 1 not yet tested for parent model farm (IGRID=1) and child model farm (IGRID>1) straddling the parent/child model boundary and with equal farm ID):

0–No surface-water allotment specified,

1–Equally appropriated surface-water allotment height [L] specified per stress period (specification of diversions from a river into diversion segments in SFR input file required if ISRDFL = 1 or 2, or IRDFL = 1). (See Data Set 38.)

2–Prior appropriation system with Water Rights Calls [L3/T] (diversion rates from a river into diversion segments are simulated based on estimate of TFDR if ISRDFL = 1 or 2, or IRDFL = 1; specification of a farm-specific water rights calls list required for each stress period). (See Data Set 39.)

3–Prior appropriation system without Water Rights Calls [L3/T] (diversion rates from a river into diversion segments are simulated if ISRDFL = 1 or 2, or IRDFL = 1).

For a parent model farm (IGRID=1) and child model farm(s) (IGRID>1) and where a residual parent farm and child farm have equal farm ID:

P = use parent model equal appropriation allotment heights and bypass reading ALLOTSW per stress period. For child IALLOTSW=P and parent IALLOTSW=1, no additional data are required for the child model.

Allotment rates for the residual parent farm and the child farms are calculated on the basis of each area. Each child farm allotment rate is then added to the residual parent farm allotment rate. This joint allotment rate is then used to constrain the available streamflow in head-gate, from which water is diverted that accounts for the residual demands of the parent and child farms.

User specified closure criterion for simulated diversions into diversion segments if prior appropriation is chosen [L3/T] (only to specify if IALLOTSW> 1)

Optional routing information print flag if the SFR Package is specified in the Name file. If the model is as child model, IRTPFL is required if the SFR Package is specified in the Name file of either the parent or child model.

Information regarding the routing of farm deliveries and farm runoff return flows will be written either to the listing file or to a separate ASCII file, called ROUT.OUT.

The information regarding deliveries tells whether the farm can potentially receive either:

(a) fully-routed deliveries from the first, most upstream located reach of a sequence of automatically detected delivery-segment reaches within a farm, or whether

(b) the farm can potentially receive semi-routed deliveries from specified stream reaches.

The information regarding return flows tells whether potential runoff from the farm is returned either

(a) full-routed to automatically detected return flow-segment reaches within a farm, over which the runoff return flow is prorated, weighted by the length of each reach, or

(b) semi-routed to specified stream reaches, or in lack of this first two options,

(c) semi-routed to automatically detected return flow-segment reach nearest to the lowest elevation of a farm.

Indicates that no optional flags for auxiliary variables are specified. NOAUX is only required if Flag Blocks are used. If flags are read in Item 2b from a single line (as before in FMP1), then no entry is required if no optional flags for auxiliary variables are specified.

AUX “abc” Defines an auxiliary variable, “abc”, which will be read for each farm-well as part of Items 4 and 23. Up to five auxiliary attributes “abc” can optionally be specified, each of which must be preceded by “AUX.” These values will be read after the QMAXfact or QMAX variable of Item 4 or Item 23, respectively.

AUX QMAXRESET The specification of the optional flag “AUX QMAXRESET” for {option} in Item 2 will prompt FMP to reset QMAX as simulated by the MNW Package to the default QMAX as defined by FMP at the beginning of each time step. The optional flag “AUX QMAXRESET” requires FMP to read an auxiliary variable after the QMAXfact or QMAX variable of the farm wells list in Items 4 or 23, or after any other preceding auxiliary variable (e.g., AUX NOCIRNOQ). If a “1” is read, then the MNW-simulated QMAX is reset to the default QMAX in the first iteration of each time step.

AUX NOCIRNOQ The specification of the optional flag “AUX NOCIRNOQ” for {option} in Item 2 will prompt FMP to limit the distribution of farm pumpage to farm wells, whose row and column coincides with a top layer cell with a current irrigation requirement from active crops. “NOCIRNOQ” stands for “no crop irrigation requirement (CIR), no pumping (Q).” The optional flag “AUX NOCIRNOQ” requires FMP to read an auxiliary variable after the QMAXfact or QMAX variable of the farm wells list in Item 4 or 23, or after any other preceding auxiliary variable (e.g. AUX QMAXRESET). The auxiliary variable for “AUX NOCIRNOQ” is defined to be a binary parameter that tells which wells are selected for the NOCIRNOQ option. If a “1” is read, then the respective well is selected for setting its maximum capacity to zero if, during a particular time step, no crop irrigation requirement of the top layer cell exists. At each new time step the maximum capacity of such a select well will be reset to the default value.

Identifies a child model grid with respect to a parent model for FMP transfer of properties.

NOOPT Indicates that no Options are specified. NOOPT is only required if Flag Blocks are used. If flags are read in Item 2b from a single line (as before in FMP1), then no entry is required if no Options are specified.

CBC Indicates that memory should be allocated to store cell-by-cell flow for each well to make these flows available for use in other process.

NOPRINT Indicates that a list of specified farm well attributes will not be printed to the list file.

WELLFIELD Allows a series of irrigated farms to receive their cumulative irrigation demand as simulated non-routed deliveries from well fields simulated as virtual farms. A virtual well-field farm with one or several wells (well fields) receives a cumulative pumping requirement equal to the cumulative irrigation delivery requirement of irrigated farms that are supplied by the well field. If the cumulative demand exceeds the cumulative maximum pumping capacity of the well field, then other well field can supply the residual demand. The cumulative pumpage of the well field that is equal or less than the desired demand will then be re-distributed to the farms supplied by the well field weighted by the total delivery requirement (or residual delivery requirement for lower priority well fields) of the receiving farms. FMP3 then applies this re-distributed rate as non-routed deliveries to the respective farms.

For farms that receive water from a particular well field, in Item 36, the non-routed delivery volume may be set to a dummy zero, as the non-routed delivery is simulated by the well-field option. The rank of the non-routed delivery, NRDR, must consistently be equal to the priority of the well-field. The NRDU flag has to be set to “minus the Farm ID of the virtual farm that contains the well field” for the farms receiving water from the respective well field. For the virtual well-field farm itself, the NRDU flag has to be set to one.

For first priority well field and farms receiving water from that well field:

NRDVt1(NFARMS) = 0 (dummy zero: simulated when option WELLFIELD is set)

NRDRt1(NFARMS) = 1 (Type 1 must be of rank 1 for well-field farm and for receiving farms)

NRDUt1(FIDrec-wf-1) = negative value of Farm-ID of virtual well-field farm

NRDUt1(FIDwf-1) = 1

NRDUt1(FIDother) = 0

For second priority well field and farms receiving water from that well field:

NRDVt2(NFARMS) = 0 (dummy zero: simulated when option WELLFIELD is set)

NRDRt2(NFARMS) = 2 (Type 2 must be of rank 2 for well-field farm and for receiving farms)

NRDUt2(FIDrec-wf-2) = negative value of Farm-ID of virtual well-field farm

NRDUt2(FIDwf-2) = 1

NRDUt2(FIDother) = 0

For a well field of priority n and farms receiving water from that well field:

NRDVtn(NFARMS) = 0 (dummy zero: simulated when option WELLFIELD is set)

NRDRtn(NFARMS) = n (Type n must be of rank n for well-field farm and for receiving farms)

NRDUtn(FIDrec-wf-n) = negative value of Farm-ID of virtual well-field farm

NRDUtn(FIDwf-n) = 1

NRDUtn(FIDother) = 0

NRDV, NRDR, NRDU definitions see “Non-Routed Surface-Water Deliveries” below

FIDrec-wf-n = Farm-ID of a farm receiving water from well-field n;

FIDwf-n = Farm-ID of a virtual well-field farm n.

The non-routed delivery type that originates from the lowest priority well field cannot be higher than the maximum number of non-routed delivery types, MXNRDT.

RECOMP_Q_BD Re-computation of the Farm Process FM-routine is invoked at the end each time step loop.

MNWCLOSE Head- and residual-closure criteria of the MODFLOW solver Package will be adjusted to allow convergence of the FMP pumping requirement to pumping simulated by the linked MNW1 or MNW2 packages.

Criterion for actual MNW pumping rate to converge to FMP pumping requirement (real number)

Fraction of reduction of head-change closure criterion if QCLOSE was not met [ ].

Fraction of reduction of residual-change closure criterion if QCLOSE was not met [ ].

Minimum fraction of model cell thickness before pumping reduction is initiated, same as PHIRAMP (Niswonger and others, 2011)

Minimum saturated thickness of model cell before pumping reduction is initiated.

Parameter name for list of parameter farm-wells (called for each stress period to activate a list of parameter wells). This name can consist of 1 to 10 characters and is not case sensitive.

All parameter names must be unique.

Parameter type (the only allowed parameter type is QMAX, which defines values of the volumetric maximum well capacity).

Parameter value (multiplier applied to parameter-wells).

Number of parameter farm-wells included in the parameter-well-list related to one parameter.

When NLST is set to “P,” up to the maximum number of parent model parameter farm-well list entries may be used as child model parameter farm wells in well locations where the child model farm ID coincides with the parent model farm ID. For child model parameter farm wells pulled from parent model parameter farm wells, the list entries printed to the list file are appended to the list entries of parameter farm wells specified for the child model under a separate parameter name.

Parent parameter farm wells are excluded from being used for a child model farm if the same child model parameter wells are specified for that child model farm.

INSTANCES Optional keyword that designates a parameter as time varying. The keyword is not case sensitive; that is, any combination of the same characters with different case can be used. If INSTANCES is present, it must be followed by a value for NUMINST. If INSTANCES is absent, PARNAM is non-time varying and NUMINST should not be present.

Number of instances for a time-varying parameter, where each instance is a list of wells and associated maximum capacities. If the keyword INSTANCES is present, it must be followed by a value for NUMINST. If INSTANCES is absent, NUMINST should not be present.

Layer number of cell containing the farm-well (for farm-wells linked to multi-layer wells defined in the Multi‑Node Well Package: Layer No. = 0)

Row number of cell containing the farm well

Column number of cell containing the farm well

Farm-well identity associated with the farm well (to establish a link of a farm-well to a well defined in the Multi-Node Well Package: use “negative” Farm-Well-ID, for example, –10)

Farm identity to which the farm-well is attributed

Maximum Well Capacity factor (QMAXfact × PARVAL = QMAX) [L3/T].

Multi-Node Well Package Version 2 Well Name that will be linked to the farm process. MNW2NAM is a character variable of maximum length 20 that is read only when MNW2 package is active and Farm-Well-ID < 0. When linked to MNW2 the the layer, row and column specified by well MNW2NAM in MNW2 will overwrite the previously defined values. See also WELLID in the MNW2 package.

Represents any auxiliary variables for a farm-well that have been defined in Item 2. The auxiliary variables must be present in each repetition of Items 4 and 22.

If the optional flag for {Option} in Item 2 is set to “AUX QMAXRESET,” then the auxiliary variable for [xyz] in column 7 of the farm wells list is defined to be a binary parameter that tells when to reset the MNW-simulated QMAX rate to the FMP-defined default QMAX rate.

•0 = The MNW-simulated QMAX is reset at the beginning of each stress period.

•1 = The MNW-simulated QMAX is reset at the beginning of each time step.

If the optional flag for {Option} in Item 2 is set to AUX NOCIRNOQ, FMP will limit the distribution of farm pumpage to farm wells, whose row and column coincides with a top layer cell with a current irrigation requirement from active crops. The optional flag “AUX NOCIRNOQ” requires FMP to read an auxiliary variable after the QMAXfact or QMAX variable of the farm wells list in Item 4 or 22, or after any other preceding auxiliary variable (e.g. AUX QMAXRESET). The auxiliary variable for “AUX NOCIRNOQ” is defined to be a binary parameter that tells which wells are selected for the NOCIRNOQ option.

•If a “1” is read, then the respective well is selected for setting its maximum capacity to zero if, during a particular time step, no crop irrigation requirement of the top layer cell exists. At each new time step the maximum capacity of such a select well will be reset to the default value.

The parameter(s) in column 7 of the well list are ignored, if the option flag “AUX QMAXRESET” and AUX NOCIRNOQ are not specified.

Time-step in climate time series. The length of a time series time step must consistently be equal to the MODFLOW time unit chosen in the Discretization File (ITMUNI).

For ICUFL = 3 or IRTFL = 3, the MODFLOW time unit must be days (ITMUNI = 4). For IPFL = 3 (while ICUFL ≠ 3, and IRTFL ≠ 3), all MODFLOW time units are possible (seconds, minutes, hours, days, years; ITMUNI = 1, 2, 3, 4, 5). However, ITMUNI = 1 or 2 for units of seconds or minutes should be avoided for very long periods of simulation due to the possibility of insufficient computer memory.

for ILGR > 0 and IGRID > 1, up to the maximum number of parent model nonparameter farm-well list entries may be used as child model nonparameter farm wells in well locations, where the child model farm ID coincides with the parent model farm ID. For child model nonparameter farm wells pulled from parent model nonparameter farm wells, the list entries printed to the list file are appended to the list entries of nonparameter farm wells specified for the child model.

Nonparent parameter farm wells are excluded from being used for a child model farm if the same nonparameter wells are already specified for that child model farm.

If the optional flag for {Option} in Item 2 is set to “AUX QMAXRESET,” then the auxiliary variable for [xyz] in column 7 of the farm wells list is defined to be a binary parameter that tells when to reset the MNW-simulated QMAX rate to the FMP-defined default QMAX rate.

The optional flag “AUX NOCIRNOQ” requires FMP to read an auxiliary variable after the QMAXfact or QMAX variable of the farm wells list in Item 4 or 22, or after any other preceding auxiliary variable (e.g. AUX QMAXRESET). The auxiliary variable for “AUX NOCIRNOQ” is defined to be a binary parameter that tells which wells are selected for the NOCIRNOQ option.
