Segment Tab

This tab is on the SFR: Stream-Flow Routing package pane of the MODFLOW Features tab of the Object Properties dialog box. It is used to specify the hydraulic conductivity and other properties of the stream segment at the upstream and downstream ends of the segment. The properties at intermediate locations will be determined by linear interpolation between the values at the upstream and downstream ends.

The Starting time and Ending time of each time period is specified on the Time tab

Hydraulic conductivity and Hydraulic conductivity multiplier

•If parameters are not used, Hydraulic conductivity is the hydraulic conductivity of the streambed at the upstream or downstream end of this segment (units of length per time).

•If parameters are used, Hydraulic conductivity multiplier is a factor used to calculate hydraulic conductivity of the streambed at the upstream end of this segment from the parameter value (in units of length per time). The hydraulic conductivity will be the parameter value (specified in the MODFLOW Packages and Programs dialog box) times the value of the Hydraulic conductivity multiplier.

Streambed thickness is the thickness of streambed material at the upstream or downstream end of this segment (in units of length).

Streambed elevation is the elevation of the top of the streambed at the upstream or downstream end of this segment (in units of length).

Stream width is the average width of the stream channel at the upstream or downstream end of this segment (in units of length).

Stream depth is the average depth of water in the channel at the upstream end of this segment (units of length). The stream stage in a reach is assumed to equal the elevation of the top of the streambed plus the depth of water.
