The HYD: HYDMOD package pane is on the MODFLOW Features tab of the Object Properties dialog box. This pane is only visible if the HYDMOD package is selected.
HYDLBL is a label for the data that will be saved to file. Only ASCII characters are allowed in HYDLBL.
For the Basic and Subsidence packages, that data that are saved to file can either be the values at the cell or interpolated values between neighboring cells. INTYP allows you to choose between these options. Interpolation can only be selected when a point object on the top view of the model is being used to define the hydrograph location.
The check boxes for the BAS, SUB, and SFR packages allow the user to select what sort of data will be written to file. With the SUB package, the user must also specify the names of the layer group and no-delay bed. If several model layers are associated with a particular no-delay bed, the user must also specify the layers for which data will be saved.
For some types of HYDMOD observations, HYDMOD requires "offsets" to tell where in the cell the observation is located. With point objects, ModelMuse obtains that information from the precise location of the point object. With other sorts of objects, the observation is treated as being at the center of the cell.
