Groundwater Lateral Flux
This category is dependent on selection of the Link to MODFLOW 2000 RIP ET method in the Groundwater Computation category; see Link to MODFLOW 2000 RIP ET. This category should be used in conjunction with the “Groundwater Elevation” category on which a method other than “None” should be selected.
* None
This is the default method. There are no slots associated with this method.
* Summation
Note:  RiverWare’s connection with MODFLOW is currently not functional. This method has been disabled and cannot be selected. An error will be posted at model load if this method was previously selected. Contact CADSWES for help.
This method sums fluxes from the MODFLOW cells and writes the summed values into the RiverWare GroundWater Storage object. The GainLoss for each cell in the GroundWater Lateral Flux Map slot is gathered from MODFLOW and set in the GroundWater Lateral Flux from MODFLOW slot. For each GroundWater object the individual lateral fluxes will be summed and mapped to the GroundWater Storage.Lateral Flux from MODFLOW. Figure 8.7 shows the summation equation.
Slots Specific to This Method
 GroundWater Lateral Flux Map
Type: Table slot
Units: No units
Description: Maps a MODFLOW cell to a GroundWater Storage object specified on the subbasin
Information: The layer, row, and column of each MODFLOW GHB cell is input by the user and the corresponding GroundWater object needs to be set as the row title.

 GroundWater Lateral Flux from MODFLOW
Type: Table Series slot
Units: Flow
Description: Each MODFLOW GHB cell specified in the GroundWater Lateral Flux Map slot will contain a Lateral Flux value transferred to RiverWare from MODFLOW. The column labels are automatically defined at the beginning of the run, in MODFLOW initialization. The user unit configuration (cfs, ft3/day, and so on) selected on this slot must match with the units used in MODFLOW.
Information: Transferred to RiverWare from MODFLOW
I/O: Output only
