Drains can be modeled using points, arcs and/or polygons in a [[GMS:MODFLOW Conceptual Model Approach|conceptual model]]. The return cell cannot be specified in the conceptual model. This is because the conceptual model is independent of the grid and, in fact, there may be no grid at all when the conceptual model is defined.

The return cell cannot be specified in the conceptual model. This is because the conceptual model is independent of the grid and, in fact, there may be no grid at all when the conceptual model is defined. When GMS performs the '''Map→MODFLOW''' command, the return cell is always set to be the highest active cell above the drain cell. This can later be changed in the ''Drain package'' dialog. | ||

The ''MODFLOW Drain Return Package'' dialog allows the user to edit the location and the input values associated with each drain boundary condition. Drain boundary conditions cannot be created or deleted from this dialog. They can be created and deleted via the '''Map → MODFLOW''' command, or by using the [[GMS:MODFLOW Source/Sink Dialog|''MODFLOW Source/Sink'' Dialog]]. | The ''MODFLOW Drain Return Package'' dialog allows the user to edit the location and the input values associated with each drain boundary condition.
