This tab is on the Water Balance Subregions dialog box.
Return Flow Locations is used to specify SEMI_ROUTED_RETURN in the Farm Process SURFACE_WATER block.
Each Water Balance Subregion can have multiple return flow locations. Unlike most other properties of Water Balance Subregion, the return flow locations of Water Balance Subregion must be edited individually. The Number of return flow locations is specified for the selected Water Balance Subregion. For each return flow, the user identifies the object that defines the SFR stream from to the return flow occurs and identifies a vertex in the cell where the return flow takes place.
Fraction is the fraction of surface runoff that is applied the return flow reach. If Fraction is specified for a Water Balance Subregion, then the fractions for all return flow locations for each Water Balance Subregion should sum to 1.
