Constant Infiltration Model

The Constant Infiltration Model allows representation of an infiltration drainage surfaces, such as a permeable pavement, that has a constant infiltration loss to groundwater.

This infiltration loss is represented by the Infiltration Loss Coefficient field in the runoff surface definition. In other respects, the ConstInf surface acts in the same way as a fixed runoff surface.
