Subject: Infiltration Data in SWMM 5
1. Five parameters for Horton Infiltration,
2. Three parameters for Green-Ampt and
3. Two parameters for CN infiltration, one parameter (conductivity) has been deprecated by the EPA in SWMM 5. The Drying Time is used to regenerate the Infiltration Rate for continuous simulation. Only two parameters are now used for CN infiltration: The CN value itself and the drying time.
If you are using Non linear Reservoir Modeling in SWMM 5 there are
