Hydrology in SWMM5

Hydrologic Modeling Features

SWMM accounts for various hydrologic processes that produce runoff from urban areas. These include:

· time-varying rainfall
· evaporation of standing surface water
· snow accumulation and melting
· rainfall interception from depression storage
· infiltration of rainfall into unsaturated soil layers
· percolation

Infiltration in InfoSWMM and SWMM5

Infiltration in InfoSWMM and SWMM5

Infiltration is the process of rainfall penetrating the ground surface into the soil over the pervious areas of Subcatchments.

InfoSWMM H2OMap SWMM InfoSWMM SA offers three choices for modeling infiltration:

Horton’s Equation

This method is based on empirical observations showing that infiltration decreases exponentially from … Read the rest
