Refactoring the SWMM 5 Help File – Routing in SWMM5

Routing in SWMM5

Flow Routing

Flow routing within a conduit link in SWMM is governed by the conservation of mass and momentum equations for gradually varied, unsteady flow (i.e., the Saint Venant flow equations). The SWMM user has a choice on the level of sophistication used to solve these equations:… Read the rest

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
