WMS:SWMM

The Storm Water Management Model (SWMM) is a hydrologic and hydraulic analysis tool used primarily for designing and analyzing storm drain systems. Hydrologic parameters are defined to obtain hydrographs and peak flows which can then be fed into the hydraulic component of the model. The hydraulic component lets engineers analyze the capacity of a current storm drain system or design a system to meet certain inflow conditions.

WMS supports both EPA SWMM, developed by the Water Supply and Water Resources Division of the US Environmental Protection Agency’s National Risk Management Research Laboratory, and xpswmm, developed by XP Software. WMS 8.1 and later versions contain an interface to SWMM. The SWMM model can be added to a paid edition of WMS.
