The Watershed Modeling System (WMS) is a comprehensive graphical modeling environment for all phases of watershed hydrology and hydraulics. WMS includes powerful tools to automate modeling processes such as automated basin delineation, geometric parameter calculations, GIS overlay computations (CN, rainfall depth, roughness coefficients, etc.), cross-section extraction from terrain data, and more! WMS supports hydrologic modeling with HEC-1, HEC-HMS, TR-20, TR-55, Rational Method, NFF, MODRAT, OC Rational, HSPF, xpswmm, and EPA-SWMM. Hydraulic models supported include HEC-RAS, xpswmm, EPA-SWMM, SMPDBK, and CE-QUAL-W2. 2D distributed hydrologic models (including channel hydraulics and groundwater interaction) can now be created with GSSHA, developed by the US Army Corps of Engineers. All modeling is handled by a GIS-based data processing framework that makes the task of watershed modeling and mapping easier than ever before.
