description
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.he program’s modular design enables the user to select modules in custom combinations, allowing the user to choose only those hydrologic modeling capabilities that are required. Additional WMS modules can be purchased and added at any time. The software will dynamically link to these subsequent modules at run time—automatically adding additional modeling capability to the software.
