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.
