WMS 10.0 - The All-in-one Watershed Solution

WMS Logo


Harness the entire spectrum of watershed analysis tools with WMS - the all-in-one hydrologic and hydraulic solution.


The complete all-in-one watershed solution

  • GIS Tools
  • Web-based data acquisition tools
  • Terrain data import and editing tools
  • Automated watershed delineation & hydrologic modeling
  • Support for the most industry standard hydrologic models
  • Step-by-step hydrologic modeling wizard
  • Hydraulic modeling & floodplain mapping
  • Storm drain modeling
  • 2D (Distributed) Hydrology
  • Integration with FHWA hydraulic calculation software
  • Export WMS animations to GoogleTM Earth

Automated watershed delineation & hydrologic modeling

  • Automatically delineate a watershed and sub-basins using digital terrain data
  • Automatically compute geometric basin data such as area, slope, mean elevation, maximum flow distance and more
  • With a small amount of input, compute hydrologic basin data such as time of concentration, curve number, and infiltration parameters
  • Industry standard equations for computing sub-basin lag times and times of concentration are included with WMS
  • Add any number of interior outlet points and let WMS subdivide the watershed automatically
  • Manipulate stream networks to represent man-made features or proposed changes to the watershed
  • Override derived basin boundaries to match your knowledge of the watershed

Support for most industry standard hydrologic models

  • A license of WMS Hydrology or greater includes an interface for the following industry standard hydrologic models:
    • HEC-1
    • HEC-HMS
    • TR-20
    • TR-55
    • Rational Method
    • MODRAT
    • OC (Orange County, California) Rational
    • OC Hydrographic
    • HSPF
    • National Streamflow Statistics
    • Convert and compare the results of a watershed developed for one model with any of the other models supported in WMS
    • Read and compare observed hydrographs with computed hydrographs

Hydraulic modeling & floodplain mapping

  • Define a stream centerline and bank stations
  • Define cross section locations
  • Automatically cut cross sections and derive Manning's roughness values from elevation and ground material data
  • Export cross sections to the HEC-RAS or Simplified Dam Break hydraulic models
  • Run the hydraulic model and read the water elevations back into WMS
  • Read water surface elevation data from a hydraulic model or manually input known water surface elevations
  • Create flood extents and flood depth maps using digital terrain data and water surface elevation data points
  • Link the peak flow or complete hydrograph from any of the WMS-supported hydrologic models to an HEC-RAS hydraulic model

Storm drain modeling

  • Draw a storm drain network or import a network from GIS
  • Compute elevations, lengths, and slopes of pipes from underlying elevation data
  • Link the storm drain network to your hydrologic model data
  • Export the hydrologic model data and the storm drain network to EPA-SWMM or XP-SWMM
  • Import existing EPA-SWMM or XP-SWMM files into WMS

2D (Distributed) hydrology

  • WMS supports 2D models:
    • The US Army Corps of Engineers (USACE) GSSHA model
    • The HMS version of the quasi-distributed MODClark method
  • Flood forecasting (depth and velocity over entire 2D domain)
  • Thunderstorm (localized rainfall) flood analysis
  • Surface ponding and infiltration analysis
  • Wetland modeling
  • Land use change impact modeling
  • Groundwater/surface-water interaction modeling
  • Sediment and contaminant modeling

Import what you need

  • USGS DEMs - download and use any format of DEM from the USGS
  • USGS NED data - seamless elevation data can be downloaded and read into WMS
  • ArcGIS Raster (ASCII format) - read elevation or attribute data in gridded format from ArcGIS
  • ESRI Shape files - read all shapes and attributes into WMS
  • DXF and DWG CAD files - WMS now supports the latest versions of DXF and DWG
  • TIFF, JPEG image files - /images along with geo-referencing information can be read by WMS
  • Any data supported by ArcGIS can be read into WMS (ArcGIS license required, compatible with ArcGIS 10.0)
