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 Floodplain 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)
