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
