WMS 11.3 - The All-in-one Watershed Solution

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

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

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

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

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)

WMS is developed by Aquaveo, an engineering services company with many years of experience developing watershed modeling solutions.

Operating System: Windows 11
RAM: 16GB or more recommended
CPU: WMS software is CPU intensive. Some models and utilities integrated with WMS can take advantage of multiple processor cores simultaneously. We recommend the fastest CPU your budget allows.
Storage: Recommended storage amount will vary depending on individual data requirements. Latest versions of WMS are very disk I/O intensive.
- Mechanical hard drive: Basic performance
- SATA solid state drive: Better performance
- NVMe solid state drive: Best performance
Graphics: A dedicated graphics card is better than integrated graphics. A basic or mid-range nVidia card designed for gaming works best.
Display Resolution: 1920 x 1080 or greater
