Automatic watershed delineation and hydrological modeling

• Using digital terrain data to automatically depict watersheds and sub watersheds
• Automatically calculate geometric watershed data, such as area, slope, average elevation, maximum flow distance, etc
• Calculate hydrological basin data such as concentrated time, number of curves, and infiltration parameters with a small amount of input
• WMS contains industry standard equations for calculating sub basin lag time and concentration time
• Add any number of internal exit points to allow WMS to automatically segment watersheds
• Manipulate river networks to represent human characteristics or propose changes to the watershed
• Overlay derived watershed boundaries to match your understanding of the watershed

Supports most industry standard hydrological models

• The license for WMS Floodplain or higher includes interfaces to the following industry standard hydrological models:
• HEC-1
• HEC-HMS
• TR-20
• TR-55
• Rational methods
• Modlat
• OC (Orange County, California) Rationality
• OC Hydrology
• High density lipoprotein
• National traffic statistics
• Convert and compare the watershed results developed for a model with any other models supported by WMS
• Read and compare observed hydrological hydrographs with calculated ones

Hydraulic modeling and floodplain mapping

• Define river centerline and embankment stations
• Define cross-sectional position
• Automatically cut cross-sections and derive Manning's roughness values from elevation and ground material data
• Export the cross-section to HEC-RAS or a simplified hydraulic model for dam rupture
• Run hydraulic model and read water level elevation back to WMS
• Read water surface elevation data from hydraulic models or manually input known water surface elevations
• Creating flood range and depth maps using digital terrain data and water surface elevation data points
• Link peak flow or complete hydrological hydrographs from any WMS supported hydrological model to the HEC-RAS hydrological model

Rainwater channel modeling

• Draw a rainwater channel network or import the network from GIS
• Calculate the elevation, length, and slope of pipelines based on basic elevation data
• Link the rainwater discharge network to your hydrological model data
• Export hydrological model data and rainwater discharge network to EPA-SWMM or XP-SWMM
• Import existing EPA-SWMM or XP-SWMM files into WMS

Two dimensional (distributed) hydrology

• WMS supports 2D models:
• The US Army Corps of Engineers (USACE) GSSHA model
• HMS version of quasi distributed MODClark method
• Flood prediction (depth and velocity of the entire two-dimensional domain)
• Thunderstorm (localized rainfall) flood analysis
• Analysis of surface water accumulation and infiltration
• Wetland modeling
• Modeling the Impact of Land Use Change
• Modeling the interaction between groundwater and surface water
• Sediment and pollutant modeling

Import what you need

• USGS DEM - Download and use any format of DEM from USGS
• USGS NED data - seamless elevation data can be downloaded and read into WMS
• ArcGIS Raster (ASCII format) - Reading elevation or attribute data in grid format from ArcGIS
• ESRI Shape File - Read all shapes and attributes into WMS
• DXF and DWG CAD files - WMS now supports the latest versions of DXF and DWG
• WMS can read TIFF, JPEG image files -/images, and geographic reference information
• Any data supported by ArcGIS can be read into WMS (requires ArcGIS license, compatible with ArcGIS 10.0)

WMS 11.1 System Requirements

• Operating system: Windows 10
• RAM: Recommended 16GB or more
• CPU: WMS software is CPU intensive. Some models and utilities integrated with WMS can utilize multiple processor kernels simultaneously. We recommend the fastest CPU that your budget allows.
• Storage: The recommended storage capacity will vary depending on personal data requirements. The latest version of WMS is disk I/O intensive.

-Mechanical hard drives: basic performance

-SATA solid-state drives: better performance

-NVMe Solid State Drive: Best Performance

• Graphics card: Independent graphics card is superior to integrated graphics card. Basic or mid-range NVidia cards designed specifically for gaming have the best performance.
• Display resolution: 1920 x 1080 or higher
