Watershed Modelling (WSM)


The Watershed modelling System (WMS) has been developed by AQUAVEO who have developed a series of tools for the visualisation of surface and groundwater hydrology and hydraulics. Their software packages are widely used by consulting firms, universities and government agencies globally.          


WMS is a watershed analysis tool that provides hydrologic and hydraulic modelling at watershed scales.  

Promoted as an 'all-in-one' watershed solution the software provides access to a range of catchment and spatial tools that can be accessed via a simple graphic user interface.

WMS User Interface

WMS includes tools include:

  • 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

The automated watershed delineation uses digital terrain data to automatically delineate a watershed and sub-basins.  As part of the delineation process, basin data such as area, slope, mean elevation, maximum flow distance, and many other commonly-used hydrologic parameters are automatically computed.

The floodplain modelling and mapping applies interpolation algorithms to allow creation of flood extents and flood depth maps using digital terrain data and water surface elevation data points. The Storm Drain Network Modeling create a complete storm drain network with unlimited pipes and nodes.

Depending on the user license, WMS also includes in interface for a range of industry standard hydrological models.
