• Create a DEM from a wide range of data sources.
• Remove flat and pits from the DEM using advanced filling and breaching algorithms.
• Map the drainage path for any point in the terrain.
• Automatically delineate stream networks complete with Horton ordering and full range of hydrologic attributes.
• Automatically breakup a catchment into a subcatchment network.
• Automatic calculation of subcatchment impervious proportions.
• Integrates with 12d to map drainage catchments for pits and other structures in urban environments.
• Use bathymetry and lake data to develop stage – area – volume relationships for reservoirs and lakes.
• Chart a wide range of hydrologic attributes of subcatchments.
• Visualise your project with 3D OpenGL graphics.
• Export to GoogleEarth for powerful presentations.
• Seamless integration with any external software via a macro language. Buit-in scripts allow creation of files compatible with a wide range of software.

CatchmentSIM provides integration with eWater's music for automated setup of music models. More information on CatchmentSIM's music integration can be seen in our brochure, or by watching the video below.

CatchmentSIM can be used to automate the identification of aquaplaning risk areas in 12d road design surfaces.

CatchmentSIM provides integration with 12d Model for fast and efficient mapping of catchments and flow paths over 12d Model TINs or Super TINs. It can be used to automate the mapping of drainage pit/inlet catchments as well as flow paths and can also model fence lines and other flow obstructions.
