Sustainable drainage system

The watershed tool is used to identify which sub-catchment to disconnect, and flow paths are analysed to place detention storage. Initial assessments of water volumes help dimension basins. Terrain edit tools are used to evaluate different project ideas.

Development site

Initial surface water conditions of a development site are investigated. Different project ideas for the area are tested by modifying the elevation model. A high-level plan for robust surface water management is developed by reserving space for a detention basin.

Detention basin

Appropriate locations for flood detention basins are identified using the watershed tool and flow paths. Detention volumes are created with terrain edit tools and the overall impact on flood extent is assessed using the Flash Flood Map.

Strategic planning

Catchments are used as a natural way to divide a city into areas that can be planned independently. Flow paths are used to identify where water can flow safely on the surface, and the terrain edit tools are used to explore strategies for diverting and retaining water.
