Detention basin

Identify appropriate locations for flood detention basins 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. (5:02)

Feasible wetland locations are identified by inspecting flow paths and using the watershed tool. The size for wetlands is assessed using the catchment size and land-use information. (9:09)

Terrain editing tools are used for filling up a ditch and to create a natural remeandering stream that can support biodiversity and wildlife. Learn to edit cross-sections and see how you can use the soil balance to avoid soil transportation. (13:35)

In the 19th century Lake Søborg, Denmark, was drained. Now, the plan is to recreate the lake. See this video for inspiration on how to start planning the rewetting of drained areas using terrain editing and surface water analyses. (23:48)
