3. Detention Pond Design

Example 3 explains the process of creating, designing, and assessing a detention pond using SWMM. The detention pond, designed for water quality capture and peak flow control, employs storage components, orifices, and weirs. It models an urban catchment akin to Examples 1 and 2. Urban runoff management relies on storage structures for peak flow reduction and pollutant elimination, adapting design standards to better comprehend environmental repercussions. Besides averting floods, these structures must manage frequent minor runoff events that contribute to initial pollution and harm water body quality.
