WebThe invention discloses a method for calculating a rainfall ponding depth of a catchment area based on a DEM (digital elevation model), belonging to the technical field of … Webflow is able to enter as the ponding water filters through the soil media. With this design configuration, an overflow structure in the bioretention area is not required. Utilize a low-flow diversion or flow splitter at the inlet to allow only the design storm volume (i.e. the Stormwater Retention Volume (SWRv)) to enter the facility (Calculations
