The primary design parameter for sizing Detention Basins is the water quality volume (WQV). The WQV, or portion thereof, is equal to the minimum volume of the Detention Basin, which does not include any additional volume due to overflow events and freeboard. Freeboard is defined and described below. Network theory and optimization would also help to select the location and size of retention basins in a watershed, which results in the most cost-effective basin configuration that is also ...A detention basin or retarding basin is an excavated area installed on, or adjacent to, tributaries of rivers, streams, lakes or bays to protect against flooding and, in some cases, downstream erosion by storing water for a limited period of time.

Jul 1, 2007 · Since the 1970s, stormwater detention has been widely accepted as an effective means to reduce the developed peak flow to its historical rate. A detention basin is often designed as a regional flood control facility to reduce the 10- and 100-year runoff releases. Figure 1. Detention Basin Click here to enlarge image. • The primary retention basin outlet normally consists of a catch basin grate, catch basin side inlets, and the conduit that conveys discharges from the retention basin during all but the least frequent precipitation events. • The primary outlet should be sized to convey the 10% AEP design storm.

Detention Basins and Ponds. Retention basins, also known as “wet ponds”, are typically used for flood control in subdivisions and on commercial properties to decrease peak flows and slowly release collected rainfall runoff over a longer period to reduce local flash flooding. Wet ponds can also be designed for “extended” …A retention basin provides an area to hold water from a small surrounding drainage area that would otherwise flow into other areas. The water remains in the local area that it was deposited in. This is opposed to a detention basin that holds water for a limited period of time from a larger basin area to prevent flooding and releases all the water contained in …
