Retention pond vs detention basin.

Detention Ponds. A detention pond is a dry structure that has a riser located at the bottom of the basin. Whenever water flows into the detention pond, it is more likely to drain right out and stay dry. Detention ponds may have turf or wild grasses.

A retention basin isMay 29, 2023 · The difference between a detention basin and a retention basin, is the presence or absence of a permanent pool of water, or pond. The water level in both types of basins is controlled outflow orifice. A detention basin has this orifice at the bottom of the basin and does not have a permanent pool of water. The equation for converting detention pond volume in mm over the watershed area, Vs, to m3, is: Vst = (10) (Vs) (A) m3. In S.I. units the runoff depth, Qb or Qa, can be calculated from known values for the peak runoff rate, time of concentration, and watershed area, with the equation: Q - 360 (qp tc/A).
