The performance of the pond in terms of pollutant retention efficiencies was estimated by comparing the influent and effluent pollutant concentrations.As you can see, the post-development increased the Peak runoff rate to 79 cfs from 36 cfs in its natural state. Our goal now is to design a detention pond that will produce an outflow hydrograph that looks similar to the pre-developed (red) hydrograph for the 2, 10 and 100-year events. Design Your Detention PondThe 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).
