Determine the required area (in ft ) of a bioretention basin to service runoff from a shopping complex with 4 .2 acres of paved parking, 1.1 acre of sidewalks, 0.5 acre of landscaping. The 24-hr design storm is 1 inch. Use the empirical coefficients in Small Storm Hydrology method. There is no underdrain pipe for the bioretention basin. Use the following guidelines for the design: Ponding depth = 12 inch Media bed: 36 inches deep, porosity = 0.30 Gravel bed: 24 inches deep, porosity = 0.36
An intense rain is falling at a uniform rate of 7.5 cm/hour for a period of 60 minutes on a basin whose area is 500 hectares. If the average infiltration capacity during the entire rain period is assumed to be 1.5 cm/hr, the maximum run-off rate based on 10 minute peak percentage of 16% from distributing graph of the basin, is 60 cumecs 100 cumecs 80 cumecs O40 cumecs
