Abstract
Huff rainfall temporal distributions published in Atlas 14 are contrasted with rainfall distributions with nested intensity-duration-frequency functions that are also derived from Atlas 14, and the role of Huff rainfall distributions in the design of stormwater-management systems is assessed. Results show that Huff distributions generally underestimate average rainfall intensities for shorter-duration time intervals, which makes them not acceptable for designs based on peak runoff rates. In the design of detention basins to control site discharge rates for a given return period, the results show that in many cases conventional detention-basin designs based on nested rainfall distributions will perform inadequately in response to the more realistic Huff rainfall distributions. Overall, the results indicate that Huff rainfall distributions should be incorporated in sizing detention basins to ensure that peak postdevelopment discharges do not exceed peak predevelopment discharges for given design return periods.
