A catchment in Starkville consists of an asphalt pavement that drains into a rectangular concrete channel. The asphalt surface (n 0.012) has an average slope of 0.6% and the distance from the catchment boundary to the drain is 165 ft. The concrete drainage canal (n-0.013) is 100 ft long. 0.8 ft wide and 0.7 feet deep and has a slope of 0.8 %. For an effective rainfall (2 yr 24 hour rainfall) of412 in the flow rate in the channel is estimated to be 1.0 cfs.
