Rainfall rates for successive 20-min periods of a 140-min storm are 1.5, 1.5, 6.0, 4.0, 1.0, 0.8, and 3.2 in/hr, totaling 6.0 in. Determine the rainfall excesses for successive periods by the Green-Ampt model and then report the cumulative storm runoff [in] below. Assume a saturate hydraulic conductivity of 0.8 in/hr, a porosity of 0.62, an initial moisture content of 0.28, and an average capillary suction of 7.2 in. The depression storage is 0.5 in.
