'. (a) Compute the runoff from a 7-in rainfall on a 1500-acre watershed that has hydrologic soil groups that are 40 percent group A, 40 percent group B, and 20 percent group C interspersed throughout the watershed. The land use is 90 percent residential area that is 30 percent impervious, and 10 percent paved roads with curbs. Assume AMC II conditions. (b) What was the runoff for the same watershed and same rainfall before development occurred? The land use prior to development was pasture and range land in poor condition.
