A 1-hr unit hydrograph for the No Name Creek watershed (307 acres) is given in the following table. Determine the stream flow that would result from a rainfall event on the same watershed if the excess rainfall (runoff) in a 2-hr storm in 30-min increments is 0.5 in., 0.5 in., 0.25 in., and 0.25 in. Assume a base flow of 10 cfs. Also determine the runoff volume in acre-feet.
