A watershed is divided into sections as shown below. Runoff from each section will contribute to flow at gauge G as indicated in the table. For an excess rainfall intensity of 0.5 in/hr falling uniformly for 5 hrs, determine the resulting direct runoff hydrograph (DRO). 'D BCD A Area [ac] 150 250 350 200 Time to G [hr] 1 2 4 A G
