Question

Hope your help hydraulic CEE 340

**Problem VI:** A 100-acre undeveloped watershed (including 5-acre swamps) in Iowa has a composite CN = 50. A 2-year, 24-hour storm has a rainfall depth of 2.95 inches. From the remotest location to the watershed outlet, the overland runoff goes through sheet flow (Manning’s n of 0.25, flow path length of 50 feet, and flow path slope of 0.001), shallow concentrated flow (flow path length of 80 feet and flow path slope of 0.005), and wide-shallow channel flow (Manning’s n of 0.033, bank-full depth of 1.2 feet, channel length of 1000 feet, and bed slope of 0.008). If the watershed has a time of concentration of 36 minutes, determine the peak discharge from a 24-hour storm with a 5.0-inch rainfall using the TR-55 Graphical Peak Flow method.
