Hope your help hydraulic CEE 340

Problem VI: A 100-ac undeveloped watershed (including 5-ac swamps) in Iowa has a composite
CN = 50. Its 2-year 24-hr storm has a rainfall depth of 2.95 in. 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 ft, and flow path slope of 0.001), shallow concentrated flow (flow path length of 80
ft and flow path slope of 0.005), and wide-shallow channel flow (Manning's n of 0.035, bank-full
depth of 1.2 ft, channel length of 1000 ft, and bed slope of 0.008). If the watershed has a time of
concentration of 36 min, determine the peak discharge from a 24-hr storm with a 5.0 in rainfall
using the TR-55 Graphical Peak Flow method.
