Troopers: ATV rider found dead in tributary of Knik River

SOLVED: For the part of a city in the layout below, design the storm sewer system (may use excel software). Assume the following conditions:1. The tributary area and ground surface elevations are given in the figure.2. The runoff coefficients are given in the figure.3. The design frequency is 2 years, in which the rainfall intensity (in/hr) is given by 4 in/hr.4. Manning's coefficient n = 0.013.5. Q in partially full condition with y/D = 0.7.52C = 0.4C = 0.690-C = 0.36465.0 130m 19km C = 0.364.7
