Adischarge of 2, 200 ft^3/sec flows in a trapezoidal channel at a normal depth of 8.0 ft. the channel has a slope of 0.01, a 12 ft bottom width, and side slopes of 1: 1 (h: v). determine the manning coefficient of channel roughness. also determine the sensitivity range of the roughness coefficient estimate if the flow rate can only be estimated to within ±200[cfs].
