A trapezoidal channel with a bottom width of 5m and side slope of 1V:2H is constructed to convey a steady discharge to a hydropower installation. This is made up of concrete with a Manning's n = 0.016 and bed slope of 3V:2000H. a. Determine the discharge and velocity if the discharge has a 2m-depth of water? b. Calculate the depth if discharge is 35m³/s? c. As shown below, when flooded, the flow goes over the top of the channel. If the flood channels are 10 m. wide and with side slopes of 1V:3H, and roughness is n=0.035, what is the discharge for a flood level of 4m? 14.5 15.0 14.5 region 2 region 1 4 region 3 3 10 10 5 2.
