Question

1. A long trapezoidal channel with a roughness coefficient of 0.015, bottom width measuring 4.0 m, and m = 1 carries a flow rate of 50 m³/sec. An obstruction is encountered in the channel that rises the water depth to 5.0 m. The channel slope is 0.00 Compute the depth of water surface at a distances 100 m, 200 m, 300 m, 400 m and 500 m.

Channel slope is 0.001
