Question: A very wide rectangular channel carries a discharge ( q ) of 1 0 . 0 m 3 / s / m on a slope

A very wide rectangular channel carries a discharge (q) of 10.0 m3/s/m on a slope of 0.001 with an n value of 0.026. The channel ends in a free outfall. Compute the distance required for the depth to reach 0.9y0 using the direct step method.
