5.22. A trapezoidal channel is to be excavated on a slope of 0.1% and have a design discharge of 35 m³/s. Right-of- way constraints require the top width of the channel to be 17 m, and the channel is expected to consist of clean gravel (moderately angular) with a 75-percentile diame- ter of 3 cm. If freeboard is taken to be zero, determine the required bottom width and side slopes of the chan- nel. Is the required channel practical?
