It is desired to design a trapezoidal channel to carry a maximum discharge of 1770 cfs through an alluvium on a slope of 0.002 ft/ft and with an angle of repose of 30°. Conditions are such that the optimum lining will be Bermuda grass with an average height of 6 cm. Determine the channel dimensions for the canal to meet these requirements.
