The trapezoidal channel has a slope of .004. The sides of the canal are sealed with a plastic membrane, which is protected by a 1 ft thick layer of 1 in diameter gravel. The bottom is a 6 in slab of rough concrete. If the water is flowing at a uniform depth of 6 ft, do you think the gravel will be scoured by the flowing water? Justify your answer by appropriate calculations.
