In a trapezoidal channel with a constant width of b=3 m. and side slopes of 1:3 (1 vertical, 3 horizontal) and discharge rate of 6 m3 /sec, if the maximum step upward height is z=0.5 m. not to cause any choking, what is the water depth before and after this maximum step upward. Draw the water surface profile and specific energy curve (E vs y) for this flow.
