A huge reservoir of constant water level feeds a wide channel of three reaches as shown in Figure P14.17. The first reach has a steep bed slope, the second has a mild bed slope, and the bed slope in the last one is adverse. The channel terminates into a free overfall. Two gates are located at the end of the first and second reaches, respectively. Assuming that the water level in the adverse reach is above the water level just before the second gate by 0.8 m, sketch the water surface profile.
