A trapezoidal channel of 5.0 m bed width and 3: 2 side slope carries a discharge of 16.0 m3 /s. Find the critical depth. The channel exhibits changes in the bed slope in three reaches. Normal depths of flow are 1.2 m, 0.7 m, and 0.94 m, respectively. A gate is located in the midway of the second reach. D raw the water surface profile.
