The trapezoidal channel carrying a discharge of 100 m3 /sec. The bed of the channel descends at the rate of unit m per 5000 ft. The side slope is 2H to 2V on right bank and left bank. Where, the bottom width is 25 m. A dam is built at the downstream side which raises the water depth at down-stream end to 8 m. Compute the normal depth, critical depth and the water surface profile by Direct Step Method. Where Manning's n = 0.025 and a = 1. If we assume the same discharge occurs in triangular channel with same side and bed slope, what would be its effect on normal depth, critical depth and water surface profile
