Water is flowing in a trapezoidal earthen channel with bottom width 2 m and side slopes 1.5 Hf 1 V The channel is carrying a discharge of 50 m3 /s and is running on a slope of 0.0025 m/m. If the roughness coefficient is 0.030, what is the normal depth in the channel?

A 3-m-wide rectangular irrigation channel carries a discharge of 25.3
/s at a uniform depth of 1.2 m. Determine the slope of the channel with n = 0.022. If the discharge is increased to 40
 /s, what is the normal depth of flow?
