4) a) Uniform flow in a steep rectangular channel is interrupted by the presence of a hump in the channel bed which produces critical flow over it for a discharge of 4 m'/s. The channel properties are: b - 3 m, n= 0.015, So =0.01, Az = 0.083 m. Show that critical flow occurs over the hump. i. If the flow in the channel in part (a) above is suddenly reduced to 3 m/s some distance upstream, determine the new depth upstream of the hump and the speed of propagation of the surge wave formed.

A sluice gate in a 2.0 m wide horizontal rectangular channel is discharging freely. If the depths of a small distance upstream, y₁, and a downstream, y2, are 2.5 m and 0.20 m, respectively, estimate the discharge in the channel by 1) neglecting energy losses at the gate, and 2) by assuming the energy loss at the gate to be 10% of the upstream flow depth y₁. Ans: Dl Y₁ = 2.5 m y₂ = 0.2 m
