A trapezoidal channel made of unfinished concrete n = 0.014 has a bottom slope of 0.0174, base width of 5 m, and a side slope of 1:1. For a flow rate of 25 m3 /s, determine the normal depth and the state of the flow. Use Fr = v/(gD)0.5, where D is the hydraulic mean depth. (10 Marks)
Homework Answers
Therefore, Normal depth = 0.685 meters
And flow is in super-critical state

Water flows at 4 m3/s along a horizontal channel made of unfinished concrete (n=0.014). If the channel has a width of 2 m, and the water depth at the control section A is 0.9 m, approximate the depth at the section where x = 2 m from the control section. Use increments of Δd = 0.004 m and plot the profile for 0.884 m ≤ d ≤ 0.9 m.

A trapezoidal channel has a side slope of 1:1 and a bed width of 6.0 m. A hydraulic jump with a height of 0.5 m (i.e. the difference between water surface elevation upstream and downstream of the jump) is encountered in the channel. If the channel has a discharge of 10 m3/s, determine the critical depth in the channel. Plot the momentum curve and determine the flow depth immediately upstream and downstream of the jump.
