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.

Problem One: A trapezoidal channel of base width 20 ft and side slopes of 1.5H:1V is laid on a slope of 0.001, at a discharge of 1000 ft/s. Compute the flow and draw the surface profile upstream from the overfall to the region where the depth is 10 percent lower than uniform. Assume a manning n- 0.025 and that critical flow occurs at the overfall. Classify the profile.

water flows at a rate of 20 m3/s through a rectangular channel 4.0 m wide from a "steep slope" to a 'mild slope", creating a hydraulic jump. The upstream depth of flow is 1.20 m Find the following: (a) the downstream depth of flow, (b) the energy loss in the jump, anid (c) the upstream and downstream velocities 2)

(5) Water flows along a trapezoidal channel with base width B=1.5 m, side slope 1:1 (horizontal to vertical) and depth D=0.7 m. It is controlled downstream by a sharp crested weir that has a crest height of H=2.4 m above the channel bed and a crest width equal to that of the base width. Calculate the flow rate in the channel (check any assumptions you make).
