Water flows within the 4-m-wide rectangular channel at 25 m3/s. Take yA = 0.4 m. Part A Determine the depth of flow yB at the downstream end. Part B Determine the velocity of flow at A.
Water flows in an open rectangular channel at a depth of 1 m with a velocity of 4 m/s.
4.72) Water flows in an open rectangular channel at a depth of 1 m with a velocity of 4 m/s. The bottom of the channel drops over a short length a distance of 1 m. Calculate the two possible depths of flow after the drop. Neglect all losses. 4.73) If the head loss in Problem 4.72 across the channel drop is 0.2 m, determine the two possible depths of flow.

2. A 2.5 m wide rectangular channel conveys m wide rectangular channel conveys water at a normal depth of 2 m. In a part of the channel, the channel width is expanded to 5 m. The local energy loss due to this expansion is about 10% of the upstream velocity head. If the channel slope is 0.03% and the Manning roughness coefficient is about 0.012, calculate the water depth over this transition and show the situation with a simple sketch.

A canoer is aimlessly paddling in the 15 m wide rectangular channel downstream of a dam. The water depth and discharge in the channel are 5 m and 175 m3/s respectively. The dam operator assumes that the channel is clear, and ‘instantaneously’ ramps up the discharge to 210 m3/s, creating a surge that moves downstream. If the canoer is 350 m downstream of the surge at the instant that the surge is created and is able to paddle 1.5 m/s more than the speed of the water below him, will he make it to the dock that is 175 m downstream of him before being hit by the surge?
