Water flows at 11 m3/s in a rectangular channel of width 5 m. The slope of the channel is 0.001 and the Manning roughness coefficient is equal to 0.035. If the depth of flow at a selected section is 2 m, calculate the upstream depth at 500 m from the selected section using the standard step method
The figure below shows a channel with an overflow dam section in place. The depth just upstream of the dam is 3.0 metres, . The energy grade line at the dam is located 1.125 m above the crest of the dam. The channel slope is 0.001, Manning's roughness coefficient is 0.02, and the width of the rectangular channel section is 5.0 m.

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.
Water flows in a rectangular channel with a velocity of 2.5 m/s and a depth of 1.5 m. A door downstream suddenly closes completely, causing surge move to upstream. Determine : a) Velocity Surge(w) b) The depth behind the surge (y2)
Water flows steadily along a horizontal open channel of uniform width, over a broad-crested weir. The channel bed upstream from the weir (to the left) is d -0.75m above the channel bed downstream from the weir (to the right), as shown in the figure below. The volume flow rate per unit width is Q 6m2 s-1, and the downstream depth of the water is ћ2-d. Take the magnitude of the acceleration due to gravity as g 10ms-2. d - 0.75...
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)
Water flows down a rectangular channel that has a width of 2.2 m, a Manning's n of 0.019 and a slope of 1 in 200. Calculate the discharge in the channel when the depth of flow is 0.5 m, 1.0 m, 2.0 m, and 4.0 m. Plot a graph of depth against discharge and comment on its shape, [10 marks] A wide channel has a Manning's number = 0.021, a longitudinal bed slope of 1:250 and conveys 0.XX m3/s/m of...
Supercritical, uniform flow of water occurs in a 5.0 m wide, rectangular, horizontal channel. The depth of flow is 1.5 m and the flowrate is 45 cu.m/s. The flow encounters a 0.25 m rise in the channel bottom. What is the new normal depth? Is the flow after the rise subcritical, critical or supercritical? Assume frictionless flow
