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 12-ft-wide rectangular channel conveys 3,030 cfs. Determine the normal and critical depths for the concrete channel (1% slope). Also determine the flow classification (critical, supercritical, or subcritical) when the channel flows at normal depth.

(b) Determine the normal depth if the channel has a flow rate of 2.85 m3/s. (c) Determine the cross section of greatest hydraulic efficiency for a trapezoidal channel if the design discharge is 10 m3/s, the channel slope is 0.0052 and manning’s n = 0.025.
Q4. Determine the normal depth (Using the Design Curves and the Trial and Error Methods) and critical depth (Using the Trial and Error Method) in a trapezoidal channel with a bottom width of 40 ft, side slopes of (3H:1V) and a bed slope of 0.002 ft/ft. The Manning's n is 0.025 and the discharge is 3000 cfs. (25 points).
02) A long rectangular channel is 3 m wide with Manning roughness of 0.018 and bottom slope of 2%. The channel runs downstream from a reservoir into a free overfall at its end. In the reservoir the water surface level is 1.35 m above the bed of the channel at the entrance. Ignore local loss at entrance. a) Calculate the critical depth, the discharge and the normal depth of the channel. (5/8) b) Sketch the water surface profile in the...
A rectangular river channel 5.0m wide carries water at a depth of 1.2m. The slope of the channel is 1 in 400. The channel has a bed covered with stones. Using the n value of 0.03(s/m1/3) calculate the discharge in the channel using Manning’s equation
An 8 ft. wide and 1000 ft. long prismatic rectangular channel is carrying a flow of 13 cfs. The channel has a slope of 0.001 ft/ft and Manning's n is 0.035. The depth of water in the channel is 1.25 ft. a. Another engineer computed the normal depth in the channel to be 1.25 ft, which is the existing depth of flow. Check that computation to see if it correct (show all work) b. Compute the critical depth of flow in the...
