2. Water flowing at the normal depth in a rectangular concrete channel that is 12 m wide encounters an obstruction, causing the water level to rise above the normal depth at the obstruction and for some distance upstream. The water discharge is 126 m3/s, and the channel bottom slope is 0.00086. If the depth of water just upstream from the obstruction (yo) is 4.55 m, find the distance upstream to the point where...

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.

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...

Please give detailed
solution
A long rectangular unfinished concrete channel of width 3.6 m carries a flow of 14 m/s, with an abrupt change in slope from 0.0019 to 0.0180 at the midpoint of the channel. Determine: a) the uniform flow depths upstream and downstream of the change in slope, b) the critical flow depth, and c) the water surface profile types upstream and downstream of the change in slope.

Water flows at 4.3m/s in a rectangular channel of width 3 m and depth of flow 1m. If the channel width is decreased by 0.75m and the bottom of the channel is raised by 0.25m, Find the followings: The discharge per unit width before the constriction q m3/s/m Discharge per unit width at the constriction q" = m/s/m Water depth of flow in the constriction y2 =

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 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
