An 8-foot wide rectangular channel carries 200 cubic feet per second of water at a depth of 1.5 feet before entering a hydraulic jump. The water depth downstream of the jump is most nearly: A. 2.4 ft B. 2.7 ft C. 3.4 ft D. 4.4 ft

A trapezoidal channel having a bottom slope of 0.001 is carrying a flow of 30 m/s.  The bottom width is 10.0 m and the side slopes are 2H to 1V.  A control structure is built at the downstream end which raises the water depth at the downstream end to 5.0 m.  Compute the water surface profile till 1.20 m.  Manning n is 0.013 and a = 1. Select an appropriate Month for your calculations.   Please read the question carefully and provide the correct solution with simple steps fast. Please answer quickly.

A rectangular channel is 3.0 m wide and carries a discharge of 3.3 m³/s at a depth of 0.9 m. A smooth contraction of the channel width is proposed at a section. Find the smallest contracted width that will not affect the upstream flow conditions. Neglect the energy losses in the transition.

1. Determine the depth (yo), bearing area (A), and wet circumference (P) of a trapezoidal shaped channel with the following known data mi = 2,5 m2 = 3,5 b = 5,5 m 1. mi Q = 24,5 m³/s m2 n= 0,014 So = 0,0003 %3D
