Solve for and sketch the water surface profile in a very long 10ft wide rectangular open channel of rough brickwork (n=0.017) when the flow rate is 400cfs. The bed slope is 0.02, and a 5 ft high streamlined hump is at downstream end. Locate all hydraulic jumps treating any gradually varied flow as a single reach. How does the water surface elevation vary between key points?

Water flows in a rectangular concrete channel that is 10 m wide and has a slope of 0.005. The depth of the uniform flow in the channel (y1) is 450 mm and the discharge per width of the water is 2.2 m2/s. The downstream channel is smooth, and a hydraulic jump is forced to form in the channel by installing a sill. Calculate: (i) the depth and velocity of the water downstream of the hydraulic jump; (ii) the difference in...

A very long rectangular channel has a b =5 ft, S = 0.001 and n = 0.015. The steady state flow rate is 250 cfs. This reach is connected to a steep reach on the downstream end. What is the point of control? Is the flow supercritical or subcritical? Calculate the water surface profile using the direct step procedure. What is the length of the channel?

A long rectangular concrete channel (b = 10 ft, n = 0.015) carries 400 cfs. There is a grade break in the channel; the slope upstream of the grade break is 0.02 and the slope downstream of the grade break is 0.002. The following equations are valid for a rectangular channel: • DC = [(Q2)/(g*b2)]1/3 • y2 = 0.5*y1*[(1+8NFr12)1/2 -1] (for hydraulic jump) • NFr = v/(g*y)1/2 a) Use calculations to classify each section of the channel (steep, mild, horizontal,...
