Design a rectangular riprap channel to convey 30 cfs with a velocity of 2.5 ft/sec. Use the high end of the n-value for riprap. The slope is 0.5 percent. Solve analytically, i.e., set up equations for properties (area, wetted perimeter, and hydraulic radius) and solve for the unknowns. Then check. No credit if analytic solution is not included

Design a rectangular riprap channel to convey 30 cfs with a velocity of 2.5 ft/sec. Use the high end of the n-value for riprap. The slope is 0.5 percent. Solve analytically, i.e., set up equations for properties (area, wetted perimeter, and hydraulic radius) and solve for the unknowns. Then check using a spreadsheet.

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,...
