A trapezoidal concrete-lined spillway (b= 30 ft, m = 4) conveys 25,000 cfs down a steep slope(S = 5%) before a hydraulic jump to a downstream channel on a mild slope (S = 0.005%). State all assumptions and show all calculations when answering the following: a) Calculate the initial Froude number to confirm that a hydraulic jump is possible. b) A 10-ft deep stilling basin is constructed at the base of the steep slope. If the channel downstream of the stilling basin has the same dimensions as the spillway, estimate depth of hydraulic jump assuming basin is appropriately designed.
