A 25-ft-high spillway is placed across a 20-ft-wide rectangular channel. The slope of the spillway face is 1 V/ 4H The downstream channel is running on a slope of 0.000845 with an estimated Manning n value of 0.03. If the head on the spillway is measured to be 3 ft and the C value is 3.1,

a. Assuming losses on the spillway face will be

what is the water depth at the spillway toe?

b. Will a hydraulic jump form downstream of the spillway, and, if so, will it occur right at the toe or run? c. If there is a jump, what would be its conjugate depths?
