A 25-fr-high spillway is placed across a 20-fr-wide rectangular channel. The downstream channel is running on a slope of 0.000845 with an estimated Manning n value of 0.03. If the spillway is passing a discharge of 300 cfs,

a. What is the total depth of water behind the spillway? Assume a Cvalue of3.3.

6. Ignoring losses, what is the depth at the toe?

c. Will a hydraulic jump form downstream of the spillway, and, if so, what will be its conjugate depths?

d. Sketch the situation of chis problem, both upstream and downstream, being careful to label all of the profiles.
