Water is flowing in a channel that can be approximated as a rectangular section 250 ft wide with a discharge of 10,000 cfs. A 100-ft-high spillway is erected across the channel with a Francis C value that is calibrated to be 3.25 (with reference to the actual head on the crest).

a. To what depth will the water rise behind the spillway?

b. What will be the theoretical velocity at the toe of the spillway?
