The outflow from a reservoir is to be controlled by the SCS drop inlet as shown in the sketch below. The design discharge is 450 cfs and the rail-water elevation is 10 ft as shown. If the top of the embankment is 42 ft and the water level is not to get higher than 2 ft below the top, design the riser and RCP to achieve the desired result.
