Estimate the new water depth upstream

Reference no: EM131151529

A clean earth river is 50 ft wide and averages 600 ft3 /s. It contains a dam that increases the water depth to 8 ft, to provide head for a hydropower plant. The bed slope is 0.0025.

(a) What is the normal depth of this river?

(b) Engineers propose putting flashboards on the dam to raise the water level to 10 ft. Residents a half mile upstream are worried about flooding above their present water depth of about 2.2 ft. Using Eq. (10.52) in one big half-mile step, estimate the new water depth upstream.
