Question

There is a dam with a maximum water depth of 50 ft. Initially, the downstream river has a negligible velocity and a depth of 5 ft. Neglect bed slope and resistance effects. Gravitational acceleration g = 32.2 (ft/s2). (a) (15 points) Determine the speed of the surge after the dam fails abruptly. (b) (5 points) Estimate the time required for the surge to reach a community 5 mi downstream of the dam.
