Concept explainers

Spillway design

A spillway is the overflow portion of the dam that carries the surplus discharge flow from the reservoir to the downstream, that is, it carries the flood water safely downstream, which is enough to be stored in that reservoir. Therefore, it acts as a safety valve for the dam because many failures of the dam arise due to the incorrect design of the spillway.

An aquifer slopes away from a river, as shown in Fig. 3-7 The hydraulic conductivity of the aquifer which is 20 ft thick is known to be 0.2 ft/day. The water is 20 ft deep in the river, and the bottom of the trench is 30 ft below the bottom of the river and 600 ft away from the edge of the river. The trench is 40 ft deep. Will water flow out of the trench without pumping? If so, what will be the rate of flow?
