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.

Water is drawn from an intake tower in Lake Ontario through a 3-km long precast reinforced concrete pipeline (Hazen-William’s C = 120) and delivered to the wet well of a low lift pumping station on shore which in turn supplies a water treatment plant. The pumping station is sized to deliver and will be operating at the maximum day flow rate of 2.65 m3/s. (a) If the design water elevation in the wet well is 70 m when the lake level is 74 m above MSL, determine the most economical pipe size for the intake (neglect local losses). (b) Compare the entrance and exit losses to the pipe friction losses to justify the assumption in (a). The entrance and exit loss coefficients can be assumed to be 1. (c) Sketch the hydraulic and energy grade lines. (d) Explain what would happen if the intake pipeline’s capacity was reduced but the pumping station is still operating at the same flow rate.
