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.

Question

Q2: A spillway needs to be designed to carry a peak flow of 50m'/is with the reservoir elevation Im above
the crest of the spillway. The elevation difference between the reservoir and the tail water is 15m. If an
overflow spillway is used, with a discharge coefficient of 2.0, determine the length of the spillway crest
required to handle the discharge. Also determine the discharge coefficient in British unit.

Find the discharge through a 6” round orifice discharging freely. The water surface elevation in the impoundment is 568’. The elevation at the center of the orifice is 500’. Use a discharge coefficient of 0.62.
The outflow rate (O) and storage (S) for the emergency spillway are linearly related as O = S/10,000. Where, O andS are respectively in m3/s and m3. Based on the assumption that at the beginning (i.e., time = 0.0 hour), the storage,the inflow rate, and the outflow rate are all equal to zero; determine the outflow rate from the reservoir at the endof 2 hours period if the inflow rate is 500 m3/s.
Assume you have the channel reach shown that is mild (dn>dc); calculate the upstream and downstream depths of the hydraulic jump (note there is a hydraulic jump because upstream there is a gate controlling the water to below critical.

A 7350 m long, 1050 mm concrete pipeline connects an upstream reservoir (watersurface elevation 433.3 m) to a downstream reservoir (water surface elevation 423.1 m). Adischarge valve at the downstream end is used to control flow; when this valve is fully open,the measured discharge in the pipeline is 920 L/s under the naturally available head difference.(a) Assuming fully developed turbulent flow and that all other local losses are negligible,estimate the loss coefficient k for the fully open valve (assume f = 0.015).(b) Because of increasing urban development, the flow under the natural head difference isconsidered to be inadequate and it is proposed to increase this flow with pumping. The head-capacity curve for the pump can be approximated by the equation H = 8 – 3.5Q2 in which H isthe total dynamic head on the pump (in m) and Q is the discharge (in m3/s). What is thedischarge that can now be obtained from the system where the pump is installed at a cross-section of the pipeline?

You need to design a hydraulic jump in a channel downstream of a gate. A total flow of 396 cfs is moving through a concrete rectangular channel. The width of the channel is 17 ft wide. The flow depth of flow in the upstream reach of the channel is 1.55. Calculate the depth of flow downstream
