Determination of Discharge Capacity and Number of Spillways

The maximum discharge capacity and the number of spillways are determined by studying the following factors: By studying the flood hydrograph of past ten years, the maximum flood discharge may be computed which is to be disposed off completely through the spillways. The water level in the reservoir should never be allowed to rise above the maximum pool

Parameters considered in Designing Spillways

The topography, hydrology, hydraulics, geology and economic considerations all have a bearing on these decisions. For a given inflow flood hydro graph, the maximum rise in the reservoir level depends on the discharge characteristics of the spillway crest and its size and can be obtained by flood routing. Trial with different sizes can then help in getting the optimum combination

Spillway Control Devices - FlashBoards and Stop Logs

The simplest form of control for a spillway is the free, or uncontrolled, overflow crest, which automatically releases water whenever the reservoir water surface rises above crest level. The advantages of the uncontrolled crest are the elimination of the need for constant attendance and regulation of the control devices by an operator and the freedom from maintenance

Spillway - Definition, Types and Classification of Spillway

There are different types of spillways that can be provided depending on the suitability of site and other parameters. Generally a spillway consists of a control structure, a conveyance channel and a terminal structure, but the former two may be combined in the same for certain types. The more common types are briefly described below: Drop, Ogee, Siphon Chute,

Cross Sectional Design of Typical Side Channel Spillways

The side channel design is concerned only with the hydraulic action in the upstream reach of the discharge channel and is more or less independent of the details selected for the other spillway components. Flows from the side channel can be directed into an open discharge channel or into a closed conduit or inclined tunnel. Flow into the side channel might enter the trough
