Spillway - Wikipedia
WebA spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water.
7 Different Types of Spillways - The Constructor
WebA spillway is a hydraulic structure built at a dam site for diverting the surplus water from a reservoir after it has been filled to its maximum capacity. Spillways are classified into different types on the basis of the arrangement of the control structure, a conveyance channel and a terminal structure.

WebSpillway, passage for surplus water over or around a dam when the reservoir itself is full. Spillways are particularly important safety features for several types of dams, protecting the dam and its foundation from erosion. Learn more about dam spillways with this article.
Spillway Definition & Meaning - Merriam-Webster
WebFeb 11, 2024 · The meaning of SPILLWAY is a passage for surplus water to run over or around an obstruction (such as a dam).
How Do Spillways Work? — Practical Engineering
WebMay 28, 2019 · Designing a spillway usually requires a team of engineers performing structural, geotechnical, electrical, mechanical, hydrologic, and hydraulic analysis to get it right. All so we can safely discharge water from a reservoir during high inflow events when there’s no more room to store it.

WebJan 15, 2024 · 1. Straight Drop Spillway. A straightforward solution for managing excess water, the Straight Drop Spillway features a low weir wall with a nearly vertical downstream face. As the water level rises, the surplus water freely falls from the weir crest. This spillway is suitable for thin arch dams, earthen dams, or bunds.
Spillway - Energy Education
WebA spillway is a structure constructed in a hydroelectric dam to provide a safe path for floodwaters to escape to some downstream area. Generally, the area that the spillway is released to is the river on which the hydroelectric dam was constructed. [2] . These spillways are an important functional part of a hydroelectric facility.
Spillway - an overview | ScienceDirect Topics
WebSpillways are facilities for conveying excess streamflows past a dam. In important projects on major rivers, spillways are sized to discharge extreme floods. At a concrete gravity dam, the spillway is typically made part of the main structure, providing an overflow that is either uncontrolled or regulated by gates (Fig. 12 ).
Spillway - an overview | ScienceDirect Topics
WebA spillway is a structure designed to ‘spill’ flood waters under controlled (i.e. safe) conditions. Flood waters can be discharged beneath the dam (e.g. culvert and bottom outlet), through the dam (e.g. rockfill dam) or above the dam (i.e. overflow spillway).
