Stepped spillways, consisting of weirs and channels, have been used for over 3,500 years since the first structures were built in Greece and Crete.During Antiquity, the stepped-chute design was used for dam spillways, storm waterways, and in town water supply channels.
There are four main components of a chute spillway: [1] The elements of a spillway are the inlet, the vertical curve section (ogee curve), the steep-sloped channel and the outlet. In order to avoid a hydraulic jump , the slope of the spillway must be steep enough for the flow to remain supercritical.
Some varieties of flumes are used in measuring water flow of a larger channel. When used to measure the flow of water in open channels, a flume is defined as a specially shaped, fixed hydraulic structure that under free-flow conditions forces flow to accelerate in such a manner that the flow rate through the flume can be characterized by a level-to-flow relationship as applied to a single head ...
Chute spillway of Llyn Brianne dam in Wales. A 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 ...

The vertical hard basin drop structure, also called a dissipation wall, is the basic type of drop structure.The vertical hard basin drop consists of a vertical cutoff wall, usually built of concrete, that is usually laid perpendicular to the stream flow, and an impact basin, not unlike a stream pool, to catch the discharged water.
