Chute spillways carry supercritical flow through the steep slope of an open channel. 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.
This design allows nearly the full height of the dam to be used for water storage year-round, and flood waters can be released as required by opening one or more gates. An uncontrolled spillway, in contrast, does not have gates; when the water rises above the lip or crest of the spillway, it begins to be released from the reservoir.
Although the stepped spillway design was common up to the beginning of the 20th century, a lot of expertise has been lost since, and the present expertise is limited to very simple geometries, namely some flat, horizontal, stepped prismatic chutes, despite some recent interest in stepped spillway design.

A demonstration of a fire escape chute on the streets of Daegu, South Korea.. An escape chute is a special kind of emergency exit, used where conventional fire escape stairways are impractical.
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.

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 ...
