A barrage is a type of low-head, diversion dam which consists of a number of large gates that can be opened or closed to control the amount of water passing through. This allows the structure to regulate and stabilize river water elevation upstream for use in irrigation and other systems.
A barrage dam is a special kind of dam that consists of a line of large gates that can be opened or closed to control the amount of water passing the dam. The gates are set between flanking piers which are responsible for supporting the water load, and are often used to control and stabilize water flow for irrigation systems.
A tidal barrage is a dam-like structure used to capture the energy from masses of water moving in and out of a bay or river due to tidal forces. [ 1 ] [ 2 ] Instead of damming water on one side like a conventional dam , a tidal barrage allows water to flow into a bay or river during high tide , and releases the water during low tide .
The following table lists the largest man-made dams by volume of fill/structure. By general definition, a dam is a barrier that impounds water or underground streams, hence tailings dams are relegated to a separate list.
Barrage (military science), a wide range of structures, devices, or measures for destroying something to constrain or impede the movement of troops and forces. Barrage (artillery), a line or barrier of artillery or depth charge fire; Barrage (dam), a type of dam; Barrage balloon, a tethered balloon used as an obstacle to attacking aircraft
A weir / w ɪər / or low-head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs.
Depending on the flow rate and control of the barrage, locks or weir, position will greatly vary and will not necessarily be where the so-called headworks are. Many rivers (such as the Moselle ) are barraged many times to make them navigable and/or to avoid uncontrolled flooding.
