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.
By general definition, a dam is a barrier that impounds water or underground streams, hence tailings dams are relegated to a separate list. Data on volume of structure is not as easily available or reliable as data on dam height and reservoir volume.
A head's location varies with the height of the water level against the dam. Since there is only an extremely low flow within the reservoir so no water level gradient, the head can be clearly seen: where the farthest watercourse discharges into the reservoir.
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 common primary functions of a barrage are: Increase the depth of a river (similar to a weir) Maintain a separation between fresh and salt water; Reduce the risk of tidal flooding up the river; Secondary functions may include: Tidal power generation; Artificial whitewater leisure centres; Form a Coastal reservoir
This dam slows a normally fast and shallow river for partial diversion to a hydroelectric dam. The diversion tunnel opening can be seen in the upper left. The Imperial Dam diverting the Colorado River in the southwestern United States. A diversion dam is a dam that diverts all or a portion of the flow of a river from its natural
An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes the dam impervious to surface or seepage erosion. [1]
