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.
The Fusegate blocks act as a fixed weir most of the time, but in excessive flood conditions they are designed to topple forward, allowing the controlled discharge of water. Multiple fusegates are generally set up side by side, with each fusegate designed to release under progressively extreme flooding, thus minimizing the impact of the ...
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.
Above the head of the reservoir natural conditions prevail; below it the water level above the riverbed has been raised by the impoundment and its flow rate reduced, unless and until banks, barrages, weir sluices or dams are overcome (overtopped), whereby a less frictional than natural course will exist (mid-level and surface rather than bed ...
Tasmania's Gordon Dam, one of the largest in Australia, was constructed in the 1970s. It has a catchment area of 1,280 km2 (494 sq mi). It has a catchment area of 1,280 km2 (494 sq mi). Dams and reservoirs in Australia is a link page for any dam or reservoir in Australia.

Durgapur Barrage and the canal network, was handed over to the Government of West Bengal in 1964. [5] In 1932, the Anderson weir was constructed at Randiha. As a result, irrigation facility has been available in the lower Damodar basin before the advent of dams by means of the diversion weir on the Damodar River and Eden canal. [6]
