A barrage dam can be used to divert water for irrigation needs or limit the amount of water downstream. In most cases, a barrage dam is built near the mouth of the river. The site of dam construction needs to be thoroughly investigated to ensure that the foundation is strong enough to support the dam and has low possibility of failing. [2]
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 Lower Chenab Canal originates from the Barrage carrying about 11,600 cusecs of water. The weir originally was a shuttered type weir comprising 8 spans of 500 ft each and was first one in Punjab which was built upon alluvial soil. The weir got repeatedly damaged in portions and had to be remodeled extensively during 1919-1920 and 1933–1935.
A polynomial weir is a weir that has a geometry defined by a polynomial equation of any order n. [11] In practice, most weirs are low-order polynomial weirs. The standard rectangular weir is, for example, a polynomial weir of order zero. The triangular (V-notch) and trapezoidal weirs are of order one. High-order polynomial weirs are providing ...
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]

The Bhimgoda Barrage, also referred to as the Bhimgoda Weir or Bhimgoda Head Works, is a barrage on the Ganges River at Har ki Pauri near Haridwar in Haridwar district, Uttarakhand, India. Built as the headworks of the Upper Ganges Canal , an initial barrage was completed by 1854 and replaced twice; the final one completed in 1983.
Diyala Weir, also known as the Diyala Barrage, is a diversion dam on the Diyala River 90 km northeast of Baghdad, Iraq.It was constructed between 1966 and 1969. The main purpose of the dam is to divert outflow of the Hemrin Dam (11 km upstream) on the Diyala River to the Khalis and Sadr Al-Mushtarak canals for irrigation.
