Barrages Assignment Help
A barrage is a form of low diversion dam which is made up of variety of big gates which can be opened or closed to control the quantity of water passing through the construction. Therefore, modulate and stabilize river water level upstream to be used in other and irrigation systems. The gates are place between flanking piers in charge of supporting the water load of the pool. While the term, barrage is in use from the French word. Its use for this type of construction in English is primarily in other nations such as Middle East, Pakistan, India, Egypt, and Iraq.
As stated by the World Commission on Dams, an
important difference between a dam as well as a barrage is the fact that a dam is made for water storage in a reservoir which increases the level of water substantially.
The Barrage named Lloyd Barrage was constructed during the British Raj from 1923 to 1932. It was built under the general direction of Sir Charlton Harrison, CIE.
A barrage dam is a particular type of dam which is made up of line of big gates which can be opened or closed to control the quantity of water passing the dam. The gates are place between flanking piers that are in charge of supporting the water load. Stabilize and they are usually used to control water flow for irrigation systems.
Here are the names of the barrages:
1- Chashma Barrage
2- Taunsa Barrage
3- Jinnah Barrage
4- Kotri Barrage
5- Panjnad Barrage
6- Marala Barrage
7- Trimmu Barrage
8- Qadirabad Barrage
9- Sukkur Barrage
10- Khanki Barrage
11- Islam Barrage
12- Sidhnai Barrage
13- Sulmenaki Barrage
14- Balloki Barrage
15- Rasul Barrage
16- Guddu Barrage
Guddu Barrage is a barrage across river Indus near Sukkur in Pakistan. President Sikander Mirza set foundation-stone of the Guddu Barrage on February 2, 1957. The barrage was finished in 1962.
This is a gate controlled barrier kind barrage using a navigation lock. It feeds Begari Feeder, Ghotki Feeder, Desert and Pat Feeder canals.
It is situated on the Indus River which is the biggest river of Pakistan. The 66 gate barrage consists of iron and yellowish rocks. It was made specifically for the purpose of enhancing the irrigation system. Additionally, there is a museum called Sukkur Barrage Museum that has fascinating things in it and barrage model. The museum also gives the information about the barrage. Sukkur Barrage is the top attraction area for tourists.
HISTORY OF BUILDING OF BARRAGES
History of building of barrages Pakistan takes pride in its accomplishments in the building of many barrages. Historically, Pakistan has been designing and building barrages and barriers which have resulted in the state of the art present day knowledge.
Even before the development of the nation, the regions now included in Pakistan were undergoing developments to construct exceptional engineering works. The building of Khanki headworks was undertaken in 1890-92. The headworks of Rasul on Jhelum River were constructed in 1901.
In between 1950-52, three barrages were built on the Indus River at Kotri, Taunsa and Guddu.
Jinnah Barrage was built on River Indus with a maximum design discharge of 950,000 cusecs. In 1946, the total constructed withdrawal for canals is 7,500 cusecs. The barrage has 42 bays and each of them is 60 ft. broad. The span of the left reservoir is 5,487 feet and the right reservoir is of 4,099 ft. A low-head hydro power generation project is planned at Jinnah Barrage costing Rs. 9,882 million. Electricity will be generated by 8 units using a gross head of 16 feet.
Kotri Barrage was built on River Indus with a maximum design discharge of 875,000 cusecs. in 1955 The barrage has 44 bays, each 60 feet broad. The span of the right and left guide bank is ft. 6,000 Kotri Barrage was built to irrigate Pinyari Fulleli and Kolari canals through channels that were lined and improve agriculture in the lower Sindh area. The majority of specialists have, understood the necessity to release some quantity of water below Kotri Barrage, which is the last deflection point on the Indus River System. Also, any quantity of water discharged below Kotri would assist in assessing seawater invasion.
Taunsa Barrage was built on River Indus, 18miles downstream of Chashma Barrage in district Muzaffargarh in 1959. The barrage has a maximum design discharge of 750,000 cusecs. The total constructed withdrawal for canals is 36,501 cusecs. The barrage has 53 bays and each of them is 60 feet broad. The Taunsa-Panjnad Link was made to provide water to the Panjnad Headworks. In addition, it feeds the DG Khan and Muzaffargarh canals.
