A dam is a barrier that stops or restricts the flow of water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. a barrier constructed to hold back water and raise its level, forming a reservoir used to generate electricity or as a water supply
DAMS IN PAKISTAN:
At this time there’re over one One hundred and fifty small and large dams and reservoirs in Pakistan. The majority of the dams and also reservoirs had built during 1960 and 1975. Based on the International Commission on Large Dams (ICOLD), total dams and also reservoirs in Pakistan over the height of 15 meters are 150. Here is the list of top 5 biggest dams in Pakistan.
1st biggest dam in the list is Tarbela Dam that’s situated on the Indus River and is also the largest earth filled dam in the world and is the 2nd largest by the structural volume. The dam is 148 meters high above the riverbed. Development started in 1968 and completed in 1976 at cost of $1,497 million. The total capacity of the dam is 13.69 cubic km spread over the construction area of 168,000 km2.
Next biggest dam in Pakistan is Mangla Dam that’s built in the Jhelum River in the Mirpur District of Azad Kashmir, Pakistan. It’s also the Ninth largest dam in the world. The development was started in 1961 and completed in 1967. It was constructed at the cost of $1.473 billion and also funded by the World Bank and Asian Development Bank.
Mirani Dam is yet another major dam in Pakistan. It is a medium-sized multi-purpose dam that’s situated on the Dasht River in Balochistan. In terms of volume for flood protection, it’s the largest dam in the world having bloodstock of 588,690 cubic hectometers. Its development began on July 8, 2002, and completed on October 2006.
Warsak Dam is a mass concrete gravity dam and located on the Kabul River north-west of the Peshawar city in Khyber Pakhtunkhwa. It was completed in 2 phases. 1st phase was completed in 1960 and the 2nd phase was finished in 1980-81. The total capacity of the Warsak Dam Hydropower Projects us 243 MW.
Sabakzai Dam is an embankment dam at Zohb River in Balochistan. The building of the dam started in 2004 and the irrigation works for the dam are still being built. Based on ICOLD, Sabakzai Dam is the Seventh largest in the world with a bloodstock of 23,638 cubic hectometers.
Diamer-Bhasha Dam is a concrete-filled gravity dam, in the preliminary stages of construction, on the River Indus in Gilgit-Baltistan in Pakistan. Its foundation stone was laid by Prime Minister [Yousaf Raza Gillani] of Pakistan on 18 October 2011. Upon completion, Diamer-Bhasha Dam would be the highest roller-compacted concrete (RCC) dam in the world. The dam site is situated near a place called “Bhasha” in Gilgit-Baltistan that’s why it is known as Diamer-Bhasha
Upon completion, Diamer-Bhasha Dam would produce 4,500 megawatts of electricity through environmentally clean hydropower generation, it stores an extra 8,500,000 acre-feet (10.5 km3) of water for Pakistan that would be used for irrigation and drinking , it extends the life of Tarbela Dam located downstream by 35 years; and can control flood damage by the River Indus downstream during high floods.
Dams are the great need for water savior and consumption of every country. though Pakistan consists of many dams still we need a number of the dam. the govt. of Pakistan is working on Diamer- Bhasha and they need donation for completion. we should give as much donation as we can.
