C. Ravi
D. Sutlej
Correct Answer Is Option = Jhelum
Notes / Explanation
The Mangla Dam is built on the river Jhelum, and it is one of the largest dams in the country, serving important purposes connected with the storage of water, the generation of electricity and the control of floods. The Jhelum is one of the important rivers of the country and one of the tributaries that join the great river system on which the country depends. A dam is a great barrier built across a river to hold back the water and to create a large reservoir behind it, and the Mangla Dam, built across the Jhelum, creates a large reservoir that serves the country in several important ways. One of its most important purposes is the storage of water, for the reservoir behind the dam stores a large quantity of water during the times when the river is full, and this stored water can then be released as needed, particularly during the drier times of the year, to provide a steady supply of water for the irrigation of the agricultural lands of the country. The dam also plays an important role in the generation of electricity, for the force of the water released through the dam is used to produce a large amount of hydroelectric power, which is added to the national supply and helps to meet the country's need for electricity. The dam also helps in the control of floods, by holding back excess water during times of high flow. The Mangla Dam is therefore of great importance to the country, contributing to its agriculture, its supply of electricity and its protection against floods, in the same way as the other great dams of the country. Together with the Tarbela Dam on the Indus and the other dams, barrages and canals of the country, the Mangla Dam is part of the great system of water management on which the agriculture, the water supply and the generation of power of the country depend. The building of such great dams is a major undertaking of great importance to the development of the country. The study of the important dams and rivers of the country is a part of the geography of the country. For PPSC and other competitive examinations, the key points to remember are that the Mangla Dam is built on the river Jhelum, that it is one of the largest dams in the country, that it serves the important purposes of storing water for irrigation, generating hydroelectric power and helping to control floods, and that it is part of the great system of water management on which the country depends.
