A reservoir is a man-made lake where water is accumulate. Typically reservoirs are created by building dams across rivers. A reservoir can be made from a native lake whose outlet has been dammed to control the water level. The dam controls how much water that streams out of the reservoir.
It is stored only in a limited quantity of water that can be used later. This water can be used for domestic, industrial, and agricultural demands.
Changes in weather conditions make the regular progression of streams and rivers fluctuate extraordinarily with time. Times of an overabundance of streams and valley flooding might substitute with low streams or droughts. The job of water-storage reservoirs, subsequently, is to seize water during times of higher streams, in this way forestalling flood fiascos, and afterward grant the slow arrival of water during times of lower streams. Straightforward storage reservoirs were presumably made right off the bat in mankind’s set of experiences to give water to drinking and water systems.
Repositories normally are made by the development of dams across waterways, yet off-channel reservoirs might be given by redirection designs and trenches or pipelines that pass water from a stream onto regular or artificial depressions.
Why Reservoirs are Made? Purpose of a Reservoir
Peoples build reservoirs because the water level is not the same always in the river. In the rainy season, the water in a river rises and sometimes floods its banks. By restricting how much water is permitted to go on downriver, reservoirs assist with controlling flooding.
During droughts or broadened dry periods, the water level in a river might be extremely low. Under these circumstances, more water is set free from the repository so farmers can water their crops, and homes and organizations can work normally.
Reservoirs fill different needs. They are utilized for sailing, fishing, and different types of entertainment. A portion of the dams that make reservoirs is utilized to produce power.
Advantages of Reservoir
- A reservoir is used to irrigate crops.
- It is used to control the water flow in the river.
- It provides water supply to the local community.
- A reservoir can also supply a limited amount of water to industries.
