Water storage in dams

• Dams are used to store water.
• Water is stored as a reservoir behind the dam.
• Dams are constructed on a river, and they work as an obstruction for the water of the river flowing downwards.
• Thus, creating a reservoir behind the dam storing water.

Watershed

• The water stored in the dam can be used for various sources.
• It can be distributed to industries, to farms and households and any other area where the basic and important requirement is water.

Electric Power Generation

• the electricity produced by the water stored in the dam is called hydroelectric power.
• The water in a dam is stored at a height i.e., almost equivalent to the height of the dam.
• The water at this height has some potential energy.
• When the dam is opened, the potential energy is converted to kinetic energy and there are meters that this running water having a great energy rotates.
• In this way electrical energy is produced with the help of hydro energy of water.
