$\bf{\underline{\underline \blue{AnswEr:-}}}$

Dams are built on rivers to hold back the water in a reservoir behind the dam. The reservoir fills up during the monsoon months. This controls floods in the rivers. This water is used for irrigation during the time when there is no shortage of water.

The force of the water as it flows down from the reservoir, is used to generate electricity electricity generated from the force of water is called hydroelectricity. Since dams are useful in so many different ways, they are called multipurpose projectors.
