What is a dam and why is it built?

What are the reasons for creating and building dams?

The most important task of these structures is to collect water behind their walls, which can solve many problems. Provision of drinking water for humans, irrigation of agricultural lands, control of floods and supply of potential energy for electricity production are among the most important reasons for creating these structures.

Of course, after the construction of these structures, the lake behind it can be used in various ways, such as canoeing, fish farming, and creating natural promenades, etc.

In fact, these dams stand in front of a huge amount of water and stop and restrain them. With this stoppage of water, a lake is formed behind these dams, which are called reservoirs. The purpose of creating these tanks is to collect water so that they can be used when needed.
