A dam is a structure built across a stream or river to hold water back. Dams can be used to store water, control flooding, and generate electricity.Feb 27, 2013
What is the main purpose of the dam?
The purpose of a dam is to impound (store) water, wastewater or liquid borne materials for any of several reasons, such as flood control, human water supply, irrigation, livestock water supply, energy generation, containment of mine tailings, recreation, or pollution control.

What is dam Short answer?
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability.
What dams explain?
A dam is a structure built across a river or stream to hold back water. People have used different materials to build dams over the centuries. Ancient dam builders used natural materials such as rocks or clay. Modern-day dam builders often use concrete. Manmade dams create artificial lakes called reservoirs.
How are dams useful for agriculture?
Dams can help increase agricultural production by controlling the supply of irrigation water to crops, protect production from climatic risk, help generate electricity, and reduce the risk of potentially disastrous river floods.
Why do dams need to release water?
During times of excess water flow, dams store water in the reservoir; then they release water during times of low flow, when natural flows are inadequate to meet water demand. When engineers design and maintain dams, they consider all these purposes.
What is flood simple words?
A flood is an overflow of water that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health.
