What is dam and uses of dam?

dam, structure built across a stream, a river, or an estuary to retain water. Dams are built to provide water for human consumption, for irrigating arid and semiarid lands, or for use in industrial processes.

What are the uses of dams Class 10?

Advantages of Dams Water from dams is used for irrigation. Dams make sure water is available for crops throughout the year. Water from Dams is treated and distributed in nearby towns and cities for drinking purposes. Dams are used to generate Electricity through Hydro Electric Power.

How can Dams help?

Dams are important because they provide water for domestic, industry and irrigation purposes. Dams often also provide hydroelectric power production and river navigation. Dams and their reservoirs provide recreation areas for fishing and boating. They help people by reducing or preventing floods.

What are dams Class 5?

A dam is a barrier across flowing water which hamper, directs or reduces the flow of water. Dams and reservoirs can be effectively used to control floods by regulating river water flows downstream the dam. Electricity produced by utilising the falling water of a dam is known as hydro electricity.

How do dams cause floods?

What’s more, over five times this area is considered prone to floods, caused when rivers breach their banks. But this year, and of late, it’s not just heavy rains, but the operation of dams that have induced floods, when water released from a dam reservoir is beyond the carrying capacity of channels downstream.

How can dams can cause floods?

How does a flood dam protect against floods?

Dams protect against flooding by collecting and holding waters when they reach a certain level. Once collected, a dam might be designed to release the water back into the river at a controlled speed or divert the water elsewhere for other uses. One example of this is a flow-through dam, also known as a perforated dam.

How do draindams protect against floods?

Dams protect against flooding by collecting and holding waters when they reach a certain level. Once collected, a dam might be designed to release the water back into the river at a controlled speed or divert the water elsewhere for other uses.

Why are dams built at the same level as the river?

Because this type of dam is built solely for flood control, the opening (spillway) is at the same level as the riverbed. This means that when there isn’t excess water, the river will continue its natural flow.

What is the purpose of flood control?

Flood Control. For centuries, people have built dams to help control devastating floods. It helps to prevent the loss of life and property. Flood control dams impound floodwaters and then either release them under control to the river below the dam or store or divert the water for other uses.
