What are the advantages of dams?

Advantages of Dams

• Water from dams is used for irrigation.
• 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.
• Dams prevent loss of life and property caused by flooding .
• Dams provide recreation around the area.

Are dams concave or convex?

Concrete arch dams are usually constructed of a series of vertical blocks that are keyed together; barriers that stop water from flowing are provided between the blocks. These dams have a convex curve into the reservoir to transfer water forces to the abutments.

Why are dams constructed?

Dams are built to provide water for human consumption, for irrigating arid and semiarid lands, or for use in industrial processes. Many dams are built for more than one purpose; for example, water in a single reservoir can be used for fishing, to generate hydroelectric power, and to support an irrigation system.

How are dams necessary for development of a country?

Dams have become an integral part of basic infrastructure by offering indispensable benefits like irrigation, hydropower, domestic and industrial water supply, flood control, drought mitigation, navigation, fish farming, and recreation.

What is the optimum shape of a concrete arch dam?

A novel and robust approach is proposed to \\fnd the optimum shape of concrete arch dams located on any unsymmetrical shape of a valley. The approach is capable of nding the optimum shape for any given valley type in suitable time, based on abutment stability analysis, against thrust forces from an arch dam.

What are the characteristics of a check dam?

Check dams not only slow water velocity but encourage ponding of water on the upstream side of each dam, hereby encouraging infiltration of stormwater; their design criteria: Should be a maximum of 18 inches in height and height should not exceed half the height of swale bank.

What is a dam used for?

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. See the Bonneville Dam in action.

What is an example of a dam body of water?

They can also be defined as the specific bodies of water formed by the construction of a dam. For example, the Hetch Hetchy Reservoir in California’s Yosemite National Park is the body of water created and held back by the O’Shaughnessy Dam.
