One of the purpose of this reservoir is to Generate electricity. The electricity generated by use of water ( Hydro) is known as Hydro Electricity.
Benefits of Dams
- Dams helps to generate electricity. This electricity is then distributed to various areas.
- The reservoir of Dams are used water activities like irrigation, industrial use.
- This water is also used for aquaculture (aqua farming ). Aquaculture is breeding , raising and harvest of aquatic animals like fish ( Matsya ), and aquatic plants .
- This water is also used for human consumption.
- The Dams have also been useful in supressing the floods .
Types of Dams
- Gravity Dam
- Arch Dam
- Arch – Gravity Dams
- Rock Fills Dams
- Earth-fill Dams
- Embankment Dams
- Concrete face rock fill Dams
Gravity Dam : A gravity dam is constructed from concrete or stone masonry . This designed in such a way that it can withstand load by its own weight its resistance against the foundation to oppose the horizontal pressure of water pushing against it.
These dams can be constructed to any height. The highest Gravity Dam in the world is Grande Dixence Dam, Switzerland.
Arch Dam : An Arch Dam have a curved upstream in plan. It is a curved shaped solid wall built with cement and concrete. On the basis of its radius , angle and curvature an arch dam is characterised into four types :-
- Constant Angle Arch Dam
- Double Curvature Arch Dam
- Variable Radius Arch Dam
- Constant Radius Arch Dam
An Arch Dam is made where the length is small in proportion to the height. The first Arch Dam in India is “Idukki Arch Dam”.
Rock Fills Dams : What is a rock filled dam? Rock-fill dams are a kind of dam that combines porous yet firmly packed gravel, sand, or silt in one section with an area of concrete, metal, clay, or some other substance that completely blocks water.
Embankment Dams : An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock.
It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core.
