National water Grid concept

The vast amount of water flows every year in thousands of rivers of India but the distribution of water flows is not uniform in terms of time and place. Eg perennial. Water flows throughout the year in the rivers, whereas in seasonal rivers the amount of water decreases during the dry season. Most of the water of the rivers is wasted during the rainy season. Similarly, when floods are causing havoc in one part of the country, at the same time another part of the country is struggling with the problem of drought. National Water Grid
Concept) Geographical heterogeneity is found in distribution of water sources in India. This inequality of water distribution can be reduced by transferring the water from water sufficient river basin to a water-deficient river basin. A plan has been made to connect river basins in India, called the National Water Grid. The main objective of this concept is to make proper planning of the precious water transported by the rivers to the sea. Under this, the areas with water surplus and water deficit will be connected geographically by link canals. A balance will be established by this exchange of water resources. For example, through the Ganga-Kaveri link, additional water of the Ganga river will be transported to the Kaveri Basin. Similarly, Chambal Rajasthan link will carry the Chambal river water to the drought-hit areas of Rajasthan. Many small and big rivers and connecting them will form a network called National Water Grid. The Supreme Court has also given a historic direction to the central government to connect the major rivers of the country by 2012.

Highlights of National Water Grid Concept (i) Water Supply Committee for Irrigation in drought prone areas
(ii) Accumulation of excess rainwater in artificial reservoirs created in different parts of the country.
(iii) Irrigation of additional 350 lakh hectares of arid and semi-arid area by links and canals
(iv)Generating about 400 lakh kWh of additional power from reservoirs built for linkage of plateau and dams

Future Framework-
(1) In this phase of globalization and development, development of national water grid has become an indispensable necessity. The need for more seedling production is needed for the supply of a growing population, which requires water for irrigation in the country especially in areas with Virgin lands till drought.
(ii) Broadly, the triangular area of ​​Ahmedabad-Kanpur-Jalandhar and the eastern rain shadow regions of the Western Ghats fall in drought-prone areas. These areas will be particularly benefited by the creation of a national grid.
(iii) With the construction of this grid, about 77 percent of the total water discharged by the rivers of the country will be used. Directions of Interlink Link - Under this scheme there will be two directions of Interlink Link - North to South, East to West.
The schemes which have been completed - 1. Periyar Visakhan(Diversion) Schem,
2. Kurnool-Kadapa Canal,
3. Parambikulam Aliyar Project.
Schemes under construction -
1. Indira Gandhi Canal,
2. Beas-Sutlej link
3. Ramakanga to Visakhan in the Ganges.

Proposed Schemes -
1. Ganga-Kaveri link,
2. Ganga-Brahmaputra link,
3. Narmada to Gujarat and canal of western Rajasthan,
4. Chambal-Rajasthan link,
5. Link of the rivers of the Western Ghats to the east located rain shadow region.

Problems related to river water use -
In addition to the huge challenges of capital, engineering and construction in front of a nationally rugged country like India,
River water use has to find solutions to the following problems
(i) River water disputes between states (ii) ) Uneven flow of seasonal water
(iii) Inadequate quantity of water
(iv) Silt in river water
(v) Shrinkage of river channels due to expansion of settlements towards mid stream
(vi) River water pollution
