India also relies excessively on groundwater resources, which accounts for over 50 percent of the irrigated area with 20 million tube wells installed. India has built nearly 5,000 major or medium dams, barrages, etc. to store the river waters and enhance groundwater recharging. [15]
This page shows the state-wise list of dams and reservoirs in India. [1] [2] As of July, 2019, total number of large dams in India is 5,334. [3] About 447 large dams are under construction in India. [4] In terms of number of dams, India ranks third after China and the United States.
India's irrigation covered crop area was about 22.6 million hectares in 1951, and it increased to a potential of 90 mha at the end of 1995, inclusive of canals and groundwater wells. [31] However, the potential irrigation relies on reliable supply of electricity for water pumps and maintenance, and the net irrigated land has been considerably ...
This is an accepted version of this page This is the latest accepted revision, reviewed on 12 January 2025. Water located beneath the ground surface An illustration showing groundwater in aquifers (in blue) (1, 5 and 6) below the water table (4), and three different wells (7, 8 and 9) dug to reach it. Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in ...
However since the initial report, there has also been variations in groundwater levels. Bangalore, for example, experienced replenished ground water levels in 2021 due to COVID lockdown induced reduced demand and significantly increased rainfall. [25] However, this rise in ground water level is not considered to be a reversal of the downward trend.
Map of India based on survey of rivers of India.. The Indian rivers interlinking project is a proposed large-scale civil engineering project that aims to effectively manage water resources in India by linking rivers using a network of reservoirs and canals to enhance irrigation and groundwater recharge and reduce persistent floods in some parts and water shortages in other parts of the country.
Out of all the water on Earth, saline water in oceans, seas and saline groundwater make up about 97% of it. Only 2.5–2.75% is fresh water, including 1.75–2% frozen in glaciers, ice and snow, 0.5–0.75% as fresh groundwater and soil moisture, and less than 0.01% of it as surface water in lakes, swamps and rivers.
India accounts for 13 per cent of commitments in global water aid for 2006–07, receiving an annual average of about US$ 830 million (€620 million), more than double the amount provided to China. India's biggest water and sanitation donor is Japan, which provided US$ 635 million, followed by the World Bank with US$ 130 million.
