Water resources play a vital role in daily life in India and are used for agriculture, industry, households, recreation, and the environment. The main types of water resources available in India are oceans, surface water sources like rivers and lakes, and groundwater accessed via wells and bore-wells. Groundwater is the most abundant freshwater resource, and there is significant interaction between surface and groundwater with groundwater feeding surface water sources. Surface water meets much of the country's needs for public water supply, irrigation, industry, and hydroelectric power.

3.  Water resources are defined as the
sources by which we can get the
water for our different types of
uses.
 Water resources play a vital role in
our day to day life.

4. Uses of water include:
Agricultural,
Industrial,
Household,
Recreational and
Environmental activities.
Virtually all of these human uses require
fresh water.

supplies.
Desalination plants help to make fresh water but they are
few because the energy required for desalination makes the
process extremely expensive.
We benefit from saltwater resources.
Saltwater fish are a staple in much of the India's coastal
diet.
Tidal waters are being used as a source of hydroelectric
energy.

resources.
As water soaks into the ground, some of it adheres to
clay and soil to provide water to the plants.
Gravity moves the water down through the ground.
Eventually, the water reaches the saturated zone,
where all the pores are filled with water.
The separation between the saturated and
unsaturated zone is called the water table.
There is significant interaction between surface
water and ground water. Groundwater feeds surface
water through springs.

11.  Surface water can also recharge groundwater supply.
 Groundwater is accessed by wells & bore-wells.
 Surface water is the water that exists in streams, rivers
and lakes.
 This water is used for potable water supply, recreation,
irrigation, industry , livestock, transportation and
hydroelectric energy.
 Over 63 percent of the public water supply is
withdrawn from surface water. Irrigation gets 58% of
its water supply from surface water. Industry gets
almost 98 percent of its water from surface water
systems. Therefore, surface water conservation and
quality is of utmost importance.
