3. Introduction:
This is virtual booklet of water
resources is going to be about how
people use water, how we would
have to take care of it and many
things that with this booklet you
should learn. Also with this booklet
you should learn how to not waste
the water and enjoy you to practice
it to save this beautiful world.

4. Prior knowledge:
Are sources of water and they
are useful from the humans and
animals.
Water resources is important on
Earth and without it we can’t do
many things or satisfied our
needs.
We would have to take care of
the water because in few years
there's not going to be enough
water for us.
Water is a renewable natural
resources also like air and soil.

5. About Water resources:


Fresh water is renewable resources like soil and air.
The worlds is supplied by clean and fresh water and
itis decreasing. Water is one of our most critical
resources, but around the world it is under threat.
Water demand already exceeds supply in many parts
of the world and as the world population continues
to rise, so too does the water demand.

6. 
Are sources of
water that are
useful to
humans. Uses of
water include
agricultural,
industrial,
household,
recreational and
environmental
activities.
Virtually all of
these human uses
require fresh
water.

7. Division of Water resources:
Water resources are divisible into two distinct
categories : the surface-water resources and
the ground-water resources. Each of these
categories is a part of the earth's water
circulatory system, called the hydrologic cycle,
and is derived from precipitation, which is
rainfall plus snow.

8. Distribution of water:

9. Source of fresh water:

10. Ground Water:
Sub-surface water, or groundwater, is fresh
water located in the pore space of soil and
rocks. It is also water that is flowing within
aquifers below the water table.
Desalination:
Desalination is an artificial process by
which saline water (generally sea water) is
converted to fresh water.

11. Frozen Water:
Several schemes have been proposed to
make use of icebergs as a water source,
however to date this has only been done for
novelty purposes. Glacier runoff is
considered to be surface water.

12. Uses of water:
 Agricultural: It is
estimated that 69% of
worldwide water use is for
irrigation, with 15-35% of
irrigation withdrawals being
unsustainable. Aquaculture is
a small but growing agricultural
use of water.
Industrial: It is estimated
that 15% of worldwide water
use is industrial. The
distribution of industrial water
usage that is varies widely, but
as a whole is lower than
agricultural use.
