Water management is the practices of planning,
developing, distribution and optimum utilizing
of water resources under defined water polices
and regulations.
It may mean:
management of water treatment of drinking water,
industrial water, sewage or wastewater
management of water resources
management of flood protection
management of Irrigation.

WATER
RESOURCES
Water resources are sources of water that are
useful or potentially useful to humans. Uses
of water include:
agricultural,
industrial,
household,
recreational,
environmental activities.
Virtually all of these human uses require fresh
water. 97.5% of water on the Earth is salt water,
leaving only 2.5% as fresh water of which over
two thirds is frozen in glaciers and polar ice
caps.
The remaining unfrozen freshwater is mainly found
as groundwater, with only a small fraction present
above ground or in the air.
Fresh water is a renewable resource, yet the world's
supply of clean, fresh water is steadily decreasing.
Water demand already exceeds supply in many parts of
the world, and as world population continues to rise
at an unprecedented rate, many more areas are expected
to experience this imbalance in the near future.
The framework for allocating water resources to water
users (where such a framework exists) is known as
water rights.

SURFACE
WATER
Surface water is water in a river,
lake or fresh water wetland.
Surface water is naturally replenished by
precipitation and naturally lost through
discharge to the oceans, evaporation, and
sub-surface seepage.
Although the only natural input to any surface
water system is precipitation within its watershed,
the total quantity of water in that system at any
given time is also dependent on many other factors.
These factors include storage capacity in lakes,
wetlands and artificial reservoirs, the permeability
of the soil beneath these storage bodies, the runoff
characteristics of the land in the watershed, the
timing of the precipitation and local evaporation rates.
All of these factors also affect the proportions of
water lost.

SUB-SURFACE
WATER
Sub-Surface water travel time 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.
Sometimes it is useful to make a distinction
between sub-surface water that is closely
associated with surface water and deep
sub-surface water in an aquifer,
(sometimes called "fossil water").

AMERICAN
GROUND
WATER
TRUST
The American Ground Water Trust is a national
not-for-profit organization. The educational
mission of the Trust is to:
Promote groundwater protection and resource
sustainability,
Communicate the environmental and economic
value of groundwater,
Showcase groundwater science and technology
solutions,
Increase citizen, community and decision-maker
awareness,
Facilitate stakeholder participation in water
resources decisions.

SECTION 6
WATER
STORAGE
Water is stored in reservoirs
(large impoundments) for:
flood control,
water supply,
hydropower production,
recreation.
Reservoir storage affects water quality
because a hydrologic system developed
under flowing-water conditions (i.e.,
a stream or river) has been changed to
a water storage area.
