Surface water is naturally replenished by precipitation and naturally lost through discharge to the oceansevaporationevapotranspiration and groundwater recharge. Although the only natural input to any surface water system is precipitation within its watershedthe 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 reservoirsthe 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 loss.
By Various Contributors The meaning of water management Water management means dealing with water in the best possible way.
This can be done by local authorities municipal water management or it can be done by individuals at home when we manage how we use our own water supplies.
Good water management will involve organizing water so that everyone has enough, and controlling water supplies and water treatment centers and other equipment and logistics relating to water so that they work in the best possible way.
It thus often involves some knowledge of the chemical properties of water. The importance of water management Water management affects many aspects of our lives. Water is so common that we often do not think about where it comes from or where it is managed.
But, bad water management can really hit us hard. Below are some key ways in which water management is important. So clean drinking water is a necessity for us. Without water, we can only survive for a few days at most. But, if we have water and no food, we can survive for several weeks.
This shows just how crucial it is that we have daily access to clean water that is suitable for drinking. If we have pets, they will need daily access to water too.
A clean water supply is important for this too. From washing our hands before a meal to deep cleaning a hospital floor, we need clean water for almost all aspects of good hygiene.
A good water supply is needed to prevent hunger and famine. Swimming pools and other facilities need to be well maintained so that they remain safe and enjoyable places to be. Swimming pool water needs to be managed by treating it with chlorine and regularly testing its levels of bacteria and other substances, for instance, to ensure that it is safe for people to swim in.
Methods of water management There are several water management methods available in the world, and these are being honed all the time as scientists and engineers find new ways to look after our water supplies.
Below are 5 key water management strategies that are widely used today. Waste water systems — recycling and treating: These systems are absolutely essential for ensuring that our waste water does not cause us to fall ill.
These systems can be managed so that water is not wasted — and they can use recycled water or rain water to avoid unnecessarily depleting water supplies. Water can also be conserved by generally consuming less. Not many people realize how much water goes in to the production of a car or an item of clothing, for example.
Cutting down on the amount of things that we buy can really reduce the amount of water that is needed to support our lifestyle.
Caring for the natural water supplies: Both fresh water ecosystems and marine ecosystems are home to a wide variety of different organisms and without the support of these ecosystems, these organisms would most likely become extinct. Good water management thus also involves ensuring that we do not pollute natural water sources.
Effective implementation of plans — ensuring that everyone has enough water: However, in many parts of the world, people have to walk many miles in order to access clean water.
So, good water management systems are only truly praiseworthy if they are implemented throughout the world so that everyone can benefit from them.The importance of water Water is one of the most important substances on earth. All plants and animals must have water to survive.

Failing to evacuate flooded areas, entering flood waters, or remaining after a flood has passed can result in injury or death. Flooding is a temporary overflow of water onto land that is normally dry. Floods are the most common natural disaster in the United States.
Floods may:Result from rain, snow, coastal storms, storm surges, and overflows of dams and other water. Page 5 II. WATER CHEMISTRY CONTROL Based on many hundreds of surveys, we find that operational control of cooling water treatment programs is often neglected and that it is the single most common cause of water management.
Water resources are natural resources of water that are potentially useful. Uses of water include agricultural, industrial, household, recreational and environmental activities. All living things require water to grow and reproduce. 97% of the water on the Earth is salt water and only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps.
Division of Environmental and Financial Assistance Office of Financial Assistance Promoting water quality benefits by financing cost-effective and environmentally sound wastewater and drinking water infrastructure improvements and other water resource projects.
Water resource management is a very important issue from several angles such as development of water bodies for future, protection of available water bodies from pollution and over exploitation.
