Write about five different uses of freshwater

The availability and quality of water always have played an important part in determining not only where people can live, but also their quality of life. Even though there always has been plenty of fresh water on Earth, water has not always been available when and where it is needed, nor is it always of suitable quality for all uses. Water must be considered as a finite resource that has limits and boundaries to its availability and suitability for use.

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. Human activities can have a large and sometimes devastating impact on these factors. Humans often increase storage capacity by constructing reservoirs and decrease it by draining wetlands. Humans often increase runoff quantities and velocities by paving areas and channelizing the stream flow.

The total quantity of water available at any given time is an important consideration. Some human water users have an intermittent need for water. For example, many farms require large quantities of water in the spring, and no water at all in the winter.

To supply such a farm with water, a surface water system may require a large storage capacity to collect water throughout the year and release it in a short period of time.

Other users have a continuous need for water, such as a power plant that requires water for cooling.

To supply such a power plant with water, a surface water system only needs enough storage capacity to fill in when average stream flow is below the power plant's need.

Nevertheless, over the long term the average rate of precipitation within a watershed is the upper bound for average consumption of natural surface water from that watershed.

Natural surface water can be augmented by importing surface water from another watershed through a canal or pipeline. It can also be artificially augmented from any of the other sources listed here, however in practice the quantities are negligible.

Humans can also cause surface water to be "lost" i.

The freshwater biome

Brazil is estimated to have the largest supply of fresh water in the world, followed by Russia and Canada. For many rivers in large valleys, this unseen component of flow may greatly exceed the visible flow. The hyporheic zone often forms a dynamic interface between surface water and groundwater from aquifers, exchanging flow between rivers and aquifers that may be fully charged or depleted.

This is especially significant in karst areas where pot-holes and underground rivers are common. Groundwater Relative groundwater travel times in the subsurface Groundwater is fresh water located in the subsurface 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 groundwater that is closely associated with surface water and deep groundwater in an aquifer sometimes called " fossil water ". A shipot is a common water source in Central Ukrainian villages Groundwater can be thought of in the same terms as surface water: The critical difference is that due to its slow rate of turnover, groundwater storage is generally much larger in volume compared to inputs than it is for surface water.

This difference makes it easy for humans to use groundwater unsustainably for a long time without severe consequences. Nevertheless, over the long term the average rate of seepage above a groundwater source is the upper bound for average consumption of water from that source.

The natural input to groundwater is seepage from surface water. The natural outputs from groundwater are springs and seepage to the oceans. If the surface water source is also subject to substantial evaporation, a groundwater source may become saline.

This situation can occur naturally under endorheic bodies of water, or artificially under irrigated farmland. In coastal areas, human use of a groundwater source may cause the direction of seepage to ocean to reverse which can also cause soil salinization. Humans can also cause groundwater to be "lost" i.

Humans can increase the input to a groundwater source by building reservoirs or detention ponds.Of all the water on the earth, humans can used only about three tenths of a percent of this water. Such usable water is found in groundwater aquifers, rivers, and freshwater lakes.

The United States uses about , million gallons of fresh water every day. Even though discussions of water use typically focus on fresh-water use, saline water use also is important in the United States. Some categories of water use, such as thermoelectric, industrial, and mining, use saline water, mainly for cooling generators in thermoelectric power plants.

The uses of water include drinking, washing and cleaning, cooking, transportation, providing hydroelectric power, irrigation and recreation.

Living beings need water to move nutrients into their cells and to help them excrete wastes and toxins.

Although saline water is used for some purposes, mainly to produce electricity, when people think of the water they use every day, they mostly are considering freshwater.

Uses of fresh water 1. WATER AS A RESOURCE Water resources are sources of water that are useful or potentially useful. The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air.

This is a considerable amount, when compared to that required for drinking, which is. write five uses of fresh water. Go. What are the five different uses of fresh water in Pakistan? The International Boundary between Canada and the US runs through several dozen freshwater.
