What Is A Water Surplus?
Water surplus is the extra water that is available for other uses. It depends on the water sources of the place. Water surplus is labelled as ‘Surplus’ because it is more than the amount of water used for irrigation. If the water surplus is more than the irrigation demand, then the excess water is used for other purposes. Water surplus is different from season to season or year to year. So water surplus is the extra water available during the season or year..
What happens water surplus?
Water surplus or surplus water is the extra water of a river or lake, compared with the average flow of water in the same place over a period of time. Water surplus is important to understand since it can have an impact on how pollution is measured. Water surplus is often calculated over a thirty-year period of average flows. For example, if a river or lake has a mean flow of 10m3 of water per second over a thirty-year period, an annual water surplus of 1 m3 per second means there are three extra months of water in that body of water. This extra water can be very useful to humans, for example, to make hydroelectricity or provide drinking water..
Where is there a water surplus?
While there is a water deficit in most of the states in India, few states have water surplus. The following states have surplus water:.
Why do water surpluses exist?
There are two reasons why water surpluses happen. First, the amount of water that evaporates from the surface of the Earth can exceed the amount of water that surfaces back. This is called evaporation. If there is more supply than demand for water, there will be water surpluses. The second reason is aquifer storage. Aquifers are natural underground reservoirs. The water in these aquifers can be extracted for human use. If the amount of water extracted from aquifers exceeds the amount of water that seeps into aquifers, there will be water surpluses. There are also two reasons why water shortages occur. First, the amount of water that seeps into aquifers can exceed the amount of water that is extracted. This is called infiltration. If there is less supply than demand for water, there will be water shortages. The second reason is surface storage. If the amount of water stored in surface reservoirs is exceeded by the amount of water extracted for human use, there will be water shortages..
What is surplus water regions?
Surplus water regions are those areas on Earth that can support additional population. Water is essential for human life – both for drinking and sanitation – and it is the primary resource priority for human settlement. Water availability varies by region of the country. High-risk populations (e.g., elderly) are more likely to experience acute health problems due to insufficient water..
