What is a groundwater recharge basin?
These are natural or artificially constructed places that collect surface water, most often in the form of rain or snowmelt. The water in these basins eventually drains down through the soil and replenishes the groundwater level in the aquifer. But recharge basins can do more than just increase groundwater levels.

Which are the method of recharging?
Direct recharge methods can be grouped into three categories: (i) when the aquifer is shallow, water may be spread over fields or conveyed to basins and ditches from which it percolates; (ii) when an aquifer is situated at greater depths, recharge can be facilitated by flooding pits and dug shafts; and (iii) in cases …
What is a groundwater basin?
Groundwater basin – an alluvial aquifer or a stacked series of alluvial aquifers with reasonably well- defined boundaries in a lateral direction and having a definable bottom. Groundwater mining – the process, deliberate or inadvertent, of extracting groundwater from a source.
Which is the best method for groundwater recharge?
For example, groundwater can be artificially recharged by redirecting water across the land surface through canals, infiltration basins, or ponds; adding irrigation furrows or sprinkler systems; or simply injecting water directly into the subsurface through injection wells.
What are the examples of groundwater?
The water that your well draws from under the ground is an example of groundwater. Water that exists beneath the earth’s surface in underground streams and aquifers. Water beneath the earth’s surface, often between saturated soil and rock, that supplies wells and springs.
Why is groundwater bad?
Groundwater is vulnerable to contamination from a range of activities, such as industrial and agricultural enterprises and changes in land-use. Poor management of groundwater can cause many significant water quality problems, such as rendering water unfit for human or animal consumption.
What are the solution of groundwater?
One of the most effective ways to address the issue of groundwater depletion is to find alternative sources of water. Alternative water sources can be used to help replenish aquifers. Deriving water from other sources would also give aquifers time to refill instead of pumping too much water from them at once.
How do you recharge groundwater?
This article throws light upon the top nine methods of groundwater recharge. The methods are: 1. Spreading Basins 2. Recharge Pits and Shafts 3. Ditches 4. Recharge Wells 5. Harvesting in Cistern from Hill Sides 6. Subsurface Dams 7. Farm Ponds 8.
How do Wetlands recharge groundwater?
Groundwater recharge and discharge: Some wetlands recharge groundwater by holding surface water and allowing it to slowly filter into the groundwater reserves. Some wetlands are discharge areas; they receive groundwater even during dry periods, and help maintain flows in nearby rivers and streams.
What is a significant groundwater recharge area?
Significant Groundwater Recharge Areas (SGRAs) are surfaces on the landscape that allow a high volume of water to penetrate the surface – higher than the average for the entire watershed. The soil in these areas is typically characterized by permeable, loosely packed, coarse materials such as gravels and sand or fractured bedrock at surface which allow rain and snowmelt to enter the ground easily.
Why are artificial recharge of groundwater?
The basic purpose of artificial recharge of ground water is to restore supplies from aquifers depleted due to excessive ground water extraction/ exploitation/ use. Artificial recharge (also known as aquifer re-injection) is the process of injecting (or recharging) water into the ground in a controlled way, by means of special recharge wells.
