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. Historical Large Well across Streamlet 9. Check Dams. Method # 1. Spreading Basins:

Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface.

2019年3月1日 · One method of controlling declining water levels is by using artificial groundwater recharge. The USGS monitors wells to evaluate the effect of groundwater depletion and recharge, and provides vital information to those who depend on groundwater resources.

Recharge or injection wells are subsurface groundwater recharge techniques used to directly discharge water into deep water-bearing zones. Recharge wells can be cased with the material covering the aquifer. If this material is unconsolidated, a screen can be placed in the well in the zone of injection.

A recharge well (injection well, inverted well, diffusion well, or disposal well) may be defined as a well that admits water from the surface to underground formations. Its flow is the reverse of a pumping well, but its construction should be the same.

Stated simply, artificial recharge is a process by which excess surface-water is directed into the ground – either by spreading on the surface, by using recharge wells, or by altering natural conditions to increase infiltration – to replenish an aquifer.

Recharge Wells: Deep, confined aquifers can be recharged by a recharge well. Its flow is the reverse of a pumping well but its construction may or may not be the same. If water is passed into a recharge well, a cone of recharge will be formed which is reverse of a cone of depression for a pumping well, Fig. 15.11.

Recharging directly into the saturated zone using injection wells is an attractive option where storage capacity has been enhanced by historical pumping, and the aquifer has sufficiently high transmissivity to accommodate target flow rates.

2020年6月22日 · Recharge wells are advantageous when land is scarce. Water can be injected into a well or borehole and recovered from another, some distance from the first, to increase travel time and benefit from the water treatment capacity of the aquifer. This is referred to Aquifer Storage Transfer and Recovery (ASTR).

Groundwater recharge is a vital process for maintaining sustainable groundwater resources, supporting ecosystems, and meeting human needs. This article explores the methods used for natural and artificial groundwater recharge, including infiltration basins, injection wells, recharge trenches, and spreading basins.
