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.

The problem is driven by groundwater overdraft, which occurs when the amount of water pumped out exceeds the amount of recharge. When clay layers in aquifers are drained and collapse, the loss of ...
Groundwater recharge is the process of allowing excess surface water to swap into underground aquifers. Groundwater recharge is vital to mitigating subsidence and minimizes the consequential damage. The amount of recharge that occurs in the San Joaquin Valley is very dependent on the amount of rain received in winter and spring months and ...
California’s San Joaquin Valley may be sinking nearly an inch per year due to the over-pumping of groundwater supplies, with resource extraction outpacing natural recharge, a new study has found.
The groundwater supply across the country is depleting at an alarming rate. A new study found that groundwater supplies around the world are depleting faster than they were 40 years ago.
The coastal groundwater system consists of terrestrial groundwater, seawater and a mixture of two. Rainfall is the main source of the recharge of terrestrial groundwater. In the mixing zone, dilution occurs that results in the different chemical compositions of water there.
One way is through a “managed aquifer recharge,” which floods an area with water using a different source like surface water and lets it infiltrate down into the aquifer.
