Climate change causes changes to the water cycle which in turn affect groundwater in several ways: There can be a decline in groundwater storage, and reduction in groundwater recharge and water quality deterioration due to extreme weather events.
This is an accepted version of this page This is the latest accepted revision, reviewed on 1 February 2025. Water located beneath the ground surface An illustration showing groundwater in aquifers (in blue) (1, 5 and 6) below the water table (4), and three different wells (7, 8 and 9) dug to reach it. Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in ...
When groundwater is extracted from an aquifer, a cone of depression is created around the well.As the drafting of water continues, the cone increases in radius. Extracting too much water (overdrafting) can lead to negative impacts such as a drop of the water table, land subsidence, and loss of surface water reaching the streams.
The sediment from the delta has built up to form a giant aquifer during flood season and retains water in the wetlands. The wetlands created and sustained due to built-up sediment are a habitat for numerous species of birds. [11] However, heavy sedimentation can reduce downstream river water quality and can exacerbate floods upstream.
To prevent more of these losses in an era when climate change is driving more severe droughts, Singer said, it’s crucial to “come up with creative solutions for the worst-case scenario.”
This shallow recharged water is then recovered as potable water and injected into the deep basalt aquifer. [citation needed] During the injection process, electrical energy can be generated by the head pressure of the water flowing back into the aquifer. This stored water is recovered during late summer and early autumn for irrigation needs.
Following the hottest summer globally on record, this year is all but certain to be the warmest in history, per Europe’s Copernicus Climate Change Service, with many extreme heat events felt ...
Aquifer compaction is a significant concern along with pumping-induced land subsidence. A large portion of the groundwater storage potential of many aquifers can be significantly reduced when longterm groundwater extraction, and the resulting groundwater level decline, causes permanent compaction of fine sediment layers (silts and clays).
