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.
2.2 Water cycle intensification due to climate change. ... Groundwater tends to move slowly and is replenished slowly, so it can remain in aquifers for thousands of ...
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.
She said agencies can now use the approaches scientists have outlined to map strongholds of biodiversity and set targets for maintaining aquifer levels. “It’s very attainable,” she said.
This is because climate change leads to increased hydrological variability and extremes. Climate change has many impacts on the water cycle. These result in higher climatic and hydrological variability, which can threaten water security. [52]: vII Changes in the water cycle threaten existing and future water infrastructure.
