Effects of climate change could have different impacts on groundwater storage: The expected more intense (but fewer) major rainfall events could lead to increased groundwater recharge in many environments. [18]: 104 But more intense drought periods could result in soil drying-out and compaction which would reduce infiltration to groundwater. [21]
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 ...
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.
Climate change is contributing to a global drying with no end in sight, according to a new study.
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.
For other aquifers, like the sand-based Upper Trinity Aquifer, it takes time for the rainfall to actually get down into it, so you would need much more consistent rain.
Saltwater intrusion is the movement of saline water into freshwater aquifers, which can lead to groundwater quality degradation, including drinking water sources, and other consequences. Saltwater intrusion can naturally occur in coastal aquifers, owing to the hydraulic connection between groundwater and seawater. Because saline water has a ...
California passed its landmark groundwater law in 2014. The goals of sustainable management remain a long way off.
