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 ...
Use of groundwater, especially for irrigation, may also lower the water tables. Groundwater recharge is an important process for sustainable groundwater management, since the volume-rate abstracted from an aquifer in the long term should be less than or equal to the volume-rate that is recharged.
Graphic on Groundwater Flow. Groundwater-Dependent Ecosystems (or GDEs) are ecosystems that rely upon groundwater for their continued existence. Groundwater is water that has seeped down beneath Earth's surface and has come to reside within the pore spaces in soil and fractures in rock, this process can create water tables and aquifers, which are large storehouses for groundwater.
New research shows that persistent groundwater extraction over more than a decade has shifted the axis on which our planet rotates. Humans pump so much groundwater that Earth’s axis has shifted ...
Groundwater pumping has been causing the land to sink at a record pace in California's San Joaquin Valley. New research suggests ways of addressing the problem. Groundwater pumping is causing land ...
And so it was able to outcompete the native vegetation.” She said efforts to prevent this sort of habitat degradation should be prioritized. Read more: Groundwater depletion is worsening worldwide.
The hyporheic zone is the region of sediment and porous space beneath and alongside a stream bed, where there is mixing of shallow groundwater and surface water.The flow dynamics and behavior in this zone (termed hyporheic flow or underflow) is recognized to be important for surface water/groundwater interactions, as well as fish spawning, among other processes.

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.
