How are wetlands and aquifers related? How is Earth's groundwater and surface water replenished? How is an aquifer recharged? How does groundwater accumulate? How are aquifers, groundwater, and watersheds impacted by drought? How does water get into a groundwater aquifer?
How do wetlands recharge aquifers? Why does hyperopia happen in water? How does soil moisture evaporate? How can a confined aquifer become contaminated? How do pneumatic engine valves work? How does the bladder release urine? How does over-irrigation lead to salinization?
Unconfined aquifershave the water table, or the surface where water pressure equals atmospheric pressure, as their upper boundaries.Confined aquifers In the United States, the oldest groundwater, known asfossil water,is contained in the Ogallala Aquifer. Lying below about 175,000 square miles (450,...
Because the climate of the Great Plains is arid, water in the aquifer is being used faster than it can be recharged. That's why some scientists refer to using fossil water aquifers as water mining. Groundwater may also exist on other planets. Images from the Mars Global Surveyor spacecraft...
In fact, the vast majority of water on Earth is stored in aquifers, or underground rock formations, that hold 94.7% of the planet's water. Thus, deep groundwater and oceans account for 99.9% of the total. Glaciers and other forms of permanent and semipermanent ice take t...
Complementary, mathematical models are available to quantify MAR water injection rates required to recover groundwater depleted levels. Where should the injection be located? GALDIT is probably, today, the most used model worldwide to assess the vulnerability of saltwater intrusion in costal aquifers ...
In addition, the same process of liquid and gas interacting in pore spaces also applies to the way freshwater aquifers get recharged by rainfall, as the water percolates into the ground and displaces air in the soil. A better understanding of this process could be important for management of ...

The results from our studies indicate that modern waters recharged since 1954 have minimal affect on water quality in the main production aquifers. However, water storage and pressure in aquifers respond quickly to increase in pumping rate, potentially affecting land subsidence. Thus, we have to ...
