  2. Groundwater recharge - Wikipedia

    en.wikipedia.org/wiki/Groundwater_recharge

    Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer .

    This is an accepted version of this page This is the latest accepted revision, reviewed on 29 January 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 ...

  4. Aquifer - Wikipedia

    en.wikipedia.org/wiki/Aquifer

    Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface ...

  6. Spring (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Spring_(hydrology)

    Factors that affect the recharge include the size of the area in which groundwater is captured, the amount of precipitation, the size of capture points, and the size of the spring outlet. Water may leak into the underground system from many sources including permeable earth, sinkholes, and losing streams .

  7. Hydrogeology - Wikipedia

    en.wikipedia.org/wiki/Hydrogeology

    Groundwater engineering, another name for hydrogeology, is a branch of engineering which is concerned with groundwater movement and design of wells, pumps, and drains. [1] The main concerns in groundwater engineering include groundwater contamination , conservation of supplies, and water quality .

  8. Groundwater banking - Wikipedia

    en.wikipedia.org/wiki/Groundwater_banking

    Direct recharge is storing water by allowing it to percolate directly to storage in the groundwater basin. [1] With direct recharge it floods an area so that water seeps through the ground to get to the aquifers. [3] The water is then pumped out when there is more of a demand with the use of recovery wells. [3]

  9. Water resources - Wikipedia

    en.wikipedia.org/wiki/Water_resources

    Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. These resources can be either freshwater from natural sources, or water produced artificially from other sources, such as from reclaimed water or desalinated water (). 97% of the water on Earth is salt water and only three percent is fresh ...
