  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 process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface.

  3. Aquifer storage and recovery - Wikipedia

    en.wikipedia.org/wiki/Aquifer_storage_and_recovery

    The first agriculture ASR wells were put into service in Oregon in the autumn of 2006 and have injected well over 3,000 acre-feet (3,700,000 m 3) of water during the winter and spring flood flow times using artificial recharge (AR) of flood water as their water source. This shallow recharged water is then recovered as potable water and injected ...

  4. Groundwater banking - Wikipedia

    en.wikipedia.org/wiki/Groundwater_banking

    In-lieu recharge is the renewable surface water used to irrigate the farmland in place of using regular groundwater. [3] This is helping to save more groundwater because the water stays in the aquifer to be used later. [3] Direct recharge is storing water by allowing it to percolate directly to storage in the groundwater basin. [1]

    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. Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. [12]

    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.

    In several areas in Wisconsin the water level in aquifers is declining and recharge is not enough to replenish the aquifer. The state needs to control the addition of new wells that can be pumped ...

  9. Groundwater flow equation - Wikipedia

    en.wikipedia.org/wiki/Groundwater_flow_equation

    Or, for homogeneous aquifers, =. This formulation allows us to apply standard methods for solving linear PDEs in the case of unconfined flow. For heterogeneous aquifers with no recharge, Potential flow methods may be applied for mixed confined/unconfined cases.
