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. Recharge occurs both naturally (through the water cycle) and through anthropogenic processes (i.e., "artificial groundwater recharge"), where rainwater and or reclaimed water is routed to the subsurface.

  • 涵養(かんよう、地下水涵養)とは、地表の水(降水や河川水)が地下に浸透し、地下水となることを指す。 河川や湖沼といった表流水に水が加わることは「涵養」とは呼ばない。常用漢字にないため、公的にはしばしば「かん養」と表記される(「水源かん養保安林」など)。 比喩的な意味では、水が自然に土に浸透するように、無理をしないでゆっくりと養い育てることを意味する。「読書力を―する」
  • La réalimentation des aquifères ou infiltration résulte naturellement d'un processus hydrologique par lequel les eaux de surface percole à travers le sol et s'accumulent sur le premier horizon imperméable rencontré (banc d'argile ou de marne) ; elle peut aussi être assurée artificiellement par des puits filtrants. Ce processus s'amorce généralement à partir de la zone vadose, sous la pédosphère où les racines des végétaux captent encore l'essentiel de l'eau interstitielle. La réalimentation est caractérisée par le débit de filtration alimentant le toit de l'aquifère.

  • Глуби́нный дрена́ж — метод понижения грунтовых вод и отведения воды за пределы участка (сооружения) с помощью системы дренажных труб (дрен), уложенных по всему периметру осушаемого участка.
