Groundwater Recharge - Process where water enters the soil and eventually reaches the saturated zone.
The addition of water to the saturated zone is called groundwater recharge. In another context, recharge may refer to the amount of water added per unit of time, e.g. cubic metres per year. The recharge area is simply the geographic area in which recharge occurs.
inflow of water to a groundwater reservoir from the surface. Infiltration of precipitation and its movement to the water table is one form of natural recharge. Also, the volume of water added by this process.
