Artificial recharge

Artificial recharge (pronunciation: /ɑːrˈtɪfɪʃəl riːˈtʃɑːrdʒ/) is a process where water is put back into groundwater storage from surface-water supplies such as irrigation, or induced infiltration from streams or wells. The purpose of artificial recharge is to increase the amount of water in the ground, either for future use or to prevent water table decline and saltwater intrusion.

The term "artificial recharge" is derived from the combination of the words "artificial", meaning made or produced by human beings rather than occurring naturally, and "recharge", which in hydrology refers to the replenishment of groundwater storage.
