What Is Groundwater Recharge?

Groundwater recharge (recharge to groundwater) refers to the replenishment of groundwater volume through a variety of means such as rainfall, irrigation, underground runoff, canals or river leakage.

Chinese name: Groundwater recharge
Foreign name: recharge to groundwater

Main source: Atmospheric precipitation and surface water infiltration
the way: Atmospheric precipitation, surface water, condensed water, artificial

Groundwater recharge definition

Groundwater recharge is the entire process by which aquifers or systems receive water from the outside. ^[1]

Groundwater recharge research

The research content includes the source of groundwater recharge, the conditions of recharge, the amount of recharge and the factors affecting recharge. Recharge sources include atmospheric precipitation, surface water, condensed water, irrigation return water, overflow of aquifers and specialized artificial recharge recharge. Many researches have been done on various recharge effects, especially precipitation infiltration and river water recharge. Many researchers at home and abroad have applied isotope technology to hydrology and hydrogeology, which is of great scientific significance for studying groundwater recharge, source, formation, and conversion mechanism of surface water and groundwater. ^[1]
