Artificial Groundwater Recharge
Artificial recharge is the practice of increasing by artificial means the amount of water that enters a groundwater reservoir (Todd, 1959). This includes, for example, direction of water to the land surface through canals, irrigation furrows or sprinkler systems, and injection of water into the subsurface through wells.
