Groundwater discharge is the movement of water out of an area of saturated soil. Rainwater seeps into the ground and moves downwards through the soil until a saturated zone is reached, called an aquifer. Here, openings and gaps in the soil and rock are filled with water, called groundwater. The top of this saturated zone is called the water table. Water moves into aquifers in locations called groundwater recharge areas, and moves out of aquifers as groundwater discharge in locations called discharge points.
