The upper surface of the Zone of saturation of soil by ground water.
n. The level below which the ground is saturated. Any hole in the ground will fill with water when the water-table has been reached. This level often fluctuates with rainfall. The water-table is thus the upper surface of the groundwater.
a surface of an unconfined body of ground water at which the pressure is equal to the atmospheric pressure.
The upper limit in the soil or underlying material permanently saturated with water.
The surface of a groundwater body at which the water pressure is atmospheric. Unless the water-table is coincident with the ground surface, an unsaturated zone will be present.
