Groundwater zone within the Earth's bedrock where all available pores spaces are filled by water. Found beneath the water table.

In hydrologic terms, the locus of points below the water table where soil pores are filled with water. This is also called the phreatic zone

The zone below the zone of aeration in which all pore spaces are filled with water.

area below a water table, where groundwater saturates the rocks and soil.

(Also called phreatic zone.) That portion of the lithosphere in which the pore spaces are filled with water, that is, the region beneath the water table.

The zone in which all the connected interstices or voids in permeable rock or soil formation are filled with water under pressure equal to or greater than atmospheric pressure.

The space in the soil below the water table in which all the pores are filled with water. The water in the zone of saturation is groundwater.

Lower levels of soil where all spaces are filled with water.

the portion of the ground below the water table where all the pores in rock, sediment, and soil are filled with water

The soil or rock located below the top of the groundwater table. By definition, the zone of saturation is saturated with water. Also see water table.
