a subsurface area of the Earth in which all the pores or the material are filled with groundwater under pressure greater than atmospheric pressure.
Lower soil layers where all spaces are filled with water.
Groundwater zone within the Earth's bedrock where all available pores spaces are filled by water. Found beneath the water table.
The layer in the ground in which all available interstitial voids (cracks, crevices, holes) are filled with water.
The zone beneath the water table where all pore spaces are completely filled with water. Water that exists within this zone is known as "ground water".
