The zone of aeration. Animation by: Bramer. Groundwater is all the water that has penetrated the earth's surface and is found in one of two soil layers. The one nearest the surface is the "zone of aeration", where gaps between soil are filled with both air and water. Below this layer is the "zone of saturation", where the gaps are filled with water.

Zone of Aeration. A zone below the land surface but above the water table, where pore spaces are filled mainly with air. Water that exists in the pore space in this zone is referred to as "soil moisture." The "capillary fringe," where capillary action draws moisture from the water table upwards, is considered to be part of the zone of aeration.

The zone of aeration. They are vadose water present in the zone of aeration and groundwater present in the zone of saturation. The vadose water is further subdivided into three zones, i.e., soil water zone, intermediate zone and capillary zone. Fig. 1.2 shows the classification of groundwater. The soil water zone is adjacent to the ground surface.
