Unsaturated zone definition
Unsaturated zone or "zone of aeration" means the zone between the land surface and the water table.
Unsaturated zone means the zone between the land surface and the water table.
Unsaturated zone or "vadose zone" means the subsurface zone containing water under pressure less than that of the atmosphere, including water held by capillary forces within the soil, and containing air or gases generally under atmospheric pressure. This zone is limited by the ground surface and the upper surfaces of the water table.
Examples of Unsaturated zone in a sentence
Unsaturated zone soils that appear to contain chemicals above TCLs are excavated, screened, stockpiled, and managed as described in the previous sections.
More Definitions of Unsaturated zone
Unsaturated zone means the volume between the land surface and the uppermost saturated zone.
Unsaturated zone means the subsurface zone con- taining water under pressure less than that of the atmosphere, including water held by capillary forces within the soil and con- taining air or gases generally under atmospheric pressure. This zone is limited above by the ground surface and below by the upper surface of the zone of saturation or the water table.
Unsaturated zone means the zone between the land surface and the nearest saturated zone, in which the interstices are occupied partially by air.
Unsaturated zone means that part of the subsurface where interconnected voids are not all filled with water.
Unsaturated zone means the subsurface zone containing water under a hydrostatic pressure less than atmospheric, including water held by capillary forces within the soil containing air or gases generally under atmospheric pressure. This zone is limited above by the ground surface and below by the upper surface of the zone of saturation.
Unsaturated zone means the zone between the land surface and the water table in which the pore spaces contain water at less than atmospheric pressure, as well as air and other gases.
Unsaturated zone means the zone between the land surface and the regional water table. Generally, fluid pressure in this zone is less than atmospheric pressure, and some of the voids may contain air or other gases at atmospheric pressure. Beneath flooded areas or in perched water bodies the fluid pressure locally may be greater than atmospheric.
