Water Table
The level of ground water or the upper surface of the zone of saturation of groundwater above an impermeable layer of soil or rock (through which water cannot move) as in an unconfined aquifer.
water table (groundwater surface)
Free water surtace; groundwater elevation Elevation at which the pressure in the water is zero with respect to the atmospheric pressure. See also perched water table.

Water Table: The level of groundwater.
Water Treatment Lagoon: An impound for liquid wastes designed to accomplish some degree of biochemical treatment.
Water table: Level below the earth's surface at which the ground becomes saturated with water. The surface of an unconfined aquifer which fluctuates due to seasonal precipitation.
Water Table: The upper surface of the zone of saturation; the upper surface of the groundwater.
water table The level below which the soil or rock is saturated with water. Iit is also the upper boundary of the saturated zone. At this level, the hydraulic pressure is equal to atmospheric pressure.

In a shallow aquifer, a water table is the depth at which free water is first encountered in a monitoring well.
Watershed
The land area from which water drains to a given point.

Water Table: Upper surface of a zone of saturation, where that surface is not formed by a confining unit; water pressure in the porous medium is equal to atmospheric pressure (the phreatic surface).
Water Table: The upper surface of the groundwater; the level below which the soil is saturated with water. Its depth is influenced by rainfall and by human development (wells, drainage ditches, loss of wetlands, etc.).
The slope of the water table or aquifer. The hydraulic gradient influences the direction and rate of groundwater flow.

The zone above he water table within which the porous medium is saturated by water under less than atmospheric pressure.
Capture Efficiency
The fraction of organic vapors generated by a process that are directed to an abatement or recovery device.
The area below the water table where all open spaces are filled with water under pressure equal to or greater than that of the atmosphere.

The area below the water table where all open spaces are filled with water.
Saturation
The condition of a liquid when it has taken into solution the maximum possible quantity of a given substance.
1) The drop in the water table when water is being pumped from a well. It is the vertical distance between the static and the pumping levels of the wells. 2) The amount of water used from a tank or reservoir. 3) The drop in the water level of a tank ...
The porous material just above the water table which may hold water by capillarity (a property of surface tension that draws water upwards) in the smaller void spaces.

saturation, zone of place lying below the water table where the pore space is saturated with water under pressure greater than that of the atmosphere.
saturated zone The area below the water table where all open spaces are filled with water. Compare unsaturated zone.
paludification The expansion of a bog caused by the gradual rising of the water table as accumulation of peat impedes water drainage.
Lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is covered by shallow water.
Pet feces that is not tossed out is left on the ground, where it dissolves and flows untreated into the water table or San Francisco Bay.
Spodosols seem to form in situations that have a combination of periodically high and fluctuating water tables, coarse sediments, and vegetation having acid producing litter.
The zone between land surface and the water table within which the moisture content is less than saturation (except in the capillary fringe) and pressure is less than atmospheric. Soil pore space also typically contains air or other gases.

Cone of Depression: A depression in the water table that develops around a pumped well.
Cone of Influence: The depression, roughly conical in shape, produced in a water table by the pumping of water from a well.
WETLANDS: Areas with standing water or a high water table that under normal circumstances support vegetation typically adapted to saturated soil conditions; generally includes swamps, marshes, ...
Its extent is determined partly by the content of the soil water, but it cannot extend beyond the water table, below which voids are completely filled with water. [The Oxford Dictionary of Natural History. Allavy, M. Ed.; pg.662.
Aquifer: A porous, water-saturated layer of sediment and bedrock under the Earth's surface; also described as artesian (confined) or water table (unconfined).
bioswale: landscape element designed to capture rainwater runoff and remove silt and pollution before it enters the water table.
