A molding, or other projection, in the wall of a building, to throw off the water, generally used in the United States for the first table above the surface of the ground see Table, n
The water table is the level below the surface of the ground where water can be found. Environmentalists say that diverting water from the river will lower the water table and dry out wells. the level below the ground where there is water. or groundwater table Surface of a body of underground water below which the soil or rocks are permanently saturated with water. The water table separates the groundwater zone (zone of saturation) that lies below it from the zone of aeration that lies above it. The water table fluctuates both with the seasons and from year to year because it is affected by climatic variations and by the amount of precipitation used by vegetation. It also is affected by withdrawing excessive amounts of water from wells or by recharging them artificially. See also aquifer
The upper surface of a zone of saturation, where the body of groundwater is not confined by an overlying impermeable formation Where an overlying confining formation exists, the aquifer in question has no water table
The upper surface of ground water or that level below which the soil is saturated with water It is at least 6 in thick and persists in the soil for more than a few weeks
the top surface of groundwater where all the spaces between soil particles and rocks are filled with water The boundary bewteen where the ground is saturated with water and where the ground is filled with water and air
The level below the earth's surface at which the ground becomes saturated with water The water table is set where hydrostatic pressure equals atmospheric pressure
the water surface in an unconfined aquifer; the level below which the pore spaces in the soil or rock are saturated with water; the upper surface of the zone of saturation
The natural accumulation of water either above or below ground, often used for well purposes May also refer to the distance from the surface of the land to the location of the water
A fluctuating demarcation line between the unsaturated (vadose) zone and the saturated (phreatic) zone that forms an aquifer It may rise or fall depending on precipitation (rainfall) trends The water table is semiparallel to the land surface above but is not always a consistent straight line Because of impervious beds of shale, etc , local water tables can be perched above the area's average water table
The level below the land surface at which the subsurface material is fully saturated with water The depth of the water table reflects the minimum level to which wells must be drilled for water extraction
