Confined aquifer definition

Confined aquifer means an aquifer bounded above and below by impermeable beds or by beds of distinctly lower permeability than that of the aquifer itself; an aquifer containing confined ground water.
Confined aquifer means an aquifer bounded above and below by impermeable beds or by beds of distinctly lower permeability than that of the aquifer itself and containing ground water. An aquifer containing ground water, which is everywhere, at a pressure greater than atmospheric pressure and from which water in a well will rise to a level above the top of the aquifer.
Confined aquifer means an aquifer bounded above and below by beds of distinctly lower permeability than that of the aquifer itself, and which contains ground water under pressure greater than that of the atmosphere.

Examples of Confined aquifer in a sentence

  • Confined Aquifer - An aquifer that contains groundwater which is confined under pressure and bounded between significantly less permeable materials, such that waterwill rise in a fully penetrating well above the top of the aquifer.


More Definitions of Confined aquifer

Confined aquifer means an aquifer that is bounded above and below by impermeable beds or by beds that have a distinctly lower permeability than that of the aquifer itself. It is an aquifer that contains confined groundwater.
Confined aquifer means a saturated layer of permeable geologic material bounded above and below by confining layers, and in which water pressures are greater than atmospheric.
Confined aquifer means an aquifer in which ground water is confined under pressure that is significantly greater than atmospheric pressure.
Confined aquifer means an aquifer in which the groundwater is under pressure greater than atmospheric pressure. The static water level in a well tapping a confined aquifer rises to a level above the top of the aquifer.
Confined aquifer means an aquifer which contains ground water under pressure between or below relatively impermeable or significantly less permeable material so that the water surface rises above the top of the aquifer in a well which derives its water from that aquifer.
Confined aquifer means an aquifer which contains water under pressure overlain by impermeable formations such as clay or shale. In a well penetrating a confined aquifer, pressure will cause water to rise above the top of the aquifer. If the pressure in a confined aquifer is sufficiently great, water will rise above the ground surface and flow from a well, thus resulting in a “flowing artesian well” or a “naturally flowing well.”
Confined aquifer means the saturated sands and gravels of either the Dilwyn Formation or the Mepunga Formation in the Otway Basin, or the Renmark Group in the Murray Basin or any other aquifer located beneath these aquifers.
