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.
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 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 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.”
