Related concepts include aquitard, a bed of low permeability along an aquifer, and aquiclude (or aquifuge), a solid and impermeable region underlying or overlying an aquifer, the pressure of which could lead to the formation of a confined aquifer. Aquifers can be classified as saturated versus unsaturated; aquifers versus aquitards; confined ...

The water table may vary due to seasonal changes such as precipitation and evapotranspiration.In undeveloped regions with permeable soils that receive sufficient amounts of precipitation, the water table typically slopes toward rivers that act to drain the groundwater away and release the pressure in the aquifer.
Geological strata giving rise to an artesian well Schematic of an artesian well U.S. Navy Seabees tapping an artesian well in Helmand Province, Afghanistan. An artesian well is a well that brings groundwater to the surface without pumping because it is under pressure within a body of rock or sediment known as an aquifer. [1]

The terms aquitard, aquiclude, aquifuge are used without any proper definition, implying even that aquiclude and aquifuge are synonyms. — Preceding unsigned comment added by 128.178.7.131 ( talk ) 16:03, 28 November 2012 (UTC) [ reply ]
