Related terms include aquitard, which is a bed of low permeability along an aquifer, and aquiclude (or aquifuge), which is a solid, impermeable area underlying or overlying an aquifer, the pressure of which could lead to the formation of a confined aquifer.

The aquifer properties of the aquifer essentially depend upon the composition of the aquifer.The most important properties of the aquifer are porosity and specific yield which in turn give its capacity to release the water in the pores and its ability to transmit the flow with ease.
aquiclude A normally permeable rock, underlying or overlying an aquifer, which becomes impermeable because of the saturation of its pores by water, potentially creating a confined aquifer. [4] aquifer. Also aquafer.
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]
Contact springs, which occur along the side of a hill or mountain, are created when the groundwater is underlaid by an impermeable layer of rock or soil known as an aquiclude or aquifuge [4] Fracture, or joint occur when groundwater running along an impermeable layer of rock meets a crack (fracture) or joint in the rock.

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.
