Hydrologic sciences - Groundwater, Aquifers, Recharge: Some rocks allow little or no water to flow through; these are known as impermeable rocks, or aquicludes. Others are permeable and allow considerable storage of water and act as major sources of water supply; these are known as aquifers. Aquifers overlain by an impermeable layer are called confined aquifers; aquifers overlain by an ... An unconfined aquifer can also occur as a perched aquifer. Most commonly, perched aquifers form and are maintained by recharge that accumulates on aquitards in the vadose zone. Perched groundwater forms above a layer of lower permeability material within the vadose zone where the migration of percolating recharge is slowed to the extent that it ...

Aquifers. An aquifer consists of layers or units of sands, gravels and rocks that contain sufficient saturated and permeable geologic material to yield a useable, sustainable amount of potable groundwater. The supply of underground water originates from surface water infiltrating into the ground and accumulating in the geological deposits. Unconfined aquifers are those that are bounded by the water table. Some aquifers, however, lie beneath layers of impermeable materials. These are called confined aquifers, or sometimes artesian aquifers. A well in such an aquifer is called an artesian well. The water in these wells rises higher than the top of the aquifer because of confining ...
