Aquiclude vs aquitard

Aquitard; Aquiclude; Aquifuge; 1. Aquifer. An aquifer is a saturated formation of the earth. It not only stores the water but also yields it in adequate quantity. Aquifers are highly permeable formations and hence they are considered as main sources of groundwater applications. Unconsolidated deposits of sand and gravel are examples of an aquifer..

AGU, 16(2), 519 – 524 ...A confined aquifer is somewhat shielded, the water tends to contain fewer contaminants, and the water levels are not as responsive to short‑term variations in precipitation. The water in a confined aquifer often has a longer residence time in the groundwater system as shown in Figure 28b. While unconfined water can have a very long residence ...Several important biogeochemical reactions are known to occur near the interface between aquifer and aquitard sediments. These reactions include O2 reduction; denitrification; and Fe3+, SO42-, and CO2 (methanogenesis) reduction. In some settings, these reactions occur on the aquitard side of the interface as electron acceptors move …

12-14. An unconfined aquifer is situated above a horizontal impervious base and is composed of sand with a hydraulic conductivity of 12m/day. In this aquifer, two fully penetrating ditches from a strip of land with a constant width of 1200m. The water level in the left and right ditches rises to 8 and 12m above the impervious base, respectively.

In the simplest sense, you might imagine an aquifer formation that may be covered by a veneer of soil, and which extends downward from a few feet below the surface for several tens or even hundreds of feet (Figure 3). At some depth below the land surface, the interstices between soil or sediment particles, or the fractures in ...Aquifer types: The High Plains, like most Kansas aquifers, is an unconsolidated, unconfined aquifer. Other terms similar to 'unconfined' are 'water table,' or 'phreatic,' aquifer.

For example, sand lenses in a clay formation will form an aquitard. Also known as a leaky confining layer. 3. Aquiclude.

UH7b Moen sand and clay aquitard.Aquitards, by contrast, are compacted layers of clay, silt or rock that retard water flow underground; that is, they act as a barrier for groundwater. Aquitards separate aquifers and partially disconnect the flow of water underground. Also known as cap rocks, aquitards limit and direct the surface water which seeps down and replenishes aquifers.
