Complex Geometry of Depositional Facies Within a Coastal Aquifer System: Three-dimensional Mapping of Confining Layers and Hydrogeologic ImplicationsCoastal aquifers in California present numerous groundwater management challenges stemming from population pressure, environmental impacts, and seawater intrusion, but...
Artesian water: Artesian water comes from an artesian well, which draws water from a confined aquifer (an underground, porous rock or sand formation that bears water and is under pressure from a layer of rock or clay above it). The pressure from the confining layer forces the water from the...
An aquitard exists between the leaky-confined aquifer and the overlying unconfined aquifer. The aquitard has a substantially smaller low permeability than either the leaky-confined aquifer or the unconfined aquifer and its thickness is much smaller as well as compared to the thicknesses of its ...
Furthermore, the lake’s residue’s estimated age is ~1.1 Ga (~2.3 Ga post-peak aquifer drainage during the Late Hesperian), enhancing the prospects for organic matter preservation. This deposit’s inferred fine-grained composition, coupled with the presence of coexisting mud volcanoes and ...

The interaction between geothermal and mechanical processes can be considered relevant for the quantification of scenarios of slope stability in volcanic i
At the same time, grouting modification was applied to the weakly water-bearing strata above the aquifer, transforming the aquifer into an impermeable layer, thereby increasing the thickness of the water-resistant layer and cutting off the communication path between the confined water and the goaf....
The aquifer is unconfined in the outcrop area on its western edge and the surrounding area, and is confined or leaky as it gradually dips towards the north and north-east under less permeable formations [UNESCWA, 2013]. The confining layer is overlain by shallower aquifers in the Tabuk area...
(Lapanje et al.2009) are also important for the outflow of thermal water; however, in this confined aquifer, the heat transport mechanism can be interpreted as conductive. Recently, Szijártó et al. (2021) found that the influence of conductive faults on the heat flux and the recharge ...
To the western part of the basin, a thick basal clay aquitard is overlain by a single semi-confined continuous sand aquifer which breaks up into multiple aquifer units seperated by clay aquitards towards the southern end [82]. The delta plains of the Ganges-Bramhaputra-Meghna river system, ...
