Unconfined and Deep Confined Aquifer Interactions Evaluated by Isotopic Techniques San Luis Valley, ColoradoO compositions and distributions, suggest that mountain front recharge is the principle recharge mechanism for the upper and lower confined aquifers with travel times in the northern valley of more ...
Mixed confined and unconfined groundwater flow occurs in a bounded initially dry aquifer when the hydraulic head at the side boundary suddenly rises above the elevation of the aquifer's top boundary. The flow problem as modelled by the Boussinesq equation is non-trivial because of the involvement...
A three dimensional finite element model for fluid flow and transport in confined or unconfined aquifer : F. Jacob, J. M. Crolet, P. Lesaint & J. Mania, in: Water pollution III: modeling, measuring and prediction, ed L.C. Wrobel & P. Latinopoulos, (Computational Mechanics Publications)...
aAs mentioned earlier, beneath the lower Guadal- quivir valley there is an extensive detritic aquifer some 3,000 km ~ in area. Approximately half of this aquifer is unconfined and receives direct recharge from rain- fall. The other half remains confined beneath the muds and clays of the ...
Widespread groundwater overdraft in alluvial aquifer systems like the Central Valley (CV) in California, USA, has increased interest in managed aquifer rec
SummaryA metagenomic analysis of two aquifer systems located under a dairy farming region was performed to examine to what extent the composition and function of microbial communities varies between confined and surface-influenced unconfined groundwater ecosystems. A fundamental shift in taxa was seen ...

Groundwater samples were collected from seven boreholes: two from unconfined aquifer and five from confined aquifer systems during the wet season of 2017year. ORP and DO indicates thatthe groundwater of the unconfined aquifer exists in the oxidization condition and that of the confined aquifer ...
