[1] In this study, multiscale permeability upscaling is combined with a sensitivity study of model boundary condition to identify an optimal heterogeneity resolution in developing a reservoir model to represent a deep saline aquifer in CO2 storage simulation. A three‐ dimensional, fully heterogeneous reservoir model is built for a deep saline aquifer in western Wyoming, where each grid cell is ...

Coastal aquifers of Andhra Pradesh form a part of a discontinuous strip of alluvium along the East Coast of India. These aquifers comprise ridge like features generated by tidal action and the deltaic fluvial deposits. They show many of the characteristic morphological features of stream and deltaic sediments, like channel bars, levees, etc., Their maximum thickness is reported to be around 400...

The Tamarack State Wildlife Area in eastern Colorado is being investigated as a possible managed recharge project to redirect flows in the South Platte River for water quantity management. Two primary surface water/groundwater interactions exist at Tamarack: (1) between the South Platte River and alluvial aquifer and (2) between backwater sloughs, or secondary river channels, and the alluvial a...

This work used experimental and numerical methods to investigate seawater intrusion (SWI) in a complex heterogeneous laboratory-scale aquifer. We started the analysis with homogeneous isotropic aquifer as reference case, then moved layered aquifers. The study also investigated block-wise synthetic aquifers different configurations. wedge toe length generally decreased under conditions, while fr...

Imaging subsurface small-scale features and monitoring transport of tracer plumes at a fine resolution is interest to characterize processes in aquifers. Full-waveform inversion (FWI) crosshole ground penetrating radar (GPR) measurements enables aquifer characterization decimeter-scale resolution. The method produces images both relative dielectric permittivity (εr) bulk electrical conductivity...

Sea-tide effects on the fresh-saline water interface (FSI) in a stratified coastal aquifer are examined through laboratory experiments. The physical model, two-dimensional rectangular flow tank, is filled with layered aquifers and aquitards. serve as main entrances/exits of to/from system significant horizontal flows, creating unstable conditions heavier saline above lighter freshwater for shor...

Abstract—Adequate and reliable estimates of aquifer parameters are of utmost importance for proper management of vital groundwater resources. At present scenario, the ground water is polluted because of industrial waste disposed over the land and the contaminants are transported in the aquifer from one area to another area, which is depending on the characteristics of the aquifer and contaminan...

Groundwater in a coastal sand aquifer is enriched in arsenic as a result of historical discharges from an industrial facility on the central NSW coast. Subsequent investigations also identified arsenic in the soil within the saturated zone down-gradient of the source area. Arsenic concentrations in soil and groundwater decrease markedly along a narrow flow path towards a tidal river some 300 m ...
