A promising way to mitigate global warming is to sequester CO2 in deep saline aquifers. In order to determine which aquifers are the best for sequestration, it is helpful to estimate how much CO2 they can store. Currently, this is difficult because both the pressure buildup from injection and the volume of available pore space have been identified as constraints, but have not been compared to d...

We present a semi-analytical solution for the transient streaming potential response of a confined aquifer to pumping at a constant rate through a fully-penetrating line sink. Confined aquifer flow is assumed to occur without fluid leakage from the confining units and is thus described by the solution of Theis (1935). The confining units, which are typically more electrically conductive than th...

This study presents a semi-analytical solution for the problem of leakage in an unconfined aquifer bounded below by an aquitard of finite or semi-infinite extent. The homogeneous anisotropic unconfined aquifer of infinite radial extent is pumped continuously at a constant rate from a well of infinitesimal radius. The aquitard is also homogeneous , anisotropic and of infinite radial extent. Flow...

Modeling the geologic architecture of an aquifer and visualizing its three-dimensional structure require lithologic data recorded during well drilling. Uncertainties in layer boundaries arise due to questionable quality of drilling records, mixing during the drilling process, which results in blurred contacts, and natural heterogeneity of the geologic materials. An approach for modeling and vis...

Groundwater is the only source of water for domestic as well as agricultural purposes in the sand aquifer in between sea and lagoon configuration typically found in the eastern Sri Lanka. This study was carried out to estimate the safe yield and assess the vulnerability of the sandy aquifer on the eastern coastal belt of Sri Lanka by rapid urbanization, agriculture and as well as climate change...

Groundwater systems in the intermediate to deep subsurface of southern Ontario are poorly understood, despite their value for a number societal uses. A regional hydrostratigraphic framework is necessary precursor improving our understanding groundwater and enabling development 3-D model visualize these systems. This study compilation integration published unpublished geological, hydrogeological...

The key processes responsible for the rise in groundwater salinization Mio–Pliocene aquifer system of Sousse (Tunisia, eastern coastline) were identified through a multidisciplinary approach based on use geochemical, stable (2H, 13C, 18O and 37Cl) radioactive (3H 14C) isotope methods. In study region, mineralization groundwaters is related to water–rock interaction ascribed dissolution minerals...

The Pearl River Delta (PRD), located in the coastal area of South China, contains a large confined Quaternary aquifer. This aquifer has been identified to have high concentrations of total dissolved solids–ranging from 1 g/l in the inland area to 26.8 g/l near the southeast shoreline. This work aims to investigate the origin of groundwater salinity and the major hydrogeochemical processes contr...

This uniquely designed study investigates a fundamental issue—the feasibility of predicting stream depletion rates using linear uniform two-dimensional models. Required input for these models includes the hydraulic parameter estimates of the aquifer and the stream–aquifer interface, which may be obtainable through pumping test data analysis. This study utilizes pumping test data collected near ...
