Using GPS to Quantify Three Dimensional Storage and Aquifer Deformation in the Virgin River Valley, NV
… the significance of horizontal strain during an aquifer test. The hydraulic heads in the aquifer were monitored within a meter of the municipal pumping well used for the aquifer test and also at a distance of approximately 1,470 meters from the pumping well. Aquifer deformation in the horizontal …

HYDROGEOLOGIC PROPERTY ESTIMATION IN PLATE BOUNDARY OBSERVATORY BOREHOLES USING TIDAL RESPONSE ANALYSIS
… to other regional studies and traditional aquifer test determinations available for one borehole. No obvious trends with distance from large faults are observed, in contrast with previously determined variations in the pressure response to seismic waves, and only one borehole exhibits …

Evaluation of a Fractional Theis Equation
… used solution for determination of confined aquifer parameters. Because each aquifer is a unique system, sometimes an aquifer cannot accurately be described with the assumptions of the Theis solution. To offer a more general solution for aquifers where piezometric head at a given position is …

Hydrogeology and groundwater geochemistry of two glacigenic aquitard/aquifer systems in north-central and south-central Minnesota
<p>Buried glacial aquifers in Minnesota contribute drinking water to many communities throughout the state. Vertical leakage through overlying till aquitards is largely unknown, causing uncertainty in predicting aquifer sustainability. As part of a study of confined aquifer sustainability, the U.S. …

Development of risk-based groundwater operating rules: a case study of Siloam Village, South Africa
… curve matching was used to identify appropriate aquifer models and test solutions for estimating hydraulic characteristics (storativity, transmissivity and hydraulic conductivity) based on Aquifer Test Solver (AQTESOLV) Pro version 4.5. Limited groundwater levels and rainfall data were infilled …

Aquifer Characterization in the Blue Ridge Physiographic Province
… and porous regolith with a water-table aquifer that slowly supplies water downward to the underlying variably fractured crystalline bedrock. In these models, interconnected fractures in the crystalline bedrock act as conduits for predominantly downward vertical and limited horizontal …

Use of hydraulic tests to identify conceptual models of heterogeneity for fractured rock aquifers
Important aquifers, petroleum reservoirs, geothermal reservoirs, and waste disposal sites throughout the world are located in fractured rock formations. Responsible management of these resources and sites requires appropriate field characterization studies and modeling techniques to assess the …

Investigations on mobility of carbon colloid supported nanoscale zero-valent iron (nZVI) for groundwater remediation
… experiment in a 1.2-m-sized two-dimensional aquifer tank experiment, which was filled with granular porous media. Further, a field experiment was performed in a natural aquifer system with a targeted transport distance of 5.3 m. Parallel to these investigations, alternative methods for …

A method using drawdown derivatives to estimate aquifer properties near active groundwater production well fields
… of a new inverse modeling approach to estimate aquifer properties in the vicinity of continuously-pumped well fields. The specific emphasis is on deep bedrock aquifers where monitoring well installation is often not practicable due to high drilling costs. In these settings, water levels from …
