Tidal response of groundwater in a leaky aquifer: application to Oklahoma [PDF]

open access: yesWater Resources Research, 2018
Quantitative interpretation of the tidal response of water levels measured in wells has long been made either with a model for perfectly confined aquifers or with a model for purely unconfined aquifers. However, many aquifers may be neither totally confined nor purely unconfined at the frequencies of tidal loading but behave somewhere between the two ...

Saturated-Unsaturated flow in a Compressible Leaky-unconfined Aquifer [PDF]

open access: yesAWR-11-418 2012, 2011
An analytical solution is developed for three-dimensional flow towards a partially penetrating large-diameter well in an unconfined aquifer bounded below by an aquitard of finite or semi-infinite extent. The analytical solution is derived using Laplace and Hankel transforms, then inverted numerically.

Well Design as a Factor Contributing to Loss of Water from the Floridan Aquifer, Eastern Clay County, Florida [PDF]

open access: bronze, 1962
A number of wells penetrating the Floridan aquifer in eastern Clay County were found to be losing water to permeable zones above this aquifer. A differential in artesian pressure was observed in closely spaced wells of similar depth.

Impact of pressure dissipation on fluid injection into layered aquifers [PDF]

open access: yesJ. Fluid Mech. 877 (2019) 214-238, 2019
Carbon dioxide (CO2) capture and subsurface storage is one method for reducing anthropogenic CO2 emissions to mitigate climate change. It is well known that large-scale fluid injection into the subsurface leads to a buildup in pressure that gradually spreads and dissipates through lateral and vertical migration of water.

Fracture Propagation Driven by Fluid Outflow from a Low-permeability Aquifer [PDF]

open access: yesTransport in Porous Media 2013, 100 (1), 69-92, 2012
Deep saline aquifers are promising geological reservoirs for CO2 sequestration if they do not leak. The absence of leakage is provided by the caprock integrity. However, CO2 injection operations may change the geomechanical stresses and cause fracturing of the caprock.

Leveraging Big Data to Preserve the Mississippi River Valley Alluvial Aquifer: A Blueprint for the National Center for Alluvial Aquifer Research

open access: yesLand, 2022
The challenge of a depleting Mississippi River Valley Alluvial Aquifer (MRVAA) requires reducing groundwater withdrawal for irrigation, increasing aquifer recharge, and protecting water quality for sustainable water use.

Geostatistical spatial projection of geophysical parameters for practical aquifer mapping

open access: yesScientific Reports, 2022
Dense data acquisition for 3-D high-resolution aquifer mapping through heliborne transient electromagnetic (HTEM) survey is continually not possible due to various technical and administrative constraints.

Positive Mathematical Programming to Model Regional or Basin-Wide Implications of Producer Adoption of Practices Emerging from Plot-Based Research

open access: yesAgronomy, 2021
A method for calibrating models of agricultural production and resource use for policy analysis is proposed to leverage multidisciplinary agricultural research at the National Center for Alluvial Aquifer Research (NCAAR).

Perceptions of Irrigation Water Management Practices in the Mississippi Delta

open access: yesAgronomy, 2022
The Mississippi River Valley Alluvial Aquifer (MRVAA) is being depleted, and practices that improve water stewardship have been developed to reduce drawdown. This study assesses how Mississippi Delta producers changed their perceptions of these practices

Using Analytical Hierarchy Process and Multi-Influencing Factors to Map Groundwater Recharge Zones in a Semi-Arid Mediterranean Coastal Aquifer

open access: yesWater, 2020
Mapping groundwater recharge zones (GWRZs) is essential for planning artificial recharge programs to mitigate groundwater decline and saltwater intrusion into coastal aquifers.
