Assessment Of Groundwater Resources Using Remote Sensing And Gis, Muna Khalil Al Hammadi

Theses

Geographical Information Systems and Remote Sensing have witnessed an enormous interest in various applications related to geology, hydrology, hydrogeology, and water resources. The use of GIS and remote sensing has become a common practice worldwide. The UAE is no exception. The study of groundwater resources and its sustainability is of prime concern for authorities in the UAE. Although, groundwater may not be suitable, in most cases, for drinking and other potable purposes, it represents the main source for irrigation in the country. About 85% of the total water consumption in the UAE is groundwater.

This study is devoted to the …

Simulation Of Groundwater Flow In Cache Valley, Utah And Idaho, Barry Myers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A groundwater model of Cache Valley was created using MODFLOW. Steady-state calibration of the model demonstrated that recharge to the lower confined aquifer may occur along the margin of the valley that borders the Wellsville Mountains and the Bear River Range. Steady-state calibration also showed that discharge from the unconfined aquifer may occur along the eastern and western margins of the valley in both the Utah and the Idaho portions of the valley.

Two simulations were run with increased pumping of 3 5 cubic feet per second (1 cubic meter per second) from the principal aquifer. The first simulation was …

A Δ18o Calibrated Compartmental Mixing Cell Model Of Groundwater Flow In The Roswell Basin, Southeastern New Mexico, Michael M. Gabora

Water Resources Professional Project Reports

For this project fifty-four water samples were collected from sites throughout the Roswell groundwater basin in southeastern New Mexico that were previously sampled by Hoy and Gross in the 1970's. These data sets were used to evaluate the transience of δ18O values in the basin in hopes of simulating transient conditions with a compartmental mixing cell model. No long-term trend in the data was established. A compartmental mixing cell model was developed and calibrated with the spatial distribution of δ18O. The model was run using the steady-state simulation and produced estimates of groundwater flow paths, volumetric flow rates, recharge rates …

Assessment Of Groundwater Resources In Selected Areas Of Al Ain In The U.A.E., Fatma Abdullatif Al Shahi

Theses

The sustainable development of any region depends on the availability of water resources. In arid and semi-arid regions, the shortage in freshwater resources constitutes the major constraint against the expansion in agricultural and industrial activities. Therefore, every possible effort should be made to assess, develop and sustain the limited freshwater water resource in such regions.

The United Arab Emirates (UAE) is located in an arid region, where the climate is harsh and the renewable freshwater resources are very limited. Despite the severe shortage in water resources, water is misused and sometimes wasted. The per capita daily consumption in the UAE …

Thermochronological Evolution Of Calcite Formation At The Potential Yucca Mountain Repository Site, Nevada: Part 2 Fluid Inclusion Analyses And Upb Dating, Jean S. Cline, Amy J. Smiecinski, Robert Bodnar

Publications (YM)

The presence of two-phase fluid inclusions in thin secondary mineral crusts at the potential Yucca Mountain nuclear waste repository has raised questions regarding the origin, timing, and temperature of past fluid flow through the repository horizon. The geologically recent passage of fluids with high temperatures would call into question the suitability of the site for the storage of high level nuclear waste. This study determined the thermal history of fluid flow through the site using fluid inclusion analyses and constrained the timing of thermal fluids by dating silica minerals spatially associated with the fluid inclusions using U-Pb techniques. Results provide …

Thermochronological Evolution Of Calcite Formation At The Proposed Yucca Mountain Repository Site, Nevada: Part 1, Secondary Mineral Paragenesis And Geochemistry, Jean S. Cline, Amy J. Smiecinski, Robert Bodnar

Publications (YM)

In the near future a decision will be made as to whether or not Yucca Mountain, 90 miles northwest of Las Vegas, Nevada is a suitable site for a permanent, underground, high level nuclear waste repository. A major factor in determining the suitability of Yucca Mountain as a repository is the potential for the site to be flooded by water during the regulatory lifetime. The current study was undertaken to examine the past fluid history at the site, to gain a better understanding of the possibility of flooding in the near geologic future. To estimate the past fluid flux into …

Depth Characterization Of Shallow Aquifers With Seismic Reflection, Part Ii—Prestack Depth Migration And Field Examples, John H. Bradford, D. S. Sawyer

CGISS Publications and Presentations

It is common in shallow seismic studies for the compressional-wave velocity in unconsolidated sediments to increase by a factor of four or more at the transition from dry or partial water saturation to full saturation. Under these conditions, conventional NMO velocity analysis fails and leads to large depth and layer thickness estimates if the Dix equation is assumed valid. Prestack depth migration (PSDM) is a means of improving image accuracy. A comparison of PSDM with conventional NMO processing for three field examples from differing hydrogeologic environments illustrates that PSDM can significantly improve image quality and accuracy.

Depth Characterization Of Shallow Aquifers With Seismic Reflection, Part I—The Failure Of Nmo Velocity Analysis And Quantitative Error Prediction, John H. Bradford

CGISS Publications and Presentations

As seismic reflection data become more prevalent as input for quantitative environmental and engineering studies, there is a growing need to assess and improve the accuracy of reflection processing methodologies. It is common for compressional-wave velocities to increase by a factor of four or more where shallow, unconsolidated sediments change from a dry or partially watersaturated regime to full saturation. While this degree of velocity contrast is rare in conventional seismology, it is a common scenario in shallow environments and leads to significant problems when trying to record and interpret reflections within about the first 30 m below the water …

Groundwater Quality In Kentucky: Ph, R. Stephen Fisher

Information Circular--KGS

The parameter pH (the negative base-10 logarithm of hydrogen ion activity, measured in moles per liter) indicates whether a substance will behave as an acid or base. It is one of the most important parameters that describe groundwater quality, because pH largely controls the amount and chemical form of many organic and inorganic solutes in groundwater.

Groundwater Quality In Kentucky: Arsenic, R. Stephen Fisher

Information Circular--KGS

Arsenic is a naturally occurring element found in low concentrations in rocks, soils, water, plants, and animals (Nriagu, 1994 a, b). In Kentucky, arsenic is commonly found in iron sulfide minerals associated with coal deposits and black shales. Arsenic is released when iron sulfides oxidize during weathering. Once released, it is readily sorbed onto iron oxides and iron oxyhydroxides, which limits arsenic concentrations in the near-surface environment.
