Saturation, morphology, and topology of nonwetting phase fluid in bentheimer sandstone; application to geologic sequestration of supercritical CO2

Creator:: Herring, Anna L.
Abstract:: This work examines the impact of a viscosity force parameter, fluid velocity, and a capillary force parameter, interfacial tension, on the saturation, morphology, and topology of NW fluid in Bentheimer sandstone after primary imbibition, drainage, and secondary imbibition. Brine and air (used as a proxy for supercritical CO₂) flow experiments...

Environmental Impacts of Renewable Energy (solar and wind) on Water, Food and Energy Nexus

Creator:: Hassanpour Adeh, Elnaz
Abstract:: Rapid increasing of renewable energies and the knowledge about their environmental effects are very limited. As a result, the renewable energies (e.g. solar or wind energies) will play a vital role in the future because it is well accepted by environmental friendly industries. This dissertation presents the modeling, data analysis...

An Experimental Investigation of Interstitial Air Movement in Seasonal Snow

Creator:: Drake, Stephen A.
Abstract:: Atmospheric pressure changes do not stop at the permeable snow surface but rather propagate into it. These pressure changes range from high-amplitude, low-frequency events caused by seasonal cycles and synoptic weather systems to small-amplitude, high-frequency events caused by topographic features and turbulence. The effect of pressure changes on interstitial air...

Horizontal and vertical distribution of juvenile pollock (Theragra chalcogramma) in the southeastern Bering Sea

Creator:: McIntosh, Neal E.
Abstract:: Juvenile walleye pollock (Theragra chalcogramma) are one of the primary prey items for bird and mammal predators in the Bering Sea and support a large commercial fishery. An understanding of the environmental factors that determine the horizontal and vertical distribution of juvenile pollock is needed to estimate the effects that...

Quantitative, multi-spectral, light-transmission imaging of colloid transport in porous media at the meso scale

Creator:: Kraft, Erika Lorna
Abstract:: Colloids, particles smaller than ten microns in diameter, are ubiquitous in the subsurface. Colloids have an effect on the transport of contaminants that bind to their surfaces, and can reduce the permeability of aquifer materials through deposition. Some microorganisms, including pathogens, are also transported in the subsurface as colloids. The...

Demonstration of fiber optic distributed temperature sensing to differentiate cold water refuge between ground water inflows and hyporheic exchange

Creator:: Collier, Michael W.
Abstract:: Recent developments in Distributed Temperature Sensing (DTS) have allowed new insight into the surface-to-ground water interaction. The continuous temperature measurement by the DTS allows for cool water inflows to be located during warm summer months. These cool water inflows can then be differentiated between ground water and hyporheic exchange. The...

Impact of exotic Ponderosa pine (Pinus ponderosa Doug. ex Laws.) plantations on water resources in northwestern Patagonia, Argentina

Creator:: Licata, Julian A.
Abstract:: Exotic ponderosa pine (Pinus ponderosa Doug. ex Lawson) plantations are being planted within the natural distribution area of cordilleran cypress (Austrocedrus chilensis (D.Don) Pic. Ser. et Bizzarri) in Patagonia, Argentina. The productivity of these exotic plantations is much greater than that of native forests, suggesting greater water use. Before these...

The influence of contemporary forest harvesting on summer stream temperatures in headwater streams of Hinkle Creek, Oregon

Creator:: Kibler, Kelly Maren
Abstract:: Stream temperature is a water quality parameter that directly influences the quality of aquatic habitat, particularly for cold-water species such as Pacific salmonids. Forest harvesting adjacent to a stream can increase the amount of solar radiation the stream receives, which can elevate stream temperatures and impair aquatic habitat. Oregon Forest...

Construction, Degradation, and Restoration of Wet Meadow Ecosystems in Semi-arid Landscapes, Northern Great Basin, USA

Creator:: Nash, Caroline S.
Abstract:: Wet meadow ecosystems are a useful natural laboratory in which to explore feedbacks between biogenic and geologic controls on valley bottom landforms. Characterized by flat valley floors flanked by higher-gradient hillslopes, these meadows are singular both in that they represent depositional features in what is primarily an erosional environment, and...

Mass-spectrometric Methods for Quantitative Proteomics and Post-translational Modification Mapping

Creator:: Motorykin, Ievgen
Abstract:: Signal transduction within and between cells is at the core of biological activity in all living systems. Signaling networks are required for regulating biological functions, including growth, development and survival. Deregulation of signaling cascades has been linked to chronic and acute diseases and disorders This thesis focuses on mass spectrometry...
