An investigation of multiphase flow in complex microchannel geometries for hemodialysis systems using residence time distribution analysis

Creator:: Coblyn, Matthew Y.
Abstract:: There are approximately 2.2 million cases of End-stage Renal Disease (ESRD) worldwide and current hemodialysis treatment is costly and ultimately insufficient compared to kidney transplantation. There is a strong need to arrive at a better solution for treating ESRD. Microchannel-based hemodialysis is one proposed option, already shown to have improved...

Transboundary groundwater : geopolitical consequences, commons sense, and the law of the hidden sea

Creator:: Jarvis, William Todd
Abstract:: With 97% of the world’s freshwater resources stored underground, the connection between groundwater resources to the metrics of space, scale and time common to the geographic study of natural resources has not been extensively investigated by geographers. While nearly 240 transboundary aquifers are mapped across the world, a potential “tragedy”...

Forensic Hydrogeography : Assessing Groundwater Arsenic Concentrations and Testing Methods within the Harney Basin, Oregon

Creator:: Smitherman, Lauren L.
Abstract:: Harney County contains defining characteristics of regions containing arsenic within the groundwater such as its location in the western United States, unique closed basin geography, complex geology, and seasonal groundwater level fluctuations. Confirmation of arsenic concentrations above the Maximum Contaminant Level Drinking Water Standard of 10 μg/L has been observed...

Drop it like it’s Hot : Combining DTS and Temperature Modeling to Evaluate Stream Restoration on the Middle Fork of the John Day River

Creator:: Hall, Austin
Abstract:: Temperature is a key factor for salmonid health and is an important restoration metric on the Middle Fork of the John Day River in northeast Oregon. In the past century, dredge mining, deforestation, and overgrazing have degraded stream habitat and resulted in greater daytime stream temperatures in the region. Recent...

Chemical and isotopic patterns of nitrate variability in the southern Willamette Valley, Oregon

Creator:: Vick, Christopher Flanders
Abstract:: A relatively stable, persistent and historical problem with elevated NO₃⁻ concentrations in rural drinking wells in the southern Willamette Valley, Oregon is evident. What is the origin of NO₃⁻ in rural drinking water wells in this area? The answer to the question is not simple. Many non-point sources contribute to...

Temperature and infiltration characterization of a constructed wetland for wastewater treatment

Creator:: Gregory, Christopher T.
Abstract:: The City of Woodburn, Oregon's Wastewater Treatment Plant (WWTP) has been investigating several natural alternatives for improving effluent quality. Based on its current National Pollution Discharge Elimination System (NPDES) permit, the WWTP will require additional reduction of temperature and ammonia levels in the summer, especially in the critical month of...

Investigation of the hydraulic, physical, and chemical buffering capacity of Missoula Flood Deposits for water quality and supply in the Willamette Valley of Oregon

Creator:: Iverson, Justin
Abstract:: The Willamette Silt is a surficial geologic unit composed of successive Missoula Flood Deposits that underlies 3100 km2 (1200 mil) of arable land in the Willamette Valley of Oregon. The Willamette Silt protects the underlying regionally important Willamette Aquifer from agricultural contamination while acting as a semi-confining unit and a...

Monitoring of groundwater and surfacewater interactions on the Walla Walla River, Oregon for the purpose of restoring in-stream flows for ESA listed fish habitat

Creator:: Metcalf, Becky Elise
Abstract:: In an effort to restore summer flows in the Walla Walla River to provide passage and habitat for ESA (endangered species act) listed bull and steelhead trout irrigation districts left 13 cubic-feet-per-second (c.f.s) (0.37 m ³/s) in the main channel during irrigation season (May-November) for the first time in over...

Infiltration and temperature characterization of a wastewater hyporheic discharge system

Creator:: Stewart, Ryan D.
Abstract:: The Clean Water Act imposes Total Maximum Daily Load (TMDL) limits on pollutant concentrations within wastewater effluent; in Oregon, thermal discharge is one of the pollutants subject to regulation. The City of Woodburn, Oregon, funded a series of pilot scale studies to investigate the utility of natural systems to reduce...

An investigation of the distribution and abundance of ichthyoplankton and juvenile benthic fishes in relation to nearshore hypoxia within the Northern California Current system

Creator:: Johnson, Angela M.
Abstract:: Nearshore hypoxia within the Northern California Current (NCC) system is a seasonal phenomenon caused by coastal upwelling and occurs mainly during late-summer and early fall. The effects of low oxygen levels on fish and invertebrate communities, particularly during early-life history stages, however, are poorly known for this area. I investigated...
