Flow-Solute : A Tool for Exploring the Effects of Nitrogen Management in Alternative Future Scenarios

Creator:: Wentworth, Andrew Michael
Abstract:: Surface water quality is a growing concern in the Willamette River Basin and elsewhere. The region's growing population is dependent on the availability of clean water for drinking water, irrigation, wastewater dilution, and wildlife habitat. Watershed management to produce economic goods and environmental services requires an understanding of basic hydrologic...

Addressing Emerging Issues in Tropical Ecohydrology : A Combined Hydrometric and Isotopic Approach to Evaluate the Origin and Age of Water in a High-Elevation Tropical Ecosystem

Creator:: Mosquera, Giovanny M.
Abstract:: This thesis focuses on the identification of ecohydrological processes in nested system of catchments in a tropical alpine (the wet Andean páramo) ecosystem. We accomplish this by conducting a water stable isotopic characterization of water sources, an evaluation of the mean transit time (MTT) of streams waters, and the investigation...

Model assessment of the effects of land use change on hydrologic response

Creator:: Vache, Kellie B.
Abstract:: The effect of landuse change on the hydrologic, biogeochemical and ecological response of watersheds is a concern throughout the world. To help characterize the potential magnitude of such changes, and of the potential to remediate or avoid undesirable features, studies focused on the cumulative watershed effects of site level change...

Monitoring Streamflow Response to Effects of Climate Change in the Kenai Peninsula and Prince William Sound Region of Southcentral Alaska

Creator:: Anderson, Dean J.
Abstract:: This thesis explores the challenges of monitoring stream hydrology in a warmer and wetter climate in the Kenai Peninsula (KP) and Prince William Sound (PWS) region of Southcentral Alaska, located on the traditional territories of the Dena’ina, Ahtna, Alutiiq/Sugpiaq, and Eyak People. The physical and climatological extremes of this region...

The role of bedrock groundwater in rainfall-runoff response at hillslope and catchment scales

Creator:: Gabrielli, Christopher P.
Abstract:: Bedrock groundwater dynamics in headwater catchments are poorly understood and poorly characterized. Direct hydrometric measurements have been limited due to the logistical challenges associated with drilling through hard rock in steep, remote and often roadless terrain. Here we develop and use an inexpensive, portable bedrock drilling system to explore bedrock...

Traffic and greenhouse gas modeling in future land use development scenarios of Skagit County

Creator:: Mooney, Abraham A.
Abstract:: Energy use and greenhouse gas emissions are on the forefront of planning policy in the world today. In the U.S., the transportation sector accounts for 50 percent of greenhouse gas (GHG) emissions, the most of any single sector. State and local levels of government have been very proactive in the...

Forest Succession and Climate Change Effects on Long-Term Runoff Coefficients at Varying Timescales

Creator:: Crampe, Emily A.
Abstract:: Forest harvesting and climate change induced shifts in precipitation characteristics (i.e., intensity, type) may affect how water is partitioned on the landscape, with more water potentially being lost to evaporation or groundwater, and less water being partitioned into the stream. Long-term, paired watershed data allows us to assess these possible...

Characterization of Stormwater Runoff from a County Maintenance Facility and Evaluation of Temporal Performance of Bioswale in Its Treatment

Creator:: Gyawali, Kshitiz
Abstract:: In the last few decades, a lot of studies have been conducted to study about the quality of stormwater runoff from various sites and conditions. Highways, residential areas, and commercial sites are the focus of most of these studies while limited studies have done examination of stormwater from Maintenance and...

Africa-Appropriate Urban Stormwater Management: The State of the Art

Creator:: Kahsai, Simon K.
Abstract:: Urban development causes changes in the hydrology, increasing stormwater runoff volumes, which often leads to flooding and ecosystem degradation. This is a common phenomenon in most urban Africa, due to lack of stormwater drainage infrastructures. Green Infrastructure (GI) has been shown to be an effective approach to lessen the effects...

Laboratory observations and numerical modeling of the effects of an array of wave energy converters

Creator:: Porter, Aaron K.
Abstract:: This thesis investigates the effects of wave energy converters (WECs) on water waves through the analysis of extensive laboratory experiments, as well as subsequent numerical simulations. Data for the analysis was collected during the WEC-Array Experiments performed at the O.H. Hinsdale Wave Research Laboratory at Oregon State University, under co-operation...
