Modeling the effect of longwave radiation from solar panels on soil moisture

Creator:: Shepard, Laurel A.
Abstract:: Agrivoltaics, which integrates photovoltaic power production with agriculture in the same plot of land, has the potential to reduce land competition and crop irrigation. To optimize agrivoltaic systems for crop growth, energy pathways must be characterized. While solar panels shade the crops, they also emit longwave radiation. At the end...

The Relationship between Hydroregime and Coho Salmon (Oncorhynchus kisutch) Spawning in Three Streams of the Smith River Watershed, Oregon

Creator:: Baxter, Mackenzie R.
Abstract:: Migration and spawning phenology of Pacific Salmon is linked to the hydroregime, and thought to be triggered by increases in river discharge and decreases in water temperature. However, little data exists that describes direct fine-scale linkages between the hydroregime and spawning in Coho Salmon. This study evaluated the spatial and...

Characterizing adaptive governance capacity : A case study of the Willamette River Basin

Creator:: Jones, Ingria
Abstract:: The Willamette River Basin supports 70% of Oregon’s population and contains the richest native fish fauna in the state, (Hulse, Gregory, & Baker, 2002). The Basin is facing changes that stress its water management regimes. Is the Basin’s water management regime able to adapt in the face of these changes?...

Exploring mechanisms that drive the development of reversible soil hydrophobicity

Creator:: Woolverton, Priscilla B.
Abstract:: This study focuses on one widespread characteristic of poor soil quality: hydrophobic soil. Previous research has produced conclusive evidence to show that soil hydrophobicity is affected by soil organic matter (SOM) and soil water content (WC). Hydrophobicity that responds to changes in WC is a unique form of surface hydrophobicity...

Stream channel stability and sensitivity to landscape history and land use changes in Kelley Creek, Portland, Oregon

Creator:: Murphy, Yarrow M.
Abstract:: This study examines stream channel erosion processes in a small urbanizing watershed influenced by deposits of the Columbia Basin catastrophic floods: Kelley Creek, a 12-km² tributary of Johnson Creek, located just east of Portland, Oregon. Information on landscape history, stream channels, and sediment dynamics was compiled. The effects of future...

An exploratory study of the social factors of small dam removal : Chiloquin Dam at Sprague River Mile 0.87, Oregon

Creator:: Hatch, Jason M.
Abstract:: Several reports related to dams and dam removal have been released this decade by non-governmental organizations including Dam Removal: Science and Decision Making by The Heinz Center which focused on small dams, since most of the dams removed to date as well as those likely to be removed in the...

Will we need to change the rules : assessing the implications of climate change for dam operations in Oregon's McKenzie River Basin

Creator:: Danner, Allison G.
Abstract:: Dams and reservoirs are important components of water resource management systems, but their operational sensitivity to streamflow variability may make them vulnerable to climate change. Climate change is likely to affect the magnitude and timing of streamflow, motivating the assessment of potential impacts on dams and reservoirs. Here I examine...

Measuring sediment transport rates using tracer gravel and RFID technology

Creator:: Lewis, Logan L.
Abstract:: Rates of sediment transport were determined using tracer gravel and a RFID antenna array at Oak Creek (Oregon) to compare a new method with an existing transport relation created from data previously collected in the same study reach. Close to 3,000 tracers were deployed throughout the study reach and were...

Temporal and Spatial Variability of Channel Adjustment to Floods in a 5th order Forested Mountain Stream

Creator:: Cromer, Leah
Abstract:: Mountain rivers are important aquatic ecosystems that regulate sediment and water delivery to higher order streams. While previous studies have debated the roles of hillslope and fluvial processes in driving change in channel morphology of mountain rivers, few have examined how these processes influence channel response over longer timescales. The...

Long-Term Stream Channel Response to a Large Flood in a Forested Mountain Watershed

Creator:: Goodman, Arianna C.
Abstract:: There is still scholarly debate on the impacts of large floods on the geomorphic evolution of mountain rivers. Understating the geomorphic effects of large flows in mountain rivers is challenging given the hydraulic complexity of these systems and the inherent unpredictability of large floods. Prior work has demonstrated that extreme...
