Changes in hyporheic exchange flow following experimental large wood removal in a second order, low gradient stream, Chichagof Island, AK

Creator:: La Nier, Justin
Abstract:: Hyporheic Exchange Flow (HEF) is driven by head gradients defined by the hydro-topography of the stream surface, which is controlled by the particular geomorphology of the stream. We quantified the impact of large wood, which typically exerts a strong control on stream morphology, on HEF in a second order, low...

Microwave scattering from surf zone waves

Creator:: Catalán Mondaca, Patricio A.
Abstract:: Wave breaking in the surf zone is an important forcing mechanism on the generation of nearshore currents and in the driving of sediment transport. At the same time, wave breaking can have significant spatial and temporal variability that needs to be accounted for in the description of nearshore processes. Remote...

The Impact of Internet and Videogame Use on College Student Development

Creator:: Calhoun, Benjamin W.
Abstract:: In recent decades, there has been a tremendous change in the college student experience. In many ways this change has been driven by developments in technology, which have in turn changed the way students conduct research, socialize, and recreate. This thesis seeks to gain an understanding as to how Internet...

Development of biomimetic control strategies for the optimal use of renewable sources and energy storage systems

Creator:: Hapke, Hannes Max
Abstract:: In the year 2007, the worldwide energy consumption accumulated to a total of 16.5 billion MWh. While the resources of conventional energy production cause environmental damage, renewable energy sources like solar or wind power offer a solution to substitute for coal or nuclear generated power. Countries like Denmark and Spain...

Towards reliable and survivable ocean wave energy converters

Creator:: Brown, Adam C.
Abstract:: Ocean wave energy is a new and developing field of renewable energy with great potential. The energy contained in one meter of an average wave off the coast of Newport Oregon could supply dozens of homes with electricity. However, ocean waves are usually quite irregular which leads to large bursts...

Phenotypic response and quantitative trait loci for resistance to Cephalosporium gramineum in winter wheat

Creator:: Quincke, Martin C.
Abstract:: Cephalosporium stripe (Cephalosporium gramineum) is an important disease limiting adoption of conservation tillage practices in the Pacific Northwest. The disease can cause severe loss of grain yield and quality in winter wheat (Triticum aestivum L.). Modified cultural practices can reduce disease incidence, but are not always dependable because of variation...

Understanding the impact of climate change on snowpack extent and measurement in the Columbia River Basin and nested sub basins

Creator:: Brown, Aimee Lyn
Abstract:: Shifting climate patterns in the Columbia River basin are affecting snow pack, and, as a result, stream flow throughout the region. In the Oregon Cascades, ever growing populations, and their associated activities, place increasing stress on an already over allocated hydrologic system. Political pressures, including the possibility of renegotiation or...

The value of short run in-stream temperature forecasts : an application to salmonids in the Klamath and John Day Rivers

Creator:: Huang, Biao
Abstract:: Water temperature is an important measure of water quality, as well as a dominant factor affecting aquatic life within the stream environment. Elevated water temperatures can decrease the survival rate of fish in each life stage. Cold water species, such as salmonids, are particularly susceptible to elevated water temperatures. For...

On the estimation and application of spatial and temporal autocorrelation in headwater streams

Creator:: Som, Nicholas A.
Abstract:: This collection of three manuscripts serves to improve methods for collecting, interpreting, and utilizing autocorrelated data from headwater stream networks. Each stream network is comprised of linear segments. These segments lie within a unique branching structure that connects the segments via flowing water, and the connectivity provided by water varies...

A perceived-risk curriculum for at-risk learners

Creator:: Kash, Laurel Renee
Abstract:: Although perceived-risk curriculum, that is, where the learner experiences effects of eustress (positive stress), has been used in Arts or outdoor activities, it has not been used in school classrooms. Milkman’s 1996 studies of after-school Project Self Discovery demonstrated that at-risk students lessened their adverse risky behaviors, such as substance...
