Numerous studies have explored how alluvial channel size and morphology are adjusted to different sediment and flow conditions, yet we still know very little about how and to what degree the flow regime controls channel form and processes. We use the term ‘channel form’ to refer to the size and...
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...
The relationship between carbon burial and sedimentation in reservoirs is unknown, exposing gaps in our fundamental understanding of the transport, processing, and deposition of sediment and organic matter in fluvial and lacustrine systems and contributing to uncertainty in our understanding of the net impact of dams to the global carbon...
The purpose of this study was to identity clothing
purchasing habits of women 60 years of age and over.
Data for this study were obtained from a questionnaire
administered to 94 women, 60 years of age and over, living
in Portland, Corvallis, and Eugene, Oregon. The sample was
analyzed on...
The purpose of this study was to compare the performance of
hosiery made from a new fiber, polypropylene, with the performance
of hosiery made from a better known fiber, nylon, and to get
some indication of consumer reaction to a new textile product.
Information was obtained through two wear tests...
With the increased variety and use of lining fabrics, consumers
have become concerned over choices for lining fabrics which have
good serviceability properties. The major purpose of this study was
to secure some information on the physical properties of lining fabrics
to help consumers in the selection of lining fabrics...
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...

Dams and reservoirs are important components of water resource management
A first-order approximation is made of the frequency and magnitude of bedload transport downstream of the Pelton-Round Butte Dam Complex, lower Deschutes River, Oregon with implications for salmonid spawning habitat. Field measurements of channel hydraulics, geometry, and particle size were combined with one-dimensional hydraulic and bedload transport models to determine...
Although there has been extensive research on the geomorphic and ecologic role of
large woody debris (LWD) in streams, the dynamics of LWD in streams are poorly
known due to various measurement difficulties during floods. In this thesis I present the
results of two flume experiments on the dynamics of...
