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...
This thesis is a documentation of a selected number of nineteenth century quilts studied by the investigator in the Willamette Valley.
The quilts were located in museums and in individual's homes. A questionnaire, that was developed for this study of quilts, was
filled out as each quilt was examined. Slides...
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...
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
The objective of this study is to analyze empirically the demand
structure for the following important farm production inputs in
Oregon: hired labor, chemical fertilizer, farm machinery, repairs
and operating costs of motor vehicles and other machinery designated
as "machinery supplies," purchased feed and miscellaneous inputs.
Twenty-year data (1950-69 except...
Concern over the apparent disparity between the farm use value
and current market value of property in agricultural areas continues
to remain a source of concern in many areas. This concern has
intensified in recent years, particularly in those agricultural areas
situated near urban centers and recreational areas.
The main...
Thailand has been recognized as a rice-producing country from time immemorial. Besides being a staple food, rice has been the exported product that earned the most foreign exchange which has been badly needed for the economic development of the country. Since the end of the second world war, many countries...
The Federal Republic of Nigeria, on the west coast of the continent of Africa, is divided into four Regions: Northern, Western, Midwestern and Eastern. The Federal Capital of the country is Lagos. Eastern Nigeria occupies the south-eastern portion of the country, nearest to the Federal Republic of Cameroun.
The propensity...
The Petchburi Irrigation Project was built in the southern part of
the Central Plain of Thailand in 1942. The purpose of the project was
to divert water from the Petchburi River to irrigate the principal part
of the Petchburi Plain where lands were used for rice and upland crop
production....
Use of federal lands for commercial and recreational activities
contributes significantly to the economic stability of many rural
areas. Recent increases in demand for recreational use have created
conflicts between uses and among users. Some are questioning the
use of public land for private gain. The seemingly low grazing fees...
A study was made to determine and examine the economics of
the mechanical harvest of tomatoes in the Salinas Valley of California.
To achieve this objective, it was necessary to detail the related cultural requirements of the machine harvested crop to the extent they budget technique, two economic models; one...
Geomorphic change along the lower Clackamas River is occurring at
a millennial scale due to climate change; a decadal scale as a result River
Mill Dam operation; and at an annual scale since 1996 due to a meander
cutoff. Channel response to these three mechanisms is incision.
Holocene strath terraces,...
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...
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...
Debris flow initiation is controlled by a complex interaction of geology, geomorphology, climate, and weather. In the Cascade Range of Pacific Northwest and mountainous areas globally, patterns of temperature and precipitation are being altered by climate change, which may in turn impact debris flow initiation. Temperature has increased and patterns...
Despite the importance of rain and snowmelt in causing peakflows in the Pacific
Northwest, the interactive effects of a snowpack and watershed physiography on
streamflow are largely undocumented. This study investigated the influence of soil and
snowpack moisture on peakflow hydrograph shape in three small (< 60 ha) control sub-watersheds...
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...
