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...
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 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

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...
