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...
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,...
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...
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...
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...
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...
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....
