The scientific endeavors that took place at Hanford Engineer Works, beginning in World War II and continuing thereafter, are often overlooked in the literature on the Manhattan Project, the Atomic Energy Commission, and in regional histories. To historians of science, Hanford is described as an industrial facility that illustrates the...
The fractal dimension of measured ocean wave profiles is found to be in the range of 1.5-1.8. This non-integer dimension indicates the fractal nature of the waves. Standard formulations to analyze waves are based on a differential approach. Since fractals are non-differentiable, this formulation fails for waves with fractal characteristics....
Approximately $1 billion a year is spent on salmon in the Pacific
Northwest. Spending has escalated, yet the number of wild runs
placed under the protection of the Endangered Species Act has
increased, creating social and political controversy. For more than 100
years, salmon management in the Pacific Northwest has...
This study used contingent valuation techniques to model the probability of participation in Oregon's CREP as a function of the incentive payment and a vector of socio-economic variables. Possible reasons for non-participation were evaluated and landowner preferences for various program components were assessed. Recommendations for program improvement and implementation were...
A numerical model is developed to estimate wave forces on A-Jacks armor units. The forces include drag, inertia, buoyancy, and slamming as the unit penetrates the free surface. The wave force model is used to determine the rigid body motions of the units. Bulk forces on a matrix of units...
In 1996, Beach et al. first proposed the idea of mounting an echo-sounder on a Waverunner to measure nearshore beach profiles. This thesis discusses the Coastal Profiling System, an extension of the original work, which has been utilized to measure nearshore bathymetry at selected sites along the coasts of North...
A method is presented in this study for improving
empirical travel cost analyses when truncated data are
available. The analysis expands upon a Monte Carlo study
conducted by Riyadi (1993) which compared the coefficient
and consumer surplus estimates for five travel cost
estimators using both truncated and censored data. Riyadi...
Excessive growth by red clover, Trifolium pratense L., grown for seed
interferes with maximum seed production and harvest in Oregon's Willamette Valley.
This study was conducted during 1986 and 1987 on red clover cv. Kenland to
determine if plant height and dry matter production could be inhibited and seed yields...
