Multiple linear regression was used to develop equations for 12-,
24-, and 36-hour surface wind forecasts for the wind energy site at
Goodnoe Hills. Equations were derived separately for warm and cool
seasons. The potential predictors included LFM II model output, MOS
surface wind forecasts extrapolated from surrounding stations, pressure...
A method of calculating surface evapotranspiration by separately
including the effects of vegetation and atmospheric evaporative demand
under the condition of nonlimiting soil moisture is presented. A
literature survey is conducted to determine the effects of plants on
evapotranspiration.
To represent the atmospheric evaporative demand, the original
potential evaporation equation...
This thesis is based on the excavations of the Robert Newell farmstead (35MA41), excavated in 2002 and 2003 by the Oregon State University Department of Anthropology archaeological field school. Robert Newell lived at this farm from 1843- 1854. Major architectural features, including a brick hearth and postholes were discovered at...
This thesis will explore the architectural material culture excavated at the Robert Newell Homestead (35MA41), currently located in Champoeg, Oregon. Specifically, the research focuses on the vernacular architecture or the features and construction methods used that both reflect the environment and the cultural traditions of the dwellings occupants. The Robert...
Current bioassessment efforts are focused on small wadeable streams, at least partly because assessing ecological conditions in non-wadeable large rivers poses many additional challenges. In this study, we sampled 20 sites in each of seven large rivers in the Pacific Northwest, USA, to characterize variation of benthic diatom assemblages among...
The number of sites sampled must be considered when determining the effort necessary for adequately assessing taxa richness in an ecosystem for bioassessment purposes; however, there have been few studies concerning the number of sites necessary for bioassessment of large rivers. We evaluated the effect of sample size (i.e., number...
Evaporation was studied along the Middle Fork of the John Day River in northeastern Oregon. Evaporation pans and various meteorological sensors recorded data at nine sites during the summer of 1998; measurements were made at each site over a 3-4 day period. A Dalton-type evaporation model was produced using water...
