Mapping the thermal climate of the H. J. Andrews Experimental Forest, Oregon

Creator:: Smith, Jonathan W.
Abstract:: The H. J. Andrews Experimental Forest in the Cascades of central Oregon provides a unique opportunity to study spatial climate patterns on a relatively small scale. Historical records at the 64 square-kilometer site provide a spatiallydense 30-year dataset. Thermal regimes at the H. J. Andrews are generally known but the...

Parents' social expectations as correlates of children's peer relations

Creator:: Pennington, Darren C.
Abstract:: Recent peer relations studies that have included parents as subjects have pointed to supporting behaviors performed by parents and their role in the development of children's peer relations. Findings from these studies have been similar to explanations of expectation effects. That is, expectation holders support their expectations by behaving in...

Precipitation-snowmelt timing and snowmelt augmentation of large peak flow events, western Cascades, Oregon

Creator:: Jennings, Keith S.
Abstract:: Despite advances in the understanding of rain-on-snow storms and their resulting peak flows, little is understood about the response of snowmelt to precipitation and the relative timing of the two at multiple temporal scales within such events. To address this issue, climate, snowmelt, and streamflow data were analyzed for 26...

Quantifying C and N contents and isotope signatures of SOM pools in the H. J. Andrews DIRT plots

Creator:: Keirstead, Heath
Abstract:: The mechanisms governing short- and long-term belowground carbon dynamics need to be understood. As part of a larger project developed to assess the effect of quantity and quality of litter inputs on the rate of soil organic matter (SOM) formation, I examined SOM in the H. J. Andrews Detritus Input...

Measurement and modeling the physical controls of snowmelt in the Pacific Northwest

Creator:: Mazurkiewicz, Adam B.
Abstract:: The physical controls of snowmelt in the Pacific Northwest (PNW) are poorly understood. While there have been numerous field and modeling investigations at the plot and watershed scale, few studies have identified how the snow energy balance (EB) components vary in importance both spatially and temporally. The identification of how...

Headwater stream macroinvertebrates of the H.J. Andrews Experimental Forest, Oregon

Creator:: Frady, Charles H.
Abstract:: Recent studies of headwater streams have demonstrated their importance to overall watershed biodiversity, nutrient cycling, and energy flux. However, little attention has been paid to long-term effects of forest harvest on macroinvertebrate communities in headwater streams. This study investigated headwater stream macroinvertebrate communities in the H.J. Andrews Experimental Forest, Oregon,...

Effects of Forest Harvest, Floods, and Wildfire on Bedload Export from Headwater Catchments in the H.J. Andrews Experimental Forest, 1957 – 2022

Creator:: Wright, Charles M.
Abstract:: This study examined how annual bedload export volume and bedload characteristics were related to disturbances including logging, floods, debris slides, and wildfires over 48 to 65-year periods in small, steep catchments in conifer forests of the western Cascade Range, Oregon. Bedload – the material rolling, sliding, or saltating along the...

Evidence of buried particulate organic carbon as foundation for heterotrophic carbon metabolism in the hyporheic zone of a montane headwater stream in the H. J. Andrews Experimental Forest, Oregon, USA

Creator:: Serchan, Satish P.
Abstract:: Streams and rivers play a critical role in global carbon (C) cycling by processing, storing, and transporting C. Headwater streams which make up more than 95% of the length of streams and rivers worldwide have disproportionate influence on fluvial C dynamics. The hyporheic zone (HZ) of headwater streams is a...

Capabilities of Detecting Medical Isotope Facilities through Radioxenon Sampling

Creator:: MacDougall, Matthew R.
Abstract:: Medical Isotopes are a necessity in modern medicine for cancer treatments and medical imaging. In order to ensure that the needs and demands are met for the medical procedures, facilities are put in place to produce these isotopes. There are over 25 different isotopes of interest being produced by more...

Proof of concept of the use of RAVEN and RELAP5-3D for risk informed safety margin characterization

Creator:: Riley, Thomas H.
Abstract:: This project was a proof of concept of the use of the RAVEN software, a tool developed for the Risk Informed Safety Margin Characterization (RISMC) approach, with RELAP5-3D. This novel approach combines older probabilistic and mechanistic approaches to look at how and why the complex systems of a nuclear power...
