The role of bedrock groundwater in rainfall-runoff response at hillslope and catchment scales

Creator:: Gabrielli, Christopher P.
Abstract:: Bedrock groundwater dynamics in headwater catchments are poorly understood and poorly characterized. Direct hydrometric measurements have been limited due to the logistical challenges associated with drilling through hard rock in steep, remote and often roadless terrain. Here we develop and use an inexpensive, portable bedrock drilling system to explore bedrock...

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...

Trickle-down ecohydrology : complexity of rainfall interception and net precipitation under forest canopies

Creator:: Allen, Scott T.
Abstract:: Rainfall interception is a primary control over the moisture input to a forested ecosystem through the partitioning of precipitation into throughfall, stemflow, and an evaporated component (i.e. the interception loss). Rainfall interception is a spatially and temporally varying process at multiple scales, but heterogeneity in interception processes are poorly understood...

Elucidating Key Aspects of the Biology of Select Species of Snail-killing Flies (Diptera: Sciomyzidae) in Oregon

Creator:: Alzahrani, Fares
Abstract:: Members of the family Sciomyzidae, known as snail-killing or marsh flies, are unique amongst insects in that the vast majority of reared species feed exclusively on mollusks and as a result their biological control potential has been well documented in the scientific literature. However, in North America there is a...

The Effect of Sill Height on Decay in Air-Seasoning Crossties

Creator:: Rogers, Leon R.
Abstract:: The sustainable use of wood for rail ties requires chemical treatment to increase service life and maintain structural integrity. Treatment can only be applied after lengthy air-seasoning to reduce moisture content in wood, but seasoning leaves ties exposed to attack by decay fungi for up to a year. One factor...

Potential for Using Boron Compounds with Differing Water Solubilities in Pastes for Remedial Treatment of Utility Poles

Creator:: Uysal, Selim
Abstract:: Boron and boron compounds have been long used for pressure treatment, dip-diffusion, and remedial treatments of wood because of their proven efficacy against fungi and insects. These materials are especially attractive because their high water solubility promotes deeper penetration into wood. Other useful properties of boron include its neutral pH,...

Development of a test method for assessing water repellency and derived physical stability of preservative systems for railroad ties

Creator:: Beck, H. Greeley
Abstract:: Resistance to moisture uptake is an important attribute of some wood preservatives and can help reduce moisture cycling that leads to the development of deep checks. While the potential for preservative treatments to help improve wood/moisture interactions is acknowledged, there are no tests that specifically evaluate this performance parameter. Checking...

Effects of best management practices on copper migration from Douglas-fir lumber treated with ACZA, CA or ACQ

Creator:: Ye, Min
Abstract:: Copper is the most common ingredient in waterborne preservatives and provides excellent activity against most fungi and insects. However, issues associated with copper migration from treated wood have created increasing concerns about potential risks to non-target organisms in surrounding environments, especially those in sensitive aquatic environments. Various Best Management Practices...

Establishment of Kura clover for seed with wheat intercrops

Creator:: Snelling, John P.
Abstract:: Kura clover (Trifolium ambiguum M. Bieb.) is slow to establish and has low seed yields the year after establishment. Intercropping a cereal grain during clover seed field establishment could provide additional revenue to seed growers, provided that intercropping did not jeopardize future clover seed yields. Factorial combinations of spring- and...
