Soil engineering properties and vegetative characteristics for headwall slope stability analysis in the Oregon coast range

Creator:: Bransom, Mark
Abstract:: Six headwalls in the central Oregon coast range were selected for study of soil engineering properties and vegetativecharacteristics important for analysis of slope stability. The headwalls were considered representative of those which would be candidates for timber leave areas due to geomorphic and topographic features, including steepness of slope and...

The wild and scenic river act : problems of implementation in Oregon

Creator:: Root, Ann L.
Abstract:: In 1968, Congress passed the Wild and Scenic River Act creating a system of rivers protected from dams and other development. By 1987, segments of four Oregon rivers were protected by the Wild and Scenic River System: the Rogue, Illinois, Owyhee, and a portion of the Snake along the Idaho...

Quantifying the fertilizer value of algal meal : an evaluation of an integrated dairy-anaerobic digester-algae production facility

Creator:: Andrews, Shannon B.
Abstract:: Algae have shown great potential as a source for renewable fuels. However, current production schemes have not been able to prove a sustainable energy return on investment due in part to the high costs of nutrient addition and the energy required for drying the biomass. Integrated algae-dairy production systems have...

Composition, structure, and biomass of cottonwood-dominated gallery forests along a successional gradient, Willamette River, Oregon

Creator:: Fierke, Melissa K.
Abstract:: Recognizing the importance of native black cottonwood-dominated riparian forests is especially important to preserve, protect, and manage for biodiversity in the Willamette River Valley. Species composition, structure, and biomass along a successional gradient from stand initiation to late succession of black cottonwood (Populus balsamfera L. subsp. trichocarpa (T. & G.)...

Water chemistry of Oregon Cascade wilderness lakes : a comparison to 1985 data

Creator:: Logan, Michael Burke
Abstract:: The Western Lake Survey (WLS) of 1985 documented the status of lake water chemistry across the western US and inferred population representations of various subregions and geomorphic units via statistically analyses. Results from this 1985 study indicated that lakes of the Oregon Cascades had the second most pristine and dilute...

Ecological land units of Bear Creek watershed and their relationship to water quality

Creator:: Mattison, Jeffrey L. and Buckhouse, John C.
Abstract:: During 1975 and 1976 a sedimentation study was conducted in the Bear Creek watershed, located in the southeastern corner of central Oregon's Crook County. A Rocky Mountain infiltrometer was used to simulate high intensity rainfall over 468 sedimentation plots. Rainfall and runoff were measured and a sample of the runoff...

Assessing the Repeatability of the Oregon Freshwater Wetland Assessment Methodology

Creator:: Heigh, Lisa F.
Abstract:: This paper presents the results of field tests of the Oregon Freshwater Wetland Assessment Methodology. It begins with a review of the history of wetland assessment techniques, including an in-depth review of some more popular methods. State and federal wetlands legislation are briefly discussed and the utility of regional wetland...

Elevation, thermal environment, and stream temperatures on headwater streams in northeastern Oregon

Creator:: Meays, Cynthia L.
Abstract:: A case study examining the relationship between stream temperatures and the thermal environment through which streams flow was conducted on the headwaters of 4 tributaries of the Burnt River (Barney, Elk, Greenhorn, and Stevens Creeks) in northeastern Oregon during July through August 1998 and 1999. Barney Creek and Stevens Creek...

Placement of felled western juniper trees over a stream channel : Effects on water temperature, streamside willow shrubs, and redband trout

Creator:: Matney, Casey A.
Abstract:: All streams in Oregon that are inhabited by salmon and trout have a statemandated water temperature standard. However, temperatures of many streams, especially during summer months, exceed the seven-day average maximum temperature parameter (200 C for redband trout inhabited streams) accepted by the Oregon Department of Environmental Quality. To date,...
