An evaluation of culverts on low volume forest roads in the Oregon Coast Range

Creator:: Piehl, Bradley T.
Abstract:: WRRI 106 is placeholder for the research findings of Project No. G-928-03 funded by U.S. Dept. of the Interior, Geological Survey. Findings are available in Piehl, Bradley T. (1986) An evaluation of culverts on low volume forest roads in the Oregon Coast Range (Masters Thesis, Oregon State University. Forest Engineering)...

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...

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...

Clay mineralogy in relation to landscape instability in the coast range of Oregon

Creator:: Istok, J. D.
Abstract:: The mineralogy of soils involved in mass movement in Oregon's coast range was examined to determine relationships between clay mineralogy and landscape instability. The objectives were: 1) to determine what kind of materials constitute the less than 2μ fraction of soils involved in different categories of mass movement, and 2)...

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...

Impacts of dredged material disposal on estuarine benthic macrofaunal communities in Coos Bay, Oregon

Creator:: Erman, Lisa T.
Abstract:: Hopper dredge disposal of coarse grained sediment was investigated between May and September, 1986, at a designated disposal area, Site G, in Coos Bay, Oregon. The objectives of the study were to: (a) identify and describe the benthic macrofaunal community structure at Site G during May and September, 1986; (b)...

Age, growth, and diet of fish in the Waldo Lake natural-cultural system

Creator:: Swets, Nicola L.
Abstract:: Waldo Lake, located in the Oregon Cascades, is considered to be one of the most dilute lakes in the world. Even with very low nutrient concentrations and sparse populations of zooplankton, introduced fish in the lake are large in size and in good condition when compared to fish from other...

Chromium (VI) sorption in soils : chemical behavior and solute transport modeling

Creator:: Schroth, Martin Herbert
Abstract:: Chromium spills on soils are causing severe groundwater contamination problems. To increase the performance of cleanup methods, the chemical behavior of chromium in soils and its transport through soils have to be understood. The objectives of this research were to investigate the sorption characteristics of chromium(VI) in soil and to...

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.)...
