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)...
The eruption of Mt. St. Helens provided the
opportunity to study secondary production of grazing insects in the context of disturbance. Two stream sites were chosen that significantly differed in how their
watersheds were impacted by the eruption. Clearwater Creek was catastrophically disturbed (physical alteration of habitat, loss of riparian...
Archival information about fish and water in the Umpqua Basin can be found in reports housed in disparate locations (e.g., offices of various State and Federal agencies and local organizations). A comprehensive bibliography of grey literature, important or uncataloged reports, and published reports is one means of recording what research...
Estuaries are once again emerging as important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. Yaquina Bay, located...
The Tualatin River Basin is located in the Washington County, Oregon. The river was detected having high chlorophyll a concentration and low dissolved oxygen concentration during summer time, which violated DEQ water quality standards. A mathematical model (HSPF) was used to simulate physical, chemical and biological processes in the basin...
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...
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...
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)...
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...
