Sediment production and delivery in Pistol River, Oregon and its effects on pool morphology

Creator:: Russell, Periann
Abstract:: Sediment production and delivery in Pacific Northwest coastal streams can have damaging effects on channel morphology and anadromous fish habitat. The research in Pistol River was designed to determine if a link exists between sediment delivery processes and degradation of fish habitat. Objectives of this basin-wide analysis were to: 1)...

Particle selection for tube building and the stabilization of sediments by Leptochelia dubia (Crustacea, Tanaidacea): interactions with bacteria and microalgae

Creator:: Krasnow, Lynne D.
Resource Type:: Dissertation

Longshore grain sorting and beach-placer formation adjacent to the Columbia River

Creator:: Li, Zhenlin
Abstract:: The formation of beach placers primarily involves processes of waves and currents that selectively sort and concentrate the valuable minerals according to their densities, sizes and shapes. Black sand placers are found on the beaches adjacent to the mouth of the Columbia River. Reviews of historical shoreline changes show that...

Along-coast variations of Oregon beach-sand compositions produced by the mixing of sediments from multiple sources under a transgressing sea

Creator:: Clemens, Karen E.
Abstract:: Heavy mineral compositions of sands from Oregon beaches, rivers and sea cliffs have been determined in order to examine the causes of marked along-coast variations in the beach-sand mineralogy. The study area extends southward from the Columbia River to the Coquille River in southern Oregon. The heavy-mineral compositions were determined...

Sediment characteristics and the trophic status of four Oregon lakes : project completion report

Creator:: Davis, Gerald E. and Larson, Gary L.
Abstract:: This study was undertaken to evaluate the usefulness of sediment records for correlating changes in the sediment characteristics of four Oregon lakes with past cultural developments of the lakes and their watersheds. The lakes chosen for this study were Waldo, Odell, and Diamond lakes located in the Cascade mountains and...

An assessment of a Stream Reach Inventory and Channel Stability Evaluation : predicting and detecting flood-induced change in channel stability

Creator:: Morét, Stephanie L.
Abstract:: Pre-flood (1995), and post-flood (1996) channel stability surveys were conducted on 22 reaches along Oak Creek, Benton County, Oregon in an effort to note if the flood of February 1996 altered the channel and if the channel stability survey that was being used accurately predicted the channels resistance to change...

Analysis of benthic infauna communities and sedimentation patterns of a proposed fill site and nearby regions in the Columbia River Estuary

Creator:: Higley, Duane L., Holton, Robert L., Komar, Paul D., 1939-, and McMechan, Karla J.
Abstract:: The Port of Astoria has proposed to fill a 32.4 hectare inter- and subtidal area at the mouth of Youngs Bay, Columbia River, Oregon. The possible effects of this fill on the biota and sedimentation patterns of this area were studied from 31 August 1975 to 29 February 1976. Part...

Investigation of the hydraulic, physical, and chemical buffering capacity of Missoula Flood Deposits for water quality and supply in the Willamette Valley of Oregon

Creator:: Iverson, Justin
Abstract:: The Willamette Silt is a surficial geologic unit composed of successive Missoula Flood Deposits that underlies 3100 km2 (1200 mil) of arable land in the Willamette Valley of Oregon. The Willamette Silt protects the underlying regionally important Willamette Aquifer from agricultural contamination while acting as a semi-confining unit and a...
