Late winter 1992 sampling for water quality in three stream segments of the Tualatin River Basin, Oregon

Creator:: Miner, J. Ronald, Nelson, Peter O., Vedanayagam, Samuel, Oregon State University. Water Resources Research Institute, and Oregon State University. Extension Service
Abstract:: The Tualatin River Basin in Washington County, Oregon has been identified by the Oregon Department of Environmental Quality (DEQ) as "Water Quality Limited." Algal blooms have become commonplace in the lower , reaches of. the river during summer months. Phosphorus has been identified as the nutrient upon which to base...

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...

Modeling the Tualatin River system including Scoggins Creek and Hagg Lake: model description, geometry, and forcing data

Creator:: Wells, Scott A., Berger, Christopher, Knutson, Mike, and Oregon State University. Water Resources Research Institute
Abstract:: The goal of this phase of the study was to develop a model of the Tualatin River incorporating Scoggins Creek and Hagg Lake. This tool will be used in conjunction with a hydrologic model, the EPA HSPF model (Johnson, Imhoff, and Kittle, 1984), to analyze management strategies to improve water...

Seasonal variations in tidal dynamics, water quality and sediments in the Siuslaw Estuary

Creator:: Utt, Michael Ernest
Abstract:: Seasonal data on tides, water quality and sediments in the Siuslaw Estuary were collected. Tide and velocity data were analyzed to evaluate damping conditions in the estuary. The system was found to approximate a weakly damped standing wave. A strong relationship of damping conditions to river flow was observed. The...

Chetco River tidal hydrodynamics and associated marina flushing

Creator:: Tang, Shing Shirly
Abstract:: The purpose of this study was to provide an understanding of the interrelationships between fresh and salt water Circulation, tidal transport and flushing patterns in the Chetco River estuary and its boat basins. Field work and water quality measurements were conducted at the entrance of the Chetco River during 1975...

Effects of pressure and deposit thickness on the stabilization rate of benthic marine sludge deposits

Creator:: Muellenhoff, W. P.
Abstract:: The biochemical degradation of domestic sludge deposits exposed to benthic marine conditions was investigated using a laboratory Deep Sea Simulator. The rate and extent of deposit stabilization were determined for select hydrostatic pressures and hydrogen acceptor conditions by monitoring depletion of particulate organic carbon in 2.0 and 3.0 centimeter deposits....

Airphoto analysis of estuarine circulation

Creator:: Weise, Harry Gordon
Abstract:: Aerial photography has become a valuable method of acquiring information on estuarine current circulation patterns. The method provides a comprehensive picture of nearly simultaneous surface water movements. It represents a significant improvement over conventional surface float and current meter methods because large areas may be covered in great detail with...
