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...

Use of benthic sediments as indicators of marina flushing

Creator:: Noble, Scott Morgan
Abstract:: This report presents the findings of a sediment analysis program formulated to determine the flushing potential of various shaped small boat marina basins. Chemical tests regarding volatile solids, Kjeldahl nitrogen, grease and oil, and sulfides were performed with the results compared to established sediment quality criteria. These results were used...

Engineering Services of Submerged Aquatic Vegetation (SAV): Investigation of the Land-Building and Energy-Attenuating Properties of SAV Habitats Across Spatial Scales

Creator:: Holzenthal, Elizabeth R.
Abstract:: Submerged aquatic vegetation (SAV) species, such as seagrasses, are highly valued in estuaries because of the many economic, ecological, and cultural services that they provide, including shelter for fisheries, minimizing water turbidity, and improving am-bient water quality. SAV can also alter its physical environment by attenuating wave and current velocities,...

Pollution and tidal flushing predictions for Oregon's estuaries

Creator:: Choi, Byungho
Abstract:: The overriding goal of this study was to provide first order estimates of dilution and tidal flushing of waste discharges released hypothetically into various Oregon estuaries during critical low flows and tides. Causal relationships between discharged wastes and subsequent estuarine response were studied. Various approaches to determine the assimilative capacity...

Estuarine tidal hydraulics : one dimensional model and predictive algorithm

Creator:: Goodwin, Carl R.
Abstract:: A one-dimensional, implicit, finite-difference model is developed, calibrated and verified for three estuaries along the central Oregon coast. The model is used to generate controlled data for a large number of hypothetical estuaries. Two non-dimensional coefficients, K[subscript F], and. K[subscript I], are developed incorporating physical characteristics of the estuary which...

Coastal Soil and Structure Behavior during Earthquake-Tsunami Multi-Hazards

Creator:: Qiu, Yingqing
Abstract:: Coastal multi-hazards, i.e., earthquakes followed by tsunamis, induce severe damage to coastal infrastructure. The multi-hazards can cause soil liquefaction, which is one of the major concerns for evaluating sediments transport potential and structure failure mechanisms. The objectives for this work is threefold. First, to build and validate a soil numerical...

The effect of elevated pressure and high shear on oxygen uptake rates in activated sludge

Creator:: Streebin, Leale E.
Abstract:: The purification capacity of an activated sludge process is highly dependent of the rate of oxygen transfer from the air to the microorganisms. This rate can be increased in an air diffusion system by subjecting the culture to high shear and high pressure. A study of the effects of high...

Efficient Topobathymetric Mapping and 3D Spatial Analysis of Estuaries Using Multi-Platform, Multi-Temporal Data

Creator:: Lambert, Selina E.
Abstract:: Frequent 3D spatial mapping of estuaries is critical to understanding and modeling changes that can impact ecological health (e.g., water quality) and ecosystem services (e.g., aquaculture, nutrient cycling, and shoreline stabilization). However, obtaining accurate, repeat topobathymetric data for estuaries is a major challenge. Because shallow estuaries are typically not used...

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

Creator:: McKenzie, David Roller
Abstract:: During 1973 data was collected to analyze the seasonal variations of the tidal dynamics, water quality and sediments of the Alsea Estuary. A summary of historical information with a list of all known alterations to the estuary was made. A complete physical description, including the geographical setting and mixing classification...
