Evaluation of estuarine channel conditions in Coos Bay, Oregon using side-scan sonar

Creator:: Hartman, Gregory L.
Abstract:: Side-scan sonar records in Oregon's Coos Bay estuary navigation channels were obtained at intervals of two to three months during the November 1974 - October 1975 time period from Coos Bay Channel Mile 11+50 to 15+20, and from a reach in the Marshfield Channel. A limited side-scan survey effort was...

Behavior of stream inflows to a stratifying field reservoir

Creator:: Chasse, James Peter
Abstract:: The behavior of a stream upon entering a field reservoir was studied at various stages of stratification. The principal field techniques included fluorometric and temperature surveys. General relationships were obtained, between dimensional and locational characteristics of the inflow current and the thermal structure of the impoundment. As predicted by analytical...

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...

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...

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...

Flows associated with harbor ship traffic

Creator:: Downs, Richard Allen
Abstract:: The purpose of this study was to ascertain the potential erosion impacts associated with ship movements in confined waters. The flow associated with a ship passage can be separated accordingly: (1) the propeller wake, (2) flow about the hull, and (3) associated waves. Each of these areas has been analyzed...

Seasonal variations in tidal dynamics, water quality, and sediments in the Coos Bay estuary

Seasonal variations [in] tidal dynamics, water quality, and sediments in the Siletz Estuary

Creator:: Rauw, Charles Irving
Abstract:: The Siletz Estuary was studied in 1973 to determine seasonal variations in tidal dynamics, water quality, and sediments. Tidal ranges and times were measured and compared to predicted values at two positions within the bay. Tidal ranges and times were analyzed to determine the dampening and phasing conditions within the...
