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 of tidal estuaries
were described and applied to ten of Oregon's estuaries for
which limited hydraulic flow information was available.
This study mainly focused on the well-mixed condition
common to most of Oregon's estuaries. The characteristics
of the estuary used in the calculations were: tidal
volumes, river flow, topography, and salinity information.
Comparison of results from the modified tidal prism
method and fraction of freshwater method for determining
tidal flushing was made.
Stommel's and Thomann's one-dimensional model was used
to predict the spatial pollutant distribution from a waste
outfall discharging into an estuary. Flushing rates in an
overmixed estuary were determined using Gibson's method as
well as flushing times calculation for a marina-like small
basin. / Graduation date: 1976
