This study was undertaken to provide information needed in the design of ocean outfalls. A review of past investigations concerning forces on submerged objects is presented. Objects independent of any boundary and cylinders in boundary contact are considered. A solution for pressure distribution about a circular cylinder resting on a...
A laboratory investigation was undertaken to evaluate the effect
of lateral spacing and lateral diameter on the flow characteristics of
a three dimensional blowing manifold.
The model used in the experimental work was constructed of
clear cast acrylic pipe, five inches in diameter. Laterals of two and
four inch diameter,...
The effects of boundary geometry on internal density currents
in a density stratified reservoir were investigated in a laboratory
model. When water was simultaneously withdrawn and admitted to
the reservoir, a complex current regime was established. The general
flow pattern is described, and the influence of physical variables
on the...
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...
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...
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...
An interesting means of shoal removal has recently been implemented by the U.S. Army Corps of Engineers for use in shallow Pacific
Coast tidal inlets and estuaries. In the past, removal of shoaled material has consisted of physical excavation of material, transportation from the site, and placement in a spoils...
The system of partial differential equations which governs the
motion of a Newtonian fluid has been known for over a century. Yet,
due to the complexity of the equations, an analytical solution is known
only for a few simple geometries or a few special cases such as very
slow motion....
