Shoreline changes due to jetty construction on the Oregon Coast

Creator:: Lizarraga Arciniega, Jose Roman
Abstract:: Patterns of beach erosion and accretion due to jetty construction are examined for the coast of Oregon. All jetty systems are included with the exception of those on the Columbia River, making a total of nine systems. All evidence indicates that these areas of the Oregon coast are experiencing a...

The Erosion of Siletz Spit, Oregon

Creator:: Rea, Campbell Cary
Abstract:: Siletz Bay is a drowned river valley filled with Holocene alluvial and estuarine sediments and is separated from the ocean by a sand spit 3.8 km in length. Since the area was settled by white man in the 1890's, the bay has apparently experienced rapid siltation, due to increased farming...

Breaking waves : a review of theory and measurements

Creator:: Gaughan, Michael Kenneth
Abstract:: Theoretical breaking criteria for progressive surface gravity waves are examined, and laboratory and field experiments concerned with breaking waves are reviewed with respect to the testing of these breaking criteria. The measurements of Komar and Simmons are presented here for the first time. Only three theoretical breaking criteria have been...

Beach profile changes and onshore-offshore sand transport on the Oregon coast

Creator:: Aguilar Tunon, Nicolas A.
Abstract:: Two beaches with significant differences in grain size and thus in beach profile morphology and response to wave conditions were studied on the Oregon coast. Gleneden Beach, just south of Siletz Spit and Lincoln City, has a median grain size of 0.36 mm (medium sand) and a steep beach face...

Sediment transport beneath an undular hydraulic jump

Creator:: Broome, Robert
Abstract:: Field observations are made of the formation of backwash ripples on the beachface, formed by undular hydraulic jumps generated by backwash down the beach face colliding with wave bores. Measured ripple wavelengths range from set averages of 48 to 70 cm. Within a particular set of ripples there is a...

Along-coast variations of Oregon beach-sand compositions produced by the mixing of sediments from multiple sources under a transgressing sea

Creator:: Clemens, Karen E.
Abstract:: Heavy mineral compositions of sands from Oregon beaches, rivers and sea cliffs have been determined in order to examine the causes of marked along-coast variations in the beach-sand mineralogy. The study area extends southward from the Columbia River to the Coquille River in southern Oregon. The heavy-mineral compositions were determined...

The spring 1976 erosion of Siletz Spit, Oregon, with an analysis of the causative wave and tide conditions

Creator:: McKinney, Barbara Ann
Abstract:: During the period 1970-76, Siletz Spit on the mid-Oregon coast has suffered foredune erosion. This erosion is associated with high wave conditions along the coast, produced by intense storms in the North Pacific. During the winter of 1972-73 and during January through March 1976 the erosion was particularly severe. The...
