begun on the construction of a large recreational resort on the spit
in the early 1900's. At the outset, the resort appeared to have a
promising future. However, a three-year delay...
Theoretical b:::-eaking 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...
The Port of Astoria has proposed to fill a 32.4 hectare inter- and
subtidal area at the mouth of Youngs Bay, Columbia River, Oregon. The
possible effects of this fill on the biota and sedimentation patterns
of this area were studied from 31 August 1975 to 29 February 1976. Part...
Documented and forecasted trends in rising sea levels and changes in storminess patterns have the potential to increase the frequency, magnitude, and spatial extent of coastal change hazards. To develop realistic adaptation strategies, coastal planners need information about coastal change hazards that recognizes the dynamic temporal and spatial scales of...
