ARMY ENGINEER DISTRICT PORTLAND OR
Pagination or Media Count:
Under the Monitoring Completed Coastal Projects Program, an assessment of the performance of a training jetty extension at Umpqua River, Oregon, was conducted. The monitoring was performed over the period from May 1983 through May 1984. It included the collection and analyzing of current, salinity, tide, wave, and beach and channel data. Evaluation of these data is discussed in detail. Comparison of the prototype data with that of a physical hydraulic model of the Umpqua River entrance conducted in 1970 was also performed to determine its predictive capabilities. Data on the performance of the project and observations made in the prototype, as well as conclusions and recommendations based on the monitoring effort, are reported herein.
