Available in PDF, EPUB and Kindle. Book excerpt: In a letter from the Portland District dated 28 March 1975, subject: 'Tidal Hydraulics Committee Services - Umpqua River Entrance, Oregon, ' the Committee on Tidal Hydraulics was requested to assist in the evaluation of navigation problems at the entrance to the Umpqua River. As a result, the 80th meeting of the committee was held in Portland on 20-21 May 1965, primarily to discuss and consider these problems. The history of the project, existing conditions, and maintenance problems were described to the Committee. The report describes the meeting presentations and conclusions.

Book excerpt: The Umpqua River estuary model was of the fixed-bed type, constructed to scales of 1:30 horizontally and 1:100 vertically, and reproduced the lower 28 miles of the Umpqua River and an adjoining portion of the Pacific Ocean. The model was equipped with the necessary appurtenances for accurate reproduction and measurement of tides, tidal currents, waves, salinity intrusion, freshwater inflow, shoaling distribution, and other significant prototype phenomena. The purpose of the model study was to determine the optimum plan for the reduction of shoaling and elimination of crosscurrents in the navigation channel at the entrance. Model verification tests indicated that the model hydraulic and salinity regimens were in satisfactory agreement with those of the prototype for comparable conditions. It therefore can be assumed that the model provided quantitative answers concerning the effects of the proposed plans on the hydraulic and salinity regimens of the estuary. The optimum plan consisted of existing conditions plus a 2600-ft extension of the training jetty to the outer end of the south jetty. Results of model tests indicate that the optimum plan eliminated the crosscurrents without aggravating the wave climate or shoaling conditions. (Author).
