Effectiveness of Spur Jetties at Siuslaw River, Oregon. Report 1, Prototype Monitoring Study
In 1985, the rubble-mound jetties at the entrance to the Suislaw River, Florence, OR, were extended offshore. In addition, on the ocean side of each jetty, one long spur oriented 45 deg to the main structure was constructed shoreward of the seaward end of each of the twin jetties. The spur system was investigated as a cost-reducing alternative to significant linear jetty length extension which would reduce sediment shoaling and dredging requirements in the channel and improve navigability. Cost reductions were expected in reduced maintenance dredging and in actual construction and material cost. Data collected during field monitoring of the area are related to incident wave conditions. Spur-induced current patterns and sediment deposition patterns, along with annual dredging records are analyzed to evaluate structure performance.
