Coastal Wave Modeling
Coos Bay Inlet, located on the Pacific coast of southwestern Oregon, is protected by dual jetties constructed in 1928. Because the inlet is exposing to high energy environment, both north and south jetties have deteriorated since their construction. Aging, erosion of foundation, lack of maintenance, and frequent channel dredging in the past have accelerated the jetty deterioration. To ensure navigation safety, the U.S. Army Corps of Engineers is presently investigating the rehabilitation and redesign of jetties. This paper describes numerical storm wave modeling of the existing jetties to provide input forcing information to the physical model.
