Asset Management Strategy for a Coastal Revetment Exposed to Increased Wave Forcing: Grays Harbor, Washington, U.S.A.

ABSTRACT
The Grays Harbor federal navigation project is on the southwest coast in Washington State, U.S.A. Recently, increased wave energy associated with the morphology of the harbor inlet throat has resulted in significant damages to the Point Chehalis revetment. Nearshore wave heights at the revetment have increased to the point where wave overtopping occurs routinely during a typical storm season (late October to late March). The high frequency of overtopping has resulted in progressive damage and subsidence of the structure over the past decade resulting in emergency repairs in 2010. This paper presents risk management tools utilized to help predict where future damages would occur as a result of the evolving nearshore wave conditions as well as a rehabilitation plan to mitigate future damages over the structures life cycle.
