Nawiliwili Breakwater Stability Study Nawiliwili Harbor, Kauai, Hawaii. Hydraulic Model Investigation.

Abstract : A hydraulic model investigation was conducted at geometrically undistorted, linear scales of 1:31 and 1:25, model to prototype, to evaluate the stability against wave attack of three areas of the existing breakwater at Nawiliwili Harbor, Kauai, Hawaii. Where the existing crown and/or harbor-side slope proved to be unstable, additional tests were conducted to check the stability of the rehabilitation designs proposed by the Pacific Ocean Division. All existing and proposed rehabilitation designs were tested for the worst breaking wave conditions that could be produced for the selected wave periods, water depths, and bathymetry seaward of the test sections.
