Wave Response of Kaumalapau Harbor, Lanai, Hawaii
Abstract
Kaumalapau Harbor, the main commercial harbor for Lanai, Hawaii, is being studied for development. This harbor is protected from the open ocean by a single nibble-mound breakwater. The U.S. Army Engineer Waterways Experiment Station (WES) was asked to carry out a wave response study for the harbor. WES collected field data to validate physical and numerical models and assess hindcast data. A numerical model study was used to assist in optimizing the placement of field wave gauges, to maximize efficiency of physical model experiments by identifying the most promising modification plans and most damaging incident wave directions, and to evaluate harbor oscillation characteristics of the proposed plan. An undistorted, three-dimensional physical model of Kaumalapau Harbor was used to evaluate harbor response to short-period waves for existing conditions and two alternative harbor layout configurations, straight and dogleg breakwater plans, respectively, for three incident wave directions as well as optimize the stability of the proposed breakwater design.
