At the request of the U.S. Army Engineer Division, Pacific Ocean (POD), a numerical model wave response study of proposed improvements to Maalaea smali boat harbor was conducted by the U.S. Army Engineer Waterways Experiment Station's (USAEWES) Coastal and Hydraulics Laboratory (CHL). The study was conducted as a revision and extension of previous studies (Lillycrop et al. 1993, Thompson and Hadley 1 994b) to assess the wave response of various alternative modification plans for the harbor. This report - is focused on the determination of an optimal design plan which would provide the harbor with adequate protection from the incident wave climate. Information provided in earlier reports is referenced in this report, but generally not repeated.

At the request of the U.S. Army Engineer Division, Pacific Ocean (POD), a numerical model wave response study of proposed improvements to Maalaea small boat harbor was conducted by the U.S. Army Engineer Waterways Experiment Station's (WES's) Coastal Engineering Research Center (CERC). The study was conducted to determine an optimal design plan of improvement which would provide the harbor with adequate protection from the incident wave climate. The existing harbor facility consists of an entrance channel, turning basin, two protective breakwaters, 93 berths, a haulout and launching ramp, and a 100,000-lb capacity cold storage plant. Following evaluation of the existing harbor, five proposed design plans of improvement were investigated.
