ABSTRACT: The U.S. Army Engineer Division, Pacific Ocean (CEPOD), requested that the U.S. Army Engineer Waterways Experiment Station numerically study the wave response of proposed improvement plans to the small boat harbor at Maalaea, Maui, Hawaii. This study is an update of earlier studies to assess the wave response of the existing harbor and seven proposed modification plans. Deepwater wave data used in earlier studies were derived from measurements obtained in the Monitoring of Completed Coastal Projects Program. The deepwater wave climate used for the current study was taken from a National Data Buoy Center buoy located southwest of the island of Lanai. The availability of deepwater data nearer the vicinity of Maalaea Harbor, combined with improved harbor modeling technology, significantly improves the validity of overall results. The results of this study show that all of the proposed harbor plans showed some degree of improvement over the existing plan in providing protection from incident wind waves and swell to berthing areas. However, Plans 2, 6, and 6a are potentially more hazardous to navigation during high wave conditions due to a constricted harbor entrance exposed to wind waves and swell.
