Abstract:

The U.S. Army Engineer Division, Pacific Ocean, requested that the U.S. Army Engineer Waterways Experiment Station study the impact of proposed breakwater plans alternative plan2 and alternative plan 6 on flushing characteristics in the Maalaea Harbor, Maui. In order to accurately predict flushing time in a wind Iominant water hody such as Maalaea Harbor, a harbor-bay coupled system was developed and a trree-dimensional numerical model was invoked to conduct the study. The model was calibrated with 5 day prototype data collected during a July 27- August 3, 1993, field experiment, The report descrihes how different plans can affect the circulation pattern and, thus, the transport of the conservative tracer, inside and outside the harbor. Numerical model results show that the average flushing time is 2.9 days under existing harbor conditions, 3.3 days under alternative plan 2, 6.3 days under alternative plan 6, and 4.1 days under modified alternative plan 2.
