Wave Climate and Wave Response, Kawaihae Deep Draft Harbor, Island of Hawaii, Hawaii
Present and projected commercial activities in Kawaihae Deep Draft Harbor, Island of Hawaii, HI, indicate that a deeper basin and entrance channel and better protected berthing areas will be needed. The U.S. Army Engineer District, Honolulu, in coordination with the Harbors Division, Department of Transportation, State of Hawaii, requested numerical (computer) model studies in support of harbor planning. Wave climate incident to Kawaihae Deep Draft Harbor was developed from National Data Buoy Center directional buoy data. Numerical model STWAVE was used to modify the buoy data to account for significant differences in exposure between Kawaihae and the buoy locations. Numerical model CGWAVE, validated with field measurements for short waves (wind waves and swell), was used to: (1) evaluate the impact of deepening the existing harbor, which was found to be minimal; (2) determine optimum length for a proposed stub extending seaward parallel to the existing entrance channel from the tip of the existing breakwater; and (3) evaluate the technical feasibility of six alternative modifications to the harbor. Model results were compared to experience in the existing harbor and to general criteria for operational acceptability.
