Each plan includes provisions for a new passenger vessel area on the west side of 

 the harbor and a new barge facility on the south side of Pier 2. Appropriate 

 dredging is incorporated into the plans to provide 35-ft depth for passenger ves- 

 sels and 25-ft depth for barges. Special features of each plan are: 



a. Plan 1 (Figure 3). Slip cut into coral stockpile to accommodate passenger 

 ships; fill south of Pier 2 to provide barge pier oriented nearly north/south 

 (referred to as Concept C in HDOT planning documents). 



b. Plan 2 (Figure 4). Slip cut into coral stockpile to accommodate passenger 

 ships; fill south of Pier 2 to provide barge pier parallel to Pier 2 (referred to 

 as Concept 12 in HDOT planning documents). 



c. Plans 3a, 3b, and 3c (Figure 5). Notch cut into coral stockpile to accom- 

 modate passenger ships; protective stub aligned with entrance channel 

 added to end of west breakwater in Plans 3b and 3c with length of 600 ft 

 (Plan 3b), and 1,000 ft (Plan 3c); fill south of Pier 2 to provide barge pier 

 parallel to Pier 2. 



d. Plans 4a, 4b, and 4c (Figure 6). Passenger ship pier located adjacent to 

 existing coral stockpile; protective stub added to end of west breakwater in 

 Plans 4b and 4c with length of 600 ft (Plan 4b), and 1,000 ft (Plan 4c); fill 

 south of Pier 2 to provide barge pier parallel to Pier 2. 



e. Plan 5 (Figure 7). 800-ft by 800-ft fill area added in southwest area of 

 harbor to accommodate passenger ships; fill south of Pier 2 to provide 

 barge pier parallel to Pier 2. 



/. Plan 6 (Figure 8). Identical to Plan 4b except 35-ft project depths dredged 

 to 38 ft 



g. Plan 7 (Figure 9). Combination of Plans 4b and 5 with 35-ft project depth 

 areas dredged to 38 ft and realignment of passenger ship pier along south- 

 east side of fill area. This plan represents a fully utilized harbor. 



Development of the numerical model and test procedures is described in 

 Chapter 4. 



Response of the existing harbor to waves was studied using field data and 

 numerical model results. Response of the alternative harbor plans was 

 investigated with only numerical model results. Harbor response to wind waves 

 and swell (short waves) is presented in Chapter 5. Harbor oscillation 

 characteristics (response to long waves) are presented in Chapter 6. For both 

 short and long waves, the harbor response is related to wave climate and to 

 relevant operational criteria at commercial piers. 



Conclusions and recommendations are given in Chapter 7. This chapter is 

 followed by references and appendices with detailed information supporting the 

 main report and notation definitions.
