Typical wave patterns for representative waves from 227, 182, and 137 deg are 

 shown in Photos 1-9 for Plan 19. 



Current patterns and magnitudes obtained for Plan 19 are presented in Plates 66- 

 80 for representative waves from 227, 182, and 137 deg. For waves from all wave 

 directions, currents along the shoreline between the new breakwater and the existing 

 entrance moved to the west, and then seaward adjacent to the east side of the 

 structure; and currents west of the causeway moved seaward along the structure. 

 For waves from 227 and 182 deg, currents east of the existing entrance moved in an 

 easterly direction, while they moved to the west for waves from 137 deg. Currents 

 entered the harbor through the breach in the causeway for waves from 227 and
