Two-dimensional fields of total water depth, breaker index, wave angle, wave 

 height, and wave number (more precisely, the wave phase gradient) are printed 

 for a portion of the grid extending from rows 1=1 to 1=50 and from columns 

 J=11 to J=41. Figure 11 shows the extent of this region relative to the en- 

 tire grid system. 



Example II: Homer Spit, Alaska 



102. Bathymetry for this application (see Figure 12) is digitized 

 onto a grid with 96 rows in the offshore (x) direction and 83 cells in the 

 longshore (y) direction. Cell dimensions are approximately 417 ft in the 

 x-direction and 833 ft in the y-direction (about 10 times the resolution used 

 in the Duck, North Carolina, examples. One wave condition is considered in
