be relatively larger; and as one moves away from this region (for example, 

 closer to the lateral and offshore boundaries) the cells appear to be rela- 

 tively smaller than they really are. In what follows, for convenience, the 

 results will be shown on the uniform grid.

direction and 73 cells long in the onshore/offshore direction. The figure 

 shows Amelia and Cumberland Islands, the navigation channel, the locations of 

 the two jetties on St. Marys Inlet (the jetties are stair-stepped for the CUR- 

 RENT model) , and bathymetric contours with elevations referenced to msl (mlw 

 plus 3 ft) . The offshore boundary of the grid is at an approximate depth of 

 63 ft msl. Note the shoals offshore, south of the south jetty, and north of 

 the north jetty. For convenience, these will be referred to hereafter as the 

 offshore, south, and north shoals, respectively.
