up to 0.75 m of erosion occurred along the shoreline and foreshore with depo- 

 sition on the nearshore bar. 



115. Post-Hurricane Josephine bathymetry of 16 October exhibited major 

 changes from the September survey (Figure 46) . Up to 1 m of erosion occurred 

 in an area 200 m either side of the landward end of the pier, extending be- 

 tween 50 and 250 m from the baseline. Areas of similar erosion, produced by 

 the extensive nearshore bar development, occurred at the north and south ends 

 of the survey region, with as much as 1 m of accretion occurring about 250 m 

 from the baseline. The scour hole at the seaward end of the pier deepened 

 about 0.25 m because of the high waves. 



116. The final survey of the year was completed on 27 November. High 

 waves experienced at the FRF on a number of occasions prior to the survey 

 caused the trough to elongate to the south near 350 m from the baseline. A 

 rip channel developed to the south of the pier as evident from the bending of 

 the 3- to 5-m contours at 300 m from the pier. An unusual shore-parallel bar 

 and trough system was also measured at the 2-m depth. 



Photography 



117. Two sets of photographic data were used to document nearshore and 

 beach conditions in the vicinity of the FRF during 1984. Daily 35-mm trans- 

 parencies were taken of the beach from the pier looking both north and south 

 (Figure 47) . Quarterly aerial photographic missions were also flown as indi- 

 cated in Table 11, usually at a scale of 1:12,000. Figure 48 is a sample of 

 the imagery obtained (3 October 1984) .
