pier, and extended 100 m north and 150 m south of the pier. In addition, the 

 trough under the pier enlarged about 25 m to the south along the seaward 200 m 

 of the pier. 



114. Two surveys were performed in September: one survey the first 

 week and one pre-Tropical Storm Dean survey on the I8th (this was only a 

 partial survey and is not presented in Appendix C). Both indicated very minor 

 changes since the August survey. 



115. Following Tropical Storm Dean (Part IV), a survey was completed on 

 1 October. Several deep areas of erosion occurred under and near the pier as 

 well as along much of the -1.0 to -2.0 m contours. Accretion occurred in 

 areas located 200 to 300 m north and south of the pier, generally between the 

 -2.0 and -4.0 m contours. The large shoal south of the pier (300 ra) also 

 accreted up to 0.5 m. Figure 45 shows the prestorm and poststorm bathymetry 

 changes as contours of accretion and erosion. 



116. The last survey of the year was completed on 21 November. This 

 survey showed as much as 0.75 ra of erosion along the near shore bar (100 to 

 200 m) and the seaward face of the offshore bar (400 to 500 m) . Deposition of 

 up to 1 m of sediment occurred in the trough under the pier and between the 

 bars from 200 to 400 m. 



Photography 



117. Two sets of photographic data were used during 1983 to document 

 nearshore and beach conditions in the vicinity of the FRF. Daily 35mm trans- 

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

 south (Figure 46). Approximately every 4 months, aerial photographic missions 

 were also flown on the flight lines and dates indicated in Table 12, usually 

 at a scale of 1:12,000. Figure 47 is a sample of the imagery obtained on 



3 October 1983.
