Figure 3-9. Beach profile change at FDEP Monuments R-7 and R-8. 



Calculation results at R-43 for the three selected storms, with the final profile position as 

 post-TS Gordon, are shown in Figure 3-10. The storms caused moderate beach erosion and 

 recession of the dune face, with the Thanksgiving Day northeaster of November 1984 producing 



30 



the most erosion. In comparison with the beach recession calculated at R-7 for Applegate 



The SBEACH calculation for R-43 advanced the MHWL approximately 17 ft. Material contributing to advance the MHW 

 shoreline was taken from the dune and upper beach.
