Each of the post-storm profiles was lacking a survey point 
at the seawall. It is not known whether or not the berm 
eroded back to the seawall (although photographs seem to indi- 
cate that erosion did extend to the seawall). Since the total 
volume of eroded material is somewhat dependent on that mea- 
surement, a comparison of volumes will not be made. Verifica- 
tion is made by comparing the computed change in elevation at 
specific distances from the seawall with the measured changes 
at those locations as shown by the post-storm survey and 
reported in the storm report. 
148. The beach erosion numerical model with seawall modification was 
used to simulate the storm event for the three profiles described above. 
Input data for the berm geometry were taken from the surveys, whereas storm 
data were extracted from the storm report. Results of those simulations are 
shown in Table 8 and discussed in paragraph 151. 
149. Simulation for Sea Bright. To demonstrate that berm recession in 
the project area could be adequately predicted by the model, a simulation of 
beach erosion was performed for the November 1953 storm that made landfall in
