46. The largest median change, -28.2 m^/m, resulted from the 



13 January 1964 storm. This storm also caused the largest range in volume 

 changes, from -69.2 ra^/m at profile line 8 to 6.6 m^/m at profile line 21 

 (the only line which accreted). 



47. Of the 10 storms, 3 were monitored by the Storm Erosion Study. 

 Though fewer profiles were surveyed during these storms, surveys were usually 

 conducted just prior to the storm and within 2 days after each event, 

 minimizing the effect of poststorm recovery. This is evident in the median 

 volume changes; median loss for these three storms was -22.3 m^/m compared 

 with the overall median loss of -9.7 m-^/m. Interestingly, the median 

 shoreline change was positive in two of the storms. Median slope change for 

 the three storms showed a flattening of the foreshore gradient by 0.015. 



Atlantic City, New Jersey 



48. Atlantic City is located on Absecon Island, a drumstick-shaped 

 barrier island (Figure 12) that is bordered by Great Egg Harbor Inlet to the 

 south and Absecon Inlet to the north. Lakes Bay separates the barrier from 

 the mainland. The study area includes the northern 5 km of the island which 

 is oriented N64 degrees E. Using wave data from a gage at Atlantic City, 

 Thompson (1977) reported an average wave height of 0.8 m with an 8-sec 

 period. This agrees well with the hindcast wave data in Table 1. 



49. Atlantic City has a wide, flat beach bordered on the west by a 

 boardwalk. According to McCann (1981), average annual shoreline movement is 

 -0.7 m. A number of beach-fill projects have been placed on the beach to 

 control erosion and they have affected the average shoreline movement 

 (Everts, DeWall, and Czerniak 1974). Many structures cross the beach 

 including piers, groins, and storm drains. 



50. Based on the 10 storms studied, Atlantic City experienced large 

 losses. Median poststorm erosion for this site was -11.3 m^/m. Profile line 

 1, located adjacent to and downdrift of the south jetty of Absecon Inlet, 

 experienced the largest and greatest range of changes. The median change at 

 profile line 1 was -30.1 m^/m varying from -150.8 m^/m on 6 November 1963 to 

 61.2 m-'/m on 17 December 1970. Both median shoreline and slope changes were 

 negligible for the storms considered.
