locality, Figure 17 provides a relative measure of how each site responds to 

 storms. The greatest variation between storms was recorded at Long Beach 

 Island, the longest locality. Misquamicut and Atlantic City, with the fewest 

 profile lines, showed the least variation. Jones Beach, with the lowest 

 median storm change, had considerable variation between storms.

Influence of Waves and Tides on Volume Changes 



65. An attempt was made to empirically relate median volume, 

 shoreline, and slope changes to the peak wave and water level parameters. 

 Figures 18 and 19 show two of the more interesting relationships which were 

 developed. Figure 18 plots the relationship between the peak water level and 

 the median volume change above NGVD. Though the data are scattered, they 

 display a slight linear trend (simple regression coefficient, r = -0.36). 

 The need for additional data, particularly during severe surge levels, is 

 readily apparent since these data only represent a small range of surge
