Figure 62. Cumulative land area changes (above MSL) at Corson Inlet, 1949-74, 



recreational pote-itial of the beach was not decreased, but there was a loss of 

 valuable coastal property landward of the beach. Fixed manmade structures such 

 as roads, parking lots, and buildings were also jeopardized. 



2. Alongshore Sand Movement . 



a. Longshore Transport Analysis . The following analysis utilizes wave 

 height data (averaged by month) and a constant wave period obtained from a gage 

 in Atlantic City (Fig. 15), and wave direction data from visual observations 

 near Sea Isle City (Fig. 17). These data were applied in an analysis using 

 the energy flux method (U.S. Army, Corps of Engineers, Coastal Engineering 

 Research Center, 1977). 



Wave power, P, reaching the beach (see Fig. 8) was obtained using the
