1929). All survey work for profile documentation was performed by the U.S. 

 Army Engineer District, Philadelphia. Profile line documentation is discussed 

 further in Appendix A. 



2. Frequency of Surveys. 



The general criteria considered in establishing survey frequencies were 

 the periods of maximum beach change caused by seasonal effects as well as 

 weather forecasts indicating a high probability of beach erosion due to 

 storms. Survey frequency was greatest during the fall and winter months with 

 a particularly large number of surveys taken during the first quarter of 1963, 

 at the beginning of the project, and in 1968-70 when a series of 10 weekly 

 surveys was done. Figures 20 and 21 show the number of surveys at Atlantic 

 City by quarter (3 months) and by month, respectively.
