Figure 9. Time changes in positions of various contours intersecting the 

 beach face. Distance of selected contours from their final 

 position was determined in the October 1976 survey. Positive 

 ordinate values indicate net recession between the indicated 

 year and the final (1976) survey; negative values indicate net 

 progradation for the indicated period.
