Beach Morphology Monitoring Program
Beach Profiles

This figure illustrates the contour change at profile PC068.  A contour change plot reveals the seasonal variability and a longer-term trend of the beach profile.  This example shows erosion in the winter and partial beach recovery in each of the two summer seasons.  By winter 2000, approximately 45- to 50- m (147- to 165-ft) of net erosion had occurred relative to the summer 1997 baseline position.  Both the 2.0-m (red line) and 3.0-m (blue line) contours are included because analyses have demonstrated that the shoreline position (average high water line, AHWL), as derived from topographic maps and aerial photographs, is typically between these two elevation contours.
