Figure A-1. Total shoreline and volume change by profile 

 line: October 1973 to December 1974. Vertical 

 datum equals 176.88 meters, IGLD. 



In terms of bluff erosion, three profile lines (1, 4, and 11) accreted 

 slightly though an amount less than 2.8 cubic meters per meter. This can be 

 seen in Figure 4. The average change was -9.3 cubic meters per meter with 

 profile lines 8 and 16 accounting for 44 percent of the total. Total volume 

 changes averaged -11.3 cubic meters per meter and were well correlated with 

 total shoreline movement (correlation coefficient of 0.93). 



Changes in these parameters with respect to time are shown in the plots in 

 Figure A-2 (profile lines 1 to 17). Because features such as shoreline posi- 

 tion could not be determined during the winter, changes for all the parameters 

 during January, February, and March have not been shown.
