APPENDIX I 

 SHORELINE AND CROSS-SECTION CHANGES 



Appendix I shows changes between successive surveys at the 18 profile 

 lines in this study. Column 1 is the date of the second of the two suc- 

 cessive surveys. Column 2 is the distance between positions of the MSL 

 shoreline on the profiles. Column 3 is the change in cross-sectional 

 area under the profiles. The area under the profiles is bounded on the 

 landward side by a vertical line passing through a point common to all 

 surveys of that profile line, on the bottom by the MSL datum, and on the 

 top and seaward sides by the surveyed profiles. Where profile lines 

 cross MSL more than once, the landwardmost intercept terminates the area. 

 Negative signs indicate erosion between surveys. 



Changes were computed at CERC using program PRCHAR. To obtain unit 

 volume loss in cubic yards per foot of shoreline, divide the figure in 

 column 3 by 27.
