PREFACE 



This report presents a method for estimating long-term erosion 

 rates resulting from a rise in sea level, based on Bruun's (1962) method 

 with an exponential curve fitted to the offshore beach profile, The 

 method is approximate and is intended to supplement conventional analyses 

 of historical profile and shoreline changes rather than to supplant such 

 analyses. The work was carried out under the coastal engineering research 

 program of the U.S. Army Coastal Engineering Research Center (CERC) . 



The report was prepared by J. Richard Weggel, Chief, Evaluation Branch, 

 under the general supervision of N.E. Parker - , Chief, Engineering Develop- 

 ment Division.
