PREFACE 



This report is published to provide coastal engineers with reliable 

 profile and sediment data collected during a 2-year study of beach 

 changes along a 250-mile segment of the eastern shore of Lake Michigan.

 U.S. Army Coastal Engineering Research Center (CERC) .

 DACW72-70-C-0037 with Western Michigan University (WMU) , Kalamazoo, 

 Michigan. Professor R.A. Davis, while at WMU was the principal investi- 

 gator, assisted by WMU graduate students, particularly W. George
