PREFACE 



This report is published to provide coastal engineers with bluff 

 erosion data related to water level, storm occurrence, and bluff composi- 

 tion, useful for anticipating future effects from high water levels. 

 The report summarizes the results of a 3-year reconnaissance study of 

 bluff erosion, during high water levels, along a 250-mile segment of the 

 eastern shore of Lake Michigan. Selected data from the first 2 years of 

 this study were published in MP 10-75 by Davis, Fingleton, and Pritchett 

 (1975). The work was carried out under the coastal processes program 

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



Professor Richard A. Davis, Jr., Western Michigan University, 

 Kalamazoo, Michigan, was the principal investigator of the work done 

 under CERC Contract Nos. DACW72-70-C-0037 and DACW72-73-C-0003. The 

 report was prepared under the direction of Dr. C.J. Galvin, Jr., Chief, 

 Coastal Processes Branch, Research Division. Dr. Craig H. Everts, 

 Oceanographer, Coastal Processes Branch, was the CERC contract monitor.
