PREFACE 



This report is published to provide coastal engineers with informa- 

 tion on rates of shoreline recession and on changes in these rates during 

 the most recent episode of high water levels on the Great Lakes. This 

 interim report is part of a study to develop and evaluate a profile re- 

 sponse model to explain the effects of rising water levels on shore 

 erosion. The work was carried out under the sediment hydraulic inter- 

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



This report was prepared by Edward B. Hands, under the general super- 

 vision of Dr. C.H. Everts, Chief, Engineering Geology Branch, Engineering 

 Development Division, CERC. 



Assistance of the following individuals and organizations is grate- 

 fully acknowledged: the staff at Hears State Park who were extremely 

 helpful during various data collection periods; P. Wood who assisted in 

 the recovery of survey markers and generously provided transportation in 

 the Silver Lake Dune area; the Tide and Water Level Branch, National 

 Oceanic and Atmospheric Administration (NOAA) , Rockville, Maryland, for 

 providing lake level data; the Permit Branch, U.S. Army Engineer District, 

 Detroit (NCE) , for help in procuring aerial photography; the field office 

 in Grand Haven, Michigan, for surveying bench marks in 1976; the 30th 

 Engineering Battalion, Fort Belvoir, Virginia, for the 1976 profile 

 survey; the National Ocean Survey (NOS) , NOAA, for 1971 and 1975 profile 

 surveys; and the Great Lakes Environmental Research Laboratory, NOAA 

 (formerly the U.S. Lake Survey) for initiating shore-normal profiling 

 in 1967 and 1969 at most of the sites used in this study. 



The author appreciates the manuscript review and the helpful comments 

 by Dr. C.H. Everts, Dr. C.H. Carter, and the U.S. Army Engineer Division, 

 North Central .
