PREFACE 



This report outlines a procedure for estimating the ultimate adjustment of 

 the shoreline and of the offshore bathymetry to changes in mean water level on 

 the Great Lakes. The procedure is based on a sediment balance model, cali- 

 brated and verified using profile changes measured on the eastern shore of 

 Lake Michigan over a 9-year period. The procedure is generalized for applica- 

 tion to other sections of the Great Lakes by considering regional variations 

 in storminess, and by requiring local evaluation of relevant geomorphic and 

 textural variables. 



The report was prepared by Edward B. Hands, under the supervision of 

 Dr. C.H. Everts, Chief, Engineering Geology Branch. Dr. W.L. Wood of Purdue 

 University and J. Pope of the U.S. Array Engineer District, Buffalo, provided 

 data used in the example problems. Appreciation is also extended to 

 W. Birkemeier, C.H. Everts, R.J. Hallermeier, R.D. Hobson, R. Jachowski, and 

 E. Meisburger for their review and suggestions which significantly improved 

 this report.
