PREFACE 



This report is pioblished to assist engineers in gaining a better 

 understanding o£ the basic concepts of lakeshore processes. The work 

 was carried out under the coastal construction research program o£ the 

 U.S. Panny Coastal Engineering Research Center. 



During the past several years, the trend of continued rise in monthly 

 average water levels of the Great Lakes has generated increased interest 

 by shoreline property owners into those processes which change the con- 

 figuration of the coastline and result, at times, in property loss. In 

 part, as a response to the increased interest by the general public, this 

 report was prepared by a Task Grovcp under the overall direction of Mr. 

 George M. Watts, Chief, Engineering Development Division. The Task Grotp 

 included: Dr. David B. Duane (Groip Leader), Dr. D. Lee Harris, Mr. 

 Richard 0. Bruno, and Mr. Edward B. Hands. 



It is hoped this report will provide the basis for a better under- 

 standing by the general public of the processes which affect the Great 

 Lakes shorelines. The literature cited and additional references in the 

 bibliography will direct the interested reader to more detailed and 

 technically conplex discussions on specific aspects of the concepts 

 presented in this report. 



Comments on this publication are invited.
