PREFACE 



This report is published to assist in the collection of reliable, 

 quantitative data on the behavior of shore erosion control structures 

 in the Great Lakes. Although these guidelines are oriented for use 

 in the Great Lakes, many features are applicable to any coastal zone. 

 The work in preparing these guidelines was carried out under the coastal 

 construction research program of the U.S. Army Coastal Engineering 

 Research Center (CERC) . 



This report was prepared by the staff of the Engineering Develop- 

 ment Division of CERC. Special acknowledgment is expressed to Messrs. 

 Dennis W. Berg and Adrian J. Combe III for their technical contributions 

 to these guidelines. The guidelines were reviewed in the early stage 

 of preparation by the U.S. Army Engineer Division, North Central, 

 Corps of Engineers; comments and suggestions from the Division Engineer, 

 North Central, were incorporated into the final report. 



The Coastal Engineering Research Center and its predecessor, the 

 Beach Erosion Board, have published numerous technical papers concerning 

 coastal engineering and the oceanographic forces which affect the coast.
