PREFACE 



The investigation described in this report was authorized as a part of 

 the Civil Works Research and Development Program by the Office, Chief of En- 

 gineers (OCE), US Army. The work was performed under the work unit Numeri- 

 cal Modeling of Shoreline Response to Coastal Structures, which is part of 

 the Shore Protection and Restoration Program. Mr. J. H. Lockhart, Jr., and 

 Mr. John G. Housley were the OCE Technical Monitors. 



The study was conducted from 1 October 1984 through 30 April 1985 by 

 Dr. Nicholas C. Kraus, Research Physical Scientist, Coastal Engineering Re- 

 search Center (CERC), US Army Engineer Waterways Experiment Station (WES), in 

 conjunction with related engineering studies by Mr. Hans Hanson of the Univer- 

 sity of Lund, Sweden. This report presents the overall results of these ef- 

 forts. The CERC portion of the study was under the general supervision of 

 Dr. Robert W. Whalin, former Chief, and Dr. James R. Houston, present Chief, 

 CERC, and former Chief, Research Division, and Manager, Shore Protection and 

 Restoration Program; Mr. Charles C. Calhoun., Jr., Assistant Chief, CERC; Mr. H, 

 Lee Butler, Chief, Coastal Processes Branch; and Dr. S. Rao Vemulakonda, 

 Principal Investigator, Numerical Modeling of Shoreline Response work unit. 

 Ms. Joan Pope, Research Physical Scientist, Coastal Structures Evaluation 

 Branch of CERC, made a critical review of an early version of the manuscript. 

 Comments on this publication are invited. 



COL Allen F. Grum, USA, was Director of WES at the time of publication 

 of this report. Dr. Whalin was Technical Director.
