PREFACE 



The US Army Engineer District, Norfolk (NAO) , requested the US Army 

 Engineer Waterways Experiment Station's (WES's) Coastal Engineering Research 

 Center (CERC) to assist in the design of a Beach Erosion Control and Hurricane 

 Protection Project for Virginia Beach, Virginia. The study was divided into 

 two major parts consisting of a seawall design and a beach nourishment design. 

 This report is the second in a three-report series and addresses the physical 

 model seawall overtopping evaluation. Funding authorizations by NAO were 

 granted in accordance with Intra-Army Order No. AD-86-3018. 



This study was conducted at CERC under general direction of Dr. J. R. 

 Houston, Chief, and Mr. C. C. Calhoun, Jr., Assistant Chief, CERC; and under 

 direct supervision of Mr. T. W. Richardson, Chief, Engineering Development 

 Division (CD); Mr. C. E. Chatham, Chief, Wave Dynamics Division (CW) ; 

 Ms. J. Pope, Chief, Coastal Structures and Evaluation Branch, CD; and 

 Mr. D. D. Davidson, Chief, Wave Research Branch, CW. This report was prepared 

 by Mr. W. J. Lillycrop, Ms. J. Pope, and Dr. C. E. Abel and edited by 

 Ms. S. A. J. Hanshaw, Information Technology Laboratory, WES. 



During this study close coordination was maintained through 

 Mr. D. Pezza, NAO Project Manager, and Ms. J. Pope, CERC Project Manager. 

 Acknowledgment is made to all others involved at NAO for their assistance in 

 the study. 



The authors extend special acknowledgment to Dr. Charles E. Abel, our 

 friend, colleague, and co-author, who produced all hurricane and extratropical 

 wave simulations and provided valuable guidance and insight. Dr. Abel passed 

 away on 19 April 1987. 



Commander and Director of WES during the investigation, preparation, and 

 publication of this report was COL Dwayne G. Lee, EN. Technical Director was 

 Dr. Robert W. Whalin.
