PREFACE 



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

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

 Center (CERC) to conduct physical model studies to determine overtopping rates 

 and wave-induced pressures on a seawall proposed for construction at Virginia 

 Beach, Virginia. This is the first of three reports that describe tasks con- 

 ducted in support of the Virginia Beach, Virginia, Beach Erosion Control and 

 Hurricane Protection Project. Funding authorizations by CENAO were granted in 

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



Physical model tests were conducted at CERC under general direction of 

 Dr. James R. Houston, Chief, CERC; Mr. Charles C. Calhoun, Jr., Assistant 

 Chief, CERC; Mr. C. Eugene Chatham, Chief, Wave Dynamics Division; and 

 Mr. D. Donald Davidson, Wave Research Branch (CW-R) . Tests were conducted by 

 Messrs. Cornelius Lewis, Sr., Engineering Technician, John M. Hegglns, Com- 

 puter Technician, and Lonnie L. Friar, Electronics Technician, under the 

 supervision of Ms. Martha S. Heimbaugh, Civil Engineer, and Mr. P. J. Grace, 

 Hydraulic Engineer, CW-R. Mr. Kenneth W. Hassenflug, Computer Specialist, 

 CW-R, was responsible for software development throughout execution of the 

 pressure tests and during subsequent data analysis efforts. This report was 

 prepared by Ms. Heimbaugh and Messrs. Grace, Davidson, and John P. Ahrens, 

 Oceanographer, CW-R. Report editing was performed by Ms. Shirley A. J. 

 Hanshaw, Information Products Division, Information Technology Laboratory, 

 CEWES. 



Throughout the course of this study liaison was maintained with 

 Ms. Joan Pope, CERC's overall Project Manager, and CENAO representatives: 

 Messrs. David Pezza, Project Manager, Owen Reece, Hydraulic Engineer, and 

 Steve Geuslk, Structural Engineer. The contributions of these individuals, 

 and all other Involved CENAO personnel, are acknowledged with thanks for their 

 assistance in the investigation. 



Commander and Director of CEWES during the investigation and the prepa- 

 ration and publication of this report was COL Dwayne G. Lee, CE. Technical
