Preface 



This report presents 7 years of biweekly surveys of four profile lines which extend from the 

 dune seaward across the shoreface to a depth of 9 m. The data were collected with the 

 Coastal Research Amphibious Buggy, or CRAB, which permits high-accuracy surveys and 

 nearly all-weather capability. This is a unique data set, which now covers 11 years of 

 surveys. 



This study was authorized by the US Army Corps of Engineers (USAGE), Coastal 

 Engineering Area of Civil Works Research and Development. Work was performed under 

 the Field Research Facility Analysis (No. 32525) and the Field Research Facility 

 Measurements (No. 32524) Work Units, which are under the Coastal Flooding Research 

 Program at the Coastal Engineering Research Center (CERC) of the US Army Engineer 

 Waterways Experiment Station (WES). Technical monitors were Messrs. John H. Lockhart, 

 Jr., John G. Housley, David A. Roellig, and Barry W. Holliday. CERC Program Manager 

 was Ms. Carolyn Holmes. 



The report was prepared by Messrs. Guan-hong Lee and William A. Birkemeier under the 

 direct supervision of Mr. Thomas W. Richardson, Chief, Engineering Development Division. 

 General supervision was provided by Dr. James R. Houston and Mr. Charles C. Calhoun, 

 Jr., Director and Assistant Director, CERC, respectively. 



The data presented here were collected through the efforts of many individuals who were 

 personally committed to their collection. The hours were long, the work demanding, and the 

 rewards intangible. The drivers who kept the CRAB running and occasionally risked high 

 waves, steep beaches, and thunderstorms included Messrs. Mike Dominguez (1985-1986) and 

 Brian Scarborough (1986-1991) and occasionally Mr. Eugene Bichner. All of these 

 individuals also helped to keep the CRAB in operating order. When the CRAB tipped over in 

 October 1987, Mr. Bichner's and Mr. Scarborough's efforts led to a speedy recovery and 

 repair. 



A larger group of dedicated individuals operated the survey instruments, processed the 

 data, and spent countless hours on quality control and data management. That list includes 

 Messrs. Robert Battalio, Steve Blanchard, Matthew Cahur, Jonathan Lee, Michael Leffler, 

 Peter Howd, Mark McConathy, John Strider, and Mses. Wendy Smith, Debra Heibel, Juliana 

 Atmadja, and Rebecca Savage. Many others also spent time behind the survey instruments.
