Preface 



The research investigation described herein was conducted as part of the 

 Coastal Inlets Research Program (CIRP) under the work unit "Inlet Laboratory 

 Investigations." Overall program management for CIRP is directed by the 

 Hydraulic Design Section of Headquarters, U.S. Army Corps of Engineers 

 (HQUSACE). Program Monitors for tiie CIRP at HQUSACE are 

 Messrs. Barry W. Holliday, John Bianco, and Charles B. Chesnutt. The Program 

 Manager is Mr. E. Clark McNair, Coastal and Hydraulics Laboratory (CHL), 

 U.S. Army Engineer Waterways Experiment Station (WES), and CIRP Technical 

 Manager is Dr. Nicholas C. Kraus, CHL. 



The mission of the CIRP is to conduct applied research to improve USACE's 

 capability to manage federally maintained inlets which exist on all coasts of the 

 United States (including Atiantic, Gulf, Pacific, and the Great Lakes regions). 

 Objectives are to (a) make management of channels -design, maintenance, and 

 operation-more effective to reduce the cost of dredging, and (b) preserve the 

 adjacent beaches in a systems approach tiiat treats the inlet and beach together. 

 To achieve the above objectives, CIRP includes work units on short-wave 

 modeling, circulation modeling, channels and adjacent shorelines, inlet scour, 

 laboratory investigations, field investigations, and technology transfer. 



The study was conducted by CHL personnel, under the general direction of 

 Dr. James R. Houston, Director, and Mr. Charles C. Calhoun, Jr., Assistant 

 Director, CHL. Direct guidance was provided by Messrs. C. E. Chatiiam, 

 Chief, Navigation and Harbors Division, and Dennis Markle, Chief, Harbors and 

 Entrances Branch, CHL. Experiments were conducted by Messrs.William 

 Henderson, Computer Assistant, Cecil Dorrell, and Hugh F. Acuff, Jr., Civil 

 Engineering Technicians, under the direction of Mr. William C. Seabergh, 

 Principal Investigator, Dr. Jane M. Smith, and Messrs. Gordon S. Harkins and 

 Michael J. Briggs, all of CHL. Messrs. Wallace Guy and David Daily of the 

 WES Information Technology Laboratory provided instrumentation support. This 

 report was prepared by Dr. Smitii and Messrs. Seabergh, Harkins, and Briggs. 

 Word Processing and formatting were completed by Ms. Myra E. Willis, CHL.
