PREFACE 



The work described in this report was conducted by Aeronautical Research 

 Associates of Princeton, Inc., Princeton, New Jersey, for the U. S. Army 

 Engineer Waterways Experiment Station (WES), under Contract No. DACW39-80-C- 

 0087. 



This report describes the development of a three-dimensional, finite- 

 difference hydrodynamic model and comparison of the model results with field 

 data. It also reports on the development towards a comprehensive sediment 

 dispersion model; a laboratory study on the gravitational settling, entrain- 

 ment, and deposition of cohesive sediments; and example calculations of sedi- 

 ment dispersion in the Mississippi Sound. 



Dr. Y. Peter Sheng served as the Principal Investigator of this study 

 and prepared this report. The author wishes to thank Mr. H. Lee Butler, WES, 

 for his helpful suggestions and assistance during the course of this work. Drs, 

 Peter L. McCall and J. Berton Fisher, Case Western Reserve University, assisted 

 in the laboratory experiments on sediment. Drs. Richard Schmalz, Jr., and 

 Robert Jensen of the Hydraulics Laboratory (HL), WES, assisted in providing 

 the Mississippi Sound hydrodynamic data and wave data, respectively. 



The contract was monitored by Mr. H. Lee Butler. Through 30 June 1983, 

 Mr. Butler was a Research Physicist in the Wave Dynamics Division (WDD), HL, 

 WES, under the general supervision of Mr. H. B. Simmons, Chief, HL, and Dr. 

 R. W. Whalin and Mr. C. E. Chatham, Jr., former and acting Chiefs, WDD. 

 The WDD and its personnel were transferred to the Coastal Engineering Research 

 Center of the Waterways Experiment Station on 1 July 1983 under the super- 

 vision of Dr. R. W. Whalin. 



Support for the research came from various sources: the U. S. Army 

 Engineer District, Mobile; the Coastal Flooding and Storm Protection Program, 

 Mr. J. H. Lockhart, Jr., Technical Monitor, Office, Chief of Engineers; and 

 the Field Verification Program (FVP). Funds for publication were provided 

 by CERC.
