RD Flow's participation in the SUPERTANK project was part of a multi- 

 year effort to develop a portable system to study and monitor the long-term 

 fate of discharged dredged material. 



This effort was funded under the PLUMES project, sponsored by the U.S. 

 Army Engineer Waterways Experiment Station under the Dredging Research 

 Program. We would like to thank Dr. Nicholas C. Kraus for his strong 

 support of the program and for the opportunity to participate in the 

 SUPERTANK project. Ramon Cabrera of SonTek, Inc., prepared the plots in 

 Appendix H (contained in Volume II of this report).
