Preface 



The study described herein was conducted by the U. S. Army Engineer 

 Waterways Experiment Station (WES) Coastal and Hydraulics Laboratory 

 (CHL). The CHL was formed in October 1996 with the merger of the WES 

 Coastal Engineering Research Center and Hydraulics Laboratory. Dr. James 

 R. Houston is the Director of the CHL and Messrs. Richard A. Sager and 

 Charles C. Calhoun, Jr., are Assistant Directors. 



The study was performed under Work Unit 22113 "Mouth of the Colorado 

 River, Texas" in the Monitoring Completed Coastal Projects Program which 

 was renamed in October 1996 as the Monitoring Completed Navigation 

 Projects (MCNP) Program. The MCNP Program Manager during the study 

 was Ms. Carolyn Hohnes. Technical Monitors of the MCNP Program at 

 Headquarters, U.S. Army Corps of Engineers were Messrs. John H. Lockhart, 

 Barry W. Holliday, and Charles B. Chesnutt. 



Dr. Thomas E. White was Principal Investigator (PI) during the data 

 collection and much of the data analysis portion of this program. Dr. David B. 

 King, Jr., was PI for a portion of the data analysis and the report preparation 

 phase of the program. Ms. Terri L. Prickett co-authored and coordinated final 

 report preparation. During the course of this study, Drs. White and King, and 

 Ms. Prickett were supervised by Mr. William L. Preslan, Chief, Prototype 

 Measurement and Analysis Branch (PMAB), and Mr. Thomas W. Richardson, 

 Chief, Coastal Sediments and Engineering Division, CHL. 



Other CHL personnel made substantial contributions to the program. The 

 data collection systems were designed by Messrs. Ralph E. Ankeny, William 

 E. Grogg, Gary L. Howell, and James Rosati III of PMAB. Field team 

 members included Messrs. Larry G. Caviness, William M. Kucharski, Douglas 

 C. Lee, Charles J. Mayers, Jeff Sewell, and Mses. Debra Shafer and Rhonda 

 M. Lofton of PMAB, and Messrs. Michael W. Leffler and C. Ray Townsend 

 of the Field Research Facility at Duck, NC. Data analysis was performed by 

 Ms. Rhonda M. Lofton, Mr. James P. McKinney, and Dr. Joon P. Rhee of 

 PMAB. Additional research was performed by Dr. Reginald A. Beach, 

 College of Atmospheric Sciences, Oregon State University under Contract 

 DACW39-90-K-0009, and by Mr. Guoxiong Liang, Scripps Institution of 

 Oceanography (SIO), University of California, San Diego under the 

 supervision of Dr. Richard J. Seymour, SIO, under Contract DACW39-90- 

 K-0007. Other data measurements, principally impoundment basin surveys, 

 were supplied by the U.S. Army Engineer District, Galveston.
