PREFACE 



The US Army Engineer Division, New England (NED) requested the US Army 

 Engineer Waterways Experiment Station (WES) Coastal Engineering Research 

 Center (CERC) to conduct numerical and physical model studies to determine the 

 frequency of flood levels at Roughans Point and at other coastal areas in 

 Revere, Saugus, and Lynn, Massachusetts. The studies were conducted prin- 

 cipally to provide greater confidence in the flood protection plan for 

 Roughans Point as presented in the planning report (NED 1983) and were part 

 of a larger study, "Continuing Planning and Engineering Studies for Roughans 

 Point," provided for under the 12 September 1969 Southeastern New England 

 authorization of the US Senate Committee on Public Works. A small funding 

 contribution came from Revere Backshore planning studies conducted under the 

 same authority. 



This report contains the results of the numerical investigations con- 

 ducted between May 1984 and December 1985. Close consultation and coopera- 

 tion were maintained between CERC and NED throughout the study, and the 

 efforts of Mr. Charles Wener, NED, were particularly important in its suc- 

 cessful completion. 



Work was performed by personnel of the Research Division (CR), CERC, 

 under the direction of Dr. James R. Houston, former Chief, CR. Mr. Thomas A. 

 Hardy, Coastal Processes Branch (CR-P), was the Principal Investigator for 

 this study under the direction of Mr. H. Lee Butler, former Chief, CR-P, and 

 current Chief, CR. Mr. Hardy was responsible for the probability modeling, 

 storm surge modeling, flood routing, and synthesis of the total modeling ef- 

 fort. Mr. Peter L. Crawford, Coastal Oceanography Branch (CR-O), was respon- 

 sible for the wave modeling. Mr. Crawford worked under the direction of 

 Dr. E. F. Thompson, Chief, CR-O. Upon completion of the study, Chief and 

 Assistant Chief, CERC, were Dr. Houston and Mr. Charles C. Calhoun, Jr., 

 respectively. This report was edited by Ms. Shirley A. J. Hanshaw, In- 

 formation Products Division, Information Technology Laboratory, WES. 



COL Allen F. Grum, USA, was the previous Director of WES. COL Dwayne G. 

 Lee, CE, is the present Commander and Director. Dr. Robert W. Whalin is 

 Technical Director.
