PREFACE 



This report provides coastal engineers with data on suspended- sediment 

 concentration collected in and near the surf zones at Ventnor, New Jersey, 

 and Nags Head, North Carolina. These data are of interest because a sig- 

 nificant amount of sand eroded from beaches is transported in suspension 

 through the surf zone. The work was carried out under the coastal processes 

 program of the U.S. Army Coastal Engineering Research Center (CERC) , 



This report is based on a manuscript prepared by Mr. John C. Fairchild, 

 Research Hydraulic Engineer, retired from the CERC Research Division. The 

 manuscript was condensed for publication by Dr. Cyril J. Galvin, Jr., Chief, 

 Coastal Processes Branch, under the general supervision of R.P. Savage, 

 Chief, Research Division, CERC. 



The author acknowledges the officials of the City of Ventnor, New 

 Jersey, including Mr. Kiger, City Engineer, who gave permission to collect 

 data from the Ventnor City Pier, and G. Vavrek, Ventnor piermaster, for 

 his personal assistance during data collection in 1965 and 1971. Data 

 collection was made at Jennette's Pier, Nags Head, North Carolina, by per- 

 mission of W. Jennette, and the Louisiana State University Coastal Studies 

 Institute who was there under contract with the Office of Naval Research. 



The assistance of the many CERC contributors is also acknowledged, 

 particularly F.F. Monroe who performed the initial analysis of the Nags 

 Head data; C.R. Schweppe and D.C. Fresch, student trainees, who prepared 

 numerous scatter plots and performed other helpful tasks; L.E. Meyer le and 

 M.G. Essick who were helpful in reducing and compiling the data; and B. Sims 

 and M. Fleming who wrote programs for computer -generated plots of the field 

 data.
