PREFACE 



This report Is published to provide engineers and scientists with guide- 

 lines on the use of salt marsh vegetation as a shore erosion control measure 

 in coastal regions of the United States. 



This is one of a series of reports to be published to form a Coastal Engi- 

 neering Manual (CEM). The report is based, in part, upon information present- 

 ed in SR-4 "Building Salt Marshes Along the Coasts of the Continental Iftiited 

 States" (Woodhouse, 1979). The work was carried out under the U.S. Army 

 Coastal Engineering Research Center's (CERC) Development of Functional and 

 Structural Design Criteria work unit, Coastal Structure Evaluation and Design 

 Program, Coastal Engineering Area of Civil Works Research and Development. 



The report was prepared by P.L. Knutson, Ecologist, Coastal Ecology 

 Branch, CERC, and W.W. Woodhouse, Jr., Professor Emeritus of Soil Science, 

 North Carolina State University, under the general supervision of E.J. Pullen, 

 Chief, Coastal Ecology Branch, and Mr. R.P. Savage, Chief, Research Division, 

 CERC. R.A. Jachowski, former Chief, Coastal Design Criteria Branch, Engineer- 

 ing Development Division, was the CEM project monitor. 



The authors express appreciation to S.W. Broome and E.D. Seneca for their 

 review and comments. 



Technical Director of CERC was Er. Robert W. Whalin, P.E.
