FOREWORD 



This report consists of seven papers dealing with prediction of beach 

 change by means of numerical simulation models. The papers were recently 

 published by members of the Coastal Engineering Research Center (CERC) , 

 US Army Engineer Waterways Experiment Station (WES), and colleagues from other 

 organizations. The papers collectively provide an overview of the state of 

 research and engineering capabilities of numerical modeling of beach change, 

 as well as a framework for understanding the role of modeling in planning and 

 design of shore protection projects. This information is expected to be of 

 interest to US Army Corps of Engineers field offices and other public and 

 private organizations involved with technical aspects of beach change modeling 

 and the use of models in project planning and design. 



Each paper comprises a chapter of this report. Five of the papers 

 appear in the Proceedings of the Coastal Zone '89 conference, one is an 

 updated and expanded version of a paper appearing in that Proceedings, and one 

 appears in the Proceedings of the Beach Technology '88 conference. Coastal 

 Zone '89 was held under the auspices of the American Society of Civil 

 Engineers, and Beach Technology '88 was held under the auspices of the Florida 

 Shore and Beach Preservation Association. In support of the Coastal Zone '89 

 conference, the editor of this report organized a special session of five of 

 the papers included here under the session theme, "Shoreline Change and Storm- 

 Induced Beach Erosion Modeling," also used as the title of this report. 



Six of the papers were reformatted and minor corrections made in 

 phraseology for publication in this report. The reformatted versions can be 

 considered as reprints of the originals which appear in the conference 

 Proceedings, and the citation to the source is given at the top of the 

 respective title page. The paper by Mark B. Gravens is a substantially 

 revised version of his paper appearing in the Proceedings of Coastal Zone '89 

 and includes final results and conclusions not available at the time of 

 writing of the conference paper. Therefore, it is an original contribution. 



The papers treat three major topics; use of numerical simulation models 

 in project planning and design, prediction of long-term shoreline change, and 

 prediction of the response of the beach profile to storms. The first two
