Beach erosion is a chronic problem along open-ocean shores of the U.S. As coastal populations continue to grow and community infrastructures are threatened by erosion, there is increased demand for accurate info. regarding past and present trends and rates of shoreline movement, and a need for a comprehensive analysis of shoreline movement. This report on states bordering the Gulf of Mexico (Florida, Alabama, Mississippi, Louisiana, and Texas) summarizes the methods of analysis, interprets the results, provides explanations regarding the historical and present trends and rates of change, and describes how different coastal communities are responding to coastal erosion in 2004 (prior to Hurricanes Katrina and Rita).

The last decade has seen a remarkable increase in the application of geomorphology for numerous projects and investigations. Geomor phology is now viewed as an indispensable partner of engineering and geology in the world of applied science. For a discipline with few independent theories of its own, geomorphology has become a cosmopolitan science, drawing on many topics from allied sciences. To compile a list of successful and viable applications and contribu tions would be an arduous chore, if not an impossible task. Instead we have compiled a set of invited papers that represent some of the practical developments and uses of geomorphology over the past de cade. Such a compilation of papers will reflect our own back grounds, biases, associations, and personal and professional expe riences. We make no apologies for the topics omitted, but recognize that this volume could be prohibitively large if all the subdivisions of geomorphology were equally and fully covered. Our goal in assembling the papers for this volume was to empha size the concepts, principles, and applications of geomorphology. While techniques, procedures and practical applications are stressed, the reason for each investigation is as important as the method em ployed. This book, therefore, represents the methods used and reasons for applying geomorphology. Where case studies are used, they serve as examples that can be applied in related situations, similar settings and other locations. The authors have successfully addressed this goal in a broad selection of chapter topics.
The objective of this book is to focus on the physical processes that cause coastal erosion.Many scientists and engineers have focused their research on the entire range of physical processes from the waves and the currents in the nearshore to the response of the beach, via sand transport, resulting in a changing coastal morphology. Of these many processes, this book focuses only on those which directly relate the generation of coastal erosion. Some chapters deal exclusively with the physical processes, while others provide examples of erosion problems although most of the chapter topics have clear implications for issues of coastal-zone management, these issues are not belaboured as several other books are already available in this area. The objective is to provide state-of-the-art presentation of the science of coastal erosion processes.
