Closure depth is central to many coastal engineering and coastal management activities. This quantity represents an estimate of the average annual depth limit to which sediment motion is active to a significant degree. Thus, this depth provides an approximate limit to which nourished beach profiles will equilibrate and a limit, shallower than which, sediment will tend to be active in the vicinity of a borrow pit. Since the equilibrated dry beach width is inversely related to the closure depth, this quantity is significant to beach nourishment design and performance. Additionally, closure depth provides an obvious inshore limit for the siting of borrow pits since if the sediment transport activity is significant in the vicinity of the borrow pit, some of the sand placed in the nourishment project will be "short circuited" back into the borrow pit and thus lost to the nourishment project. This report provides the results of a reexamination of the closure depths along the Florida shoreline based on the most recent wave hindcasts, compares these results with estimates developed more than a decade ago and presents recommendations for future engineering and management applications.

At the coast all is not what it seems. Decades of beachfront development have seen a variety of efforts to stabilize the shoreline to protect ill-placed beachfront property, both from shoreline erosion and from storm damage. Both of these problems become increasingly critical in a time of rising sea level. Many natural beaches are backed by sea walls, while others have been transformed by whole series of groynes, offshore breakwaters and a plethora of other schemes. Many recreational beaches are actually artificial replicas of the real thing, emplaced to protect badly placed infrastructure and maintained only through ongoing costly beach nourishment. However, all of these attempts to stabilize the shoreline are far from benign. Degradation and even complete loss of the all important recreational beach sometimes results from seawall emplacement. Increasingly, the choice of shoreline stabilization approach will depend upon plans for future response to rising seas which in many cases may involve retreat from the shoreline rather than holding the line. This book explores, through a series of case studies from around the globe, the pitfalls of shoreline stabilization and provides a ready reference for those with an interest in shoreline management. It is particularly timely in a time of global change.

This book is written for engineers, students of coastal processes and laypersons interested in beach nourishment, which consists of the placement of large quantities of good quality sediment on the beach to advance the shoreline seaward. The improvement of project performance through proper design and the predictability of performance are emphasized. The overall longevity of a project is addressed as are local erosional areas. The roles which wave height, project length and sediment quality play in project performance are addressed quantitatively. The results are illustrated through reference to a number of monitored nourishment projects. Biological and economic aspects of beach nourishment are addressed.
