Along much of the shoreline of the world, tidal inlets play an important role in nearshore processes, providing links between the coastal oceans and protected embayments. Their study is of particular importance not only for the understanding of fundamental processes in coastal oceanography but also for engineering and the proper management of the delicate equilibrium of our shorelines. This volume, based on the International Symposium on Hydrodynamics and Sediment Dynamics of Tidal Inlets held at Woods Hole, MA, presents the reader with an overview of contemporary research on these important features. The coverage includes: - mathematical modelling, including a review of inlet hydrodynamics, - observations on hydrodynamics, - sedimentology and morphology, - tidal deltas, - processes and policies pertaining to sedimentation, and the - impacts of shore protection and dredging in beaches.

Changes in sea level caused by global warming can be disastrous to modern civilization. Therefore, it is important to use accurate and reliable methods to monitor any change. During this century, and, in particular, the last three decades, tide-gauge records have been used to show these changes related to the world's oceans. Aubrey and Emery suggest, however, that tidal gauges should not be used unquestioningly as a benchmark for measuring eustatic sea-level changes. Tectonism, subsidence, ocean current variability, and human activity can, and do, affect the accuracy of these records. Understanding the reasons for changes in land and sea levels is essential for the proper development of coastal regions. The results of this study provide guiding data for scientific, engineering, and policy solutions to coastal flooding. Determining the true causes of relative subsidence, and how to use geological and oceanological controls, will allow us to exist within our natural environment, rather than force nature to conform to our legal and temporary 'remedies.'
