Solving engineering problems associated with coastal and offshore areas is one of the most important environmental challenges we face. The many natural resources in these regions require careful management based on sound scientific and technical information. Over 200 papers are included in this publication providing in depth state-of-the-art reviews, and current research and practices in coastal engineering. The five main divisions of coastal engineering presented here are: theoretical and observed wave characteristics; coastal processes and sediment transport; coastal structures and related problems; coastal, estuarine and environmental problems; and ship motions.
