The aim of this review series is to present critical commentaries on knowledge in the field of coastal and ocean engineering. Each article will review and illuminate the development of the scientific understanding of a specific engineering topic. Critical reviews on engineering designs and practices in different countries will also be included. The first volume of the review series is a collection of five papers reviewing a wide range of research topics in coastal engineering.The first paper, written by Yeh, discusses one of the fundamental issues concerning many fluid flow problems, namely, free surface boundary conditions. In the second paper, a survey on another boundary dynamics, the seafloor dynamics is presented. Foda reviews recent studies on the nonlinear wave energy transfer into the seabed and different modes of wave-induced sediment fluidization processes in cohesive as well as in noncohesive seabeds. Several issues concerning the interactions between sediment deposit and marine structures, such as pipeline and breakwater, are also briefly reviewed. One of the active research areas in modeling wave propagation is the construction of a unified model which is valid from deep water to shallow water. Liu discusses several existing models. The sediment movement in the surf zone is a complex system. It can usually be decomposed into the longshore and the cross-shore components. Dean focused his discussion on the cross-shore sediment transport process. In the last paper, van der Meer presents a comprehensive review of the design consideration for a rubble mound breakwater. Both hydraulic and structural responses are discussed. Design formulas and graphs are presented, which can be used for a conceptual design of rubble mount breakwater.

Since September 1992, there has been an unprecedented number of major tsunami events. Chronologically, the ten sites were: Nicaragua, in September 1992; Flores, Indonesia, in December 1992; Okushiri, Japan, in July 1993; East Java, Indonesia, in June 1994; Shikotan, Russia, in October 1994; Mindoro, Philippines, in November 1994; Skagway, Alaska, in November 1994; East Timor, Indonesia, in May 1995; Irian Jaya, Indonesia, in February 1996; Chimbote, Peru, in February 1996. These tsunamis caused substantial damage and many casualties. Now is the time to review this extraordinary phenomenon so as to prepare for forthcoming tsunami events.The purpose of this book is to review and update our knowledge of long-wave runups and our recent experience in field surveys of tsunami runups. Comparisons of numerical, analytical, and physical prediction models are made using existing laboratory and field data. Also presented are state-of-the-art tsunami prediction models and detailed discussions on tsunami runup phenomena.

This invaluable volume consists of five articles covering a wide range of topics in coastal oceanographic engineering. The reader can find an article discussing the modern bubble measurement techniques applied to field studies of bubble dynamics in coastal shallow water. A comprehensive review paper on nonlinear modulation of water waves provides readers with a new perspective on nonlinear processes in the coastal and ocean wave environment. For those who are interested in wave modeling, there are two review articles discussing various wave models, which can be used to study wave-structure interactions and harbor oscillations. Finally, readers who are interested in the subject of stratified flows can find an article presenting the detailed laboratory observations of lock-exchange flows.
