Advances In Coastal Structure Design

These conference proceedings present authoritative papers on new experience and research, particularly that which has led to advances in design procedures. It covers design, construction and performance experience of coastal structures and breakwaters particularly including new developments.

Coastal structures are an important component in any coastal protection scheme. They directly control wave and storm surge action or to stabilize a beach which provides protection to the coast.This book provides the most up-to-date technical advances on the design and construction of coastal structures and sea defenses.Written by renowned practicing coastal engineers, this edited volume focuses on the latest technology applied in planning, design and construction, effective engineering methodology, unique projects and problems, design and construction challenges, and other lesions learned.Many books have been written about the theoretical treatment of coastal and ocean structures. Much less has been written about the practical practice aspect of ocean structures and sea defenses. This comprehensive book fills the gap. It is an essential source of reference for professionals and researchers in the areas of coastal, ocean, civil, and geotechnical engineering.

Advances in Coastal Structure Design presents a compendium of 10 papers addressing the state-of-the-art advances in Coastal Structure Design by internationally renowned authors. The papers focus on the tools and techniques used to analyze coastal processes and design engineering solutions to them. The first three chapters present multiple view points and policies regarding how the coastal-structure debate in the United States came to be and how policies are evolving to handle issues concerning the interactions of structures with shorelines. Including a paper on the global perspective surrounding the policy, design, construction and monitoring of coastal structures and the third demonstrating how a good knowledge of multi-disciplinary areas of geotechnical, geologic, and seismic conditions are essential to successful planning and design of coastal structures. The following chapter discusses a key aspect of coastal structure design, which is modeling. The remaining papers present insightful information on: wave distributions and probabilities; an overview of breakwater design and construction since the 18th century; and advances in structural design aspects on performance-based design. The final chapter demonstrates how sand, vegetation, cobbles, and small structures can be effectively utilized to provide coastal protection. CONTENTS INCLUDE: Coastal Structure Debate: Public and Policy Aspects; International Perspectives on Coastal Structure Uses; Geotechnical Consideration for Coastal Structure Design; Numerical Modeling as a Design Tool for Coastal Structures; Physical Modeling Considerations for Coastal Structures; Selection of a Design Wave Height for Coastal Engineering; Historical Overview of Rubble Mound Structure Design and Construction; Advances in Breakwater and Revetment Design; Design Aspects of Groins and Jetties; Application of Coastal Engineering in Coastal Zone Management.

Advances in Coastal Hydraulics contains twelve papers that report on recent developments in several areas of coastal hydraulics. The papers, written by well-regarded authors, cover interesting topics such as the interaction of groundwater and coastal waters, the use of remote sensing for coastal applications, erosion in Arctic environments, the impact of marine vegetation on coastal hydrodynamics, new methods to examine the reliability of breakwater design, the development of marine kinetic energy, and methods for modeling coastal processes as well as their applications to small and large scales, such as a harbor in Hawaii (for design) and the extensive coast of India (for examining the effects of tsunamis and sea level rise). The developments presented in this book could serve not only as a reference book, but also as a starting point for new endeavors in the respective topics.

This review volume, the third in the series, presents the latest topics for discussion, which provides invaluable information to coastal and ocean engineers around the world. In the first paper of this volume, entitled ?Internal Solitary Waves?, Grimshaw reviews the basic theory of weakly nonlinear waves in an incompressible density-stratified fluid. The internal solitary waves solutions and effects such as friction, refraction and finite amplitude on internal solitary waves are also discussed. In the second paper entitled ?The 3/2-Power Law for Ocean Wind Waves and Its Applications?, Toba gives a thorough review on the field evidence and physical background of the 3/2-power law and the associated wind-wave energy spectra. Several wind-wave prediction models are also discussed. Goda, in his paper entitled ?Directional Wave Spectrum and Its Engineering Applications?, gives a brief historical overview of the development of directional wave spectrum. He presents several standard formulas for directional spreading function for engineering applications and discusses the effects of directional spreading on nearshore currents and wave forces on coastal structures. In a companion paper entitled ?Analysis of the Directional Wave Spectrum from Field Data?, Hashimoto describes the maximum entropy principle method, Bayesian directional spectrum estimation method and the extended maximum entropy method for estimating directional wave spectrum. Hashimoto also introduces a new developed Doppler-type directional wave meter for field measurements. Finally, in ?Reliability-Based Design of Coastal Structures?, Barcharth introduces a design procedure that makes it possible to optimize a design and/or to design to a specific failure probability level.

This is a comprehensive, detailed coverage of the subject indicated by the title, embracing all aspects from design criteria over design to construction. Basic wave research, wave structure interaction, hydrodynamics, hydraulics, modelling, solid mechanics, soil mechanics, materials execution, maintenance and equipment are all paid equal attention by highly experienced scientists, engineers and constructors in the field. It is a necessary acquisition for practical wave scientists as well as for technicians and engineers.
