Bücher der Reihe Advanced Series On Ocean Engineering

This work focuses on topics including the physics of the fundamental dynamics of fluids and of semi-immersed Lagrangian solid bodies that are responding to wave-induced loads and the scaling of dimensional equations and boundary value problems.

This monograph aims at presenting a unified approach to numerical modeling of tsunami as long waves based on finite difference methods for 1D, 2D and 3D generation processes, propagation, and runup. Many practical examples give insight into the relationship between long wave physics and numerical solutions and allow readers to quickly pursue and develop specific topics in greater depth. The aim of this book is to start from basics and then continue into applications. This approach should serve well the needs of researchers and students of physics, physical oceanography, ocean/civil engineers, computer science, and emergency management staff. Chapter 2 is particularly valuable as it fully describes the application of finite-difference methods to the study of long waves by demonstrating how physical properties of water waves, especially phase velocity, are connected to the chosen numerical algorithm. Basic notions of numerical methods, i.e. approximation of the relevant differential equations, stability of the numerical scheme, and computational errors are explained through application to long waves. Finite-difference methods are further developed in major chapters to deal with complex problems that arise in the study of recent tsunamis.

The increase in exploration and exploitation of ocean resources, maritime trade and ocean energy have led to development of new concepts in the study of coastal and marine structures. These developments necessitate comprehensive and in-depth knowledge of ocean wave behavior in the offshore as well as in the nearshore, such as the phenomena of wave generation, propagation, deformation and its effects, which help to enlighten our understanding of its influence on coastal and offshore structures.Ocean Wave Dynamics for Coastal and Marine Structures is a recommended textbook for students and researchers in ocean sciences, engineering and related topics. It offers application of theoretical formulae to practical relevance through problem solving. This book will also be invaluable for professionals in ports, offshore and marine industries as well as consulting companies.

Headland-bay beaches (HBBs) are ubiquitous in coastal environment.

Dealing with the basics of ocean dynamics and various applications, this book focuses on transport equations (diffusion and advection), shallow water phenomena - tides, storm surges and tsunamis; three-dimensional time dependent oceanic motion; natural oscillations; and steady state phenomena.

Synthetic-aperture radar (SAR) as a form of radar to create images of objects, uses the motion of the radar antenna over a targeted region to provide finer spatial resolution than is possible with conventional beam-scanning radars by mounting the antenna on a moving platform such as an aircraft or spacecraft. As antenna aperture (the ''size'' of the antenna) is defined by the distance the SAR device travels over a target in the time taken for the radar pulses to return to the antenna, the larger the aperture is, the higher the image resolution, therefore, this enables SAR to create high resolution images with comparatively small physical antennas.This special book aims to provide the updated theories and methods for the use of synthetic aperture radar (SAR) onboard satellites to detect ocean processes, i.e., SAR ocean remote sensing. It is a hi-tech application field having been developed since late 1970s and become a powerful tool for obtaining dynamic signatures from the remote and broad ocean.

Aiming to describe from a deterministic point of view the sediment transport in the general wave-current situation, the book is divided into two parts, the first treating flow and turbulence in combined wave-current, the second the sediment transport as a result of the wave-current action.

This volume includes a host of methods for retaining sediment on the coastal areas where it is required. Examples of stabilization methods are taken from many countries, but the emphasis is on oceanic margins, headland control, erosion prevention and other defence measures.

Beach nourishment comprises 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.

Discusses the art and science of physical modelling as applied in coastal engineering. Topics covered include: advantages and disadvantages of physical models; systems of units; dimensional analysis; types of similitude; and avarious hydraulic similitude criteria.

This book presents observations on the phenomena of fine sediment transport and their explanations under process-related divisions such as flocculation, erosion, and deposition.The text is a compilation of the author''s lecture notes from nearly four decades of teaching and guiding graduate students in civil and coastal engineering. Illustrations of fine sediment transport processes and their complexities given in the book are taken from field and laboratory-based observations by the author and his students, as well as numerous investigators.The wide-ranging composition of particles (of inorganic and organic matter), their universal presence and their complex interactions with hydraulic forces make this branch of science a difficult one to deal with in a single treatise. It is therefore essential to study fine sediment transport as an independent subject rather than cover it in no more than a single chapter as many texts on coarse sediment transport have done.Even though the entire coverage is ΓÇ£introductoryΓÇ¥, the twelve chapters collectively include more material than what can be reasonably dealt with in a one semester, three-credit course.The book includes an extensive description of the components of fine-grained ΓÇö especially cohesive ΓÇö sediment transport. It covers the development of the subject in scientific and engineering applications mainly from the 1950s to its present state. Solved examples and chapter-end exercises are also included.This text is aimed at senior civil engineering undergraduates and graduate students who, in the normal course of their study, seldom come across the subject of fine sediment transport in their curricula. Interested students should have a basic understanding of the mechanics of fluid flow and open channel hydraulics.

A study of local scour around different kinds of marine structures exposed to waves and/or currents. The first, major part of the work is devoted to marine pipelines. Other kinds of structures considered are single piles, groups of piles, complex sub-sea structures, breakwaters, and seawalls.

Modern design of berm breakwaters began about thirty years ago. However, to date, there has been a lack of a well-established, formal design methodology on berm breakwaters.

This book can potentially serve as a comprehensive textbook for students pursuing this subject either as degree or an elective course. It covers all the fundamental physics behind the different phenomena taking place in the near shore regions and the coast as well as the various methods to estimate its impact. Basic knowledge of water wave mechanics is crucial in understanding the coastal processes taking place in the near shore. The assessment of incident forces due to wind, wave, tide, current etc. is important to evaluate the resultant impact they cause on the shoreline and structures.This book emphasizes the importance of sediment dynamics by analyzing the sediment characteristics, the physics of its motion and movement, factors responsible for the fate of sediments etc. It also highlights the erosion problem which is most prevalent across the sandy coasts, additionally erosion combating methods and techniques are also described with real time field problems and their solutions.A wide range of coastal structures and their design principles are included in this book in order to give the reader a holistic understanding to the readers. This book also includes the design challenges and introduces the reliable modeling tools and techniques, which is very useful for beginners working in this discipline.

This book: describes precious lessons obtained from actual tsunami disasters; imparts fundamental knowledge of tsunami science for survival; and, lists measures for tsunami disaster mitigation. It also describes tsunami occurrence mechanism and near-shore behavior.

This book provides a comprehensive description of the latest theory-supported numerical technologies, as well as scientific and engineering applications for water surface waves. Its contents are crafted to cater to a step-by-step learning of computational wave dynamics and ocean wave modeling. It provides a comprehensive description from underlying theories of free-surface flows, to practical computational applications for coastal and ocean engineering on the basis of computational fluid dynamics (CFD). The text may be used as a textbook for advanced undergraduate students and graduate students to understand the theoretical background of wave computations, and the recent progress of computational techniques for free-surface and interfacial flows, such as Volume of Fluid (VOF), Constrained Interpolation Profile (CIP), Lagrangian Particle (SPH, MPS), Distinct Element (DEM) and Euler-Lagrange Hybrid Methods. It is also suitable for researchers and engineers who wish to apply CFD techniques to ocean modeling and practical coastal problems involving sediment transport, wave-structure interaction and surf zone flows.

The most pertinent tsunami related issues such as water borne debris during tsunami flooding, design loads to incorporate for impact forces on coastal zone infrastructure, detection and warning are meticulously incorporated in this book.Modelling of various coastal processes have proven to be successful in the recent past, which includes extreme events such as storm surge, cyclone, etc. The possible provisions for computational/numerical tsunami modelling and real physical modelling in laboratory are elaborated. The propagation, evolution and run-up of tsunami waves and their associated non-linear dynamics are discussed.The significant inferences from the experts who have had hands-on experience working with the extensive magnitude of a tsunami disaster reported on the signature studies and post-facto effects of the 2004 Indian Ocean Tsunami, with respect to the damages along the Indian coast.

Beaches in Japan have been eroding since the 1970s because of artificial land alterations and unsustainable coastal development. Almost all causes of the beach erosion in Japan are due to anthropogenic factors - as a result of human activity. This book presents the state of the beaches throughout Japan, looking at the current reality and the classification of causes of beach erosion using real-life, illustrated examples. It then goes on to look at practical models which can be used to predict changes to different types of beaches, and concludes with investigation of beach erosion as a wider structural problem. Lessons learnt show the manner in which excessive coastal development without clearly identified measures for beach protection can have widespread global ramifications.This second edition presents new findings from field studies carried out on Japanese beaches, along with the development and improvement of the numerical model presented previously. In addition to the first edition, six new examples of the beach erosion in Japan are included, as is new analysis of the BG model (a model for predicting based on Bagnold's concept), which can be applicable to various field problems.Originally published in Japanese (2004), this updated version gives clear practical guidance to coastal engineers working to prevent irreversible beach erosion and sustainable coastal development policy.

This book aims is to describe the flow pattern and the resulting load which develops when waves or current meet a cylinder.

A study of the hydrodynamics and vibration of structures subjected to environmental loads. It describes the interaction of hydrodynamics with the associated vibration of structures, giving simple explanations. Emphasis is placed on the applications of the theory and case studies are included.

Random waves are the most important constituent of the sea environment, as they make the design of maritime structures quite different from that of structures on land. This book explores the concept of random waves for the design of breakwaters, seawalls, and harbor structures for easy comprehension by practicing engineers.
