This book is intended as an introduction to classical water wave theory for the college senior or first year graduate student. The material is self-contained; almost all mathematical and engineering concepts are presented or derived in the text, thus making the book accessible to practicing engineers as well.The book commences with a review of fluid mechanics and basic vector concepts. The formulation and solution of the governing boundary value problem for small amplitude waves are developed and the kinematic and pressure fields for short and long waves are explored. The transformation of waves due to variations in depth and their interactions with structures are derived. Wavemaker theories and the statistics of ocean waves are reviewed. The application of the water particle motions and pressure fields are applied to the calculation of wave forces on small and large objects. Extension of the linear theory results to several nonlinear wave properties is presented. Each chapter concludes with a set of homework problems exercising and sometimes extending the material presented in the chapter. An appendix provides a description of nine experiments which can be performed, with little additional equipment, in most wave tank facilities.

This book is intended as a useful handbook for professionals and researchers in the areas of Physical Oceanography, Marine Geology, Coastal Geomorphology and Coastal Engineering and as a text for graduate students in these fields. With its emphasis on boundary layer flow and basic sediment transport modelling, it is meant to help fill the gap between general hydrodynamic texts and descriptive texts on marine and coastal sedimentary processes. The book commences with a review of coastal bottom boundary layer flows including the boundary layer interaction between waves and steady currents. The concept of eddy viscosity for these flows is discussed in depth because of its relation to sediment diffusivity. The quasi-steady processes of sediment transport over flat beds are discussed. Small scale coastal bedforms and the corresponding hydraulic roughness are described. The motion of suspended sand particles is studied in detail with emphasis on the possible suspension maintaining mechanisms in coastal flows. Sediment pickup functions are provided for unsteady flows. A new combined convection-diffusion model is provided for suspended sediment distributions. Different methods of sediment transport model building are presented together with some classical models.

This book treats the subject of sediment transport in the marine environment, covering transport of noncohesive sediment by waves and currents in- and outside the surf zone. It can be read independently, but a background in hydraulics and basic wave mechanics is required.The primary aim of the book is to describe the physical processes of sediment transport and how to represent them in mathematical models. The book can be divided in two main parts; in the first, the relevant hydrodynamic theory is described. This part contains a review of elementary theory for water waves, chapters on the turbulent wave boundary layer and the turbulent interaction between waves and currents, and finally, surf zone hydrodynamics and wave driven currents.The second part covers sediment transport and morphological development.The part on sediment transport introduces the basic concepts (critical bed shear stress, bed load, suspended load and sheet layer, near-bed concentration, effect of sloping bed); it treats suspended sediment in waves and current and in the surf zone, and current and wave-generated bed forms. Finally, the modelling of cross-shore and long-shore sediment transport is described together with the development of coastal profiles and coastlines.

The ocean is the ultimate sink for all liquid waste and has for many years been the recipient of both treated and untreated sewage waste. This book offers a comprehensive study on the subject of ocean disposal of these effluents. The early chapters cover the philosophy of outfall design, properties of sewage from developed towns and an overview of water quality regulations in New Zealand, Great Britain and the U.S. Alternative ways of satisfying these regulations are discussed. The book also provides information required to design outfall pipelines and diffusers. The methods of calculating the initial dilution and the investigations necessary to compute the further dispersion of the effluent are discussed. A brief discussion of the problems of salt water intrusion, of outfall construction and post construction monitoring is presented at the end of the book.

While there are several excellent books dealing with numerical analysis and analytical theory, one has to practically sift through hundreds of references. This monograph is an attempt to partly rectify this situation. It aims to introduce the application of finite-difference methods to ocean dynamics as well as review other complex methods. Systematically presented, the monograph first gives a detailed account of the basics and then go on to discuss the various applications. Recognising the impossibility of covering the entire field of ocean dynamics, the writers have chosen to focus 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. The many aspects covered by this book makes it an indispensable handbook and reference source to both professionals and students of this field.

While the existing literature on offshore structures touch on model testing, a comprehensive text discussing the design, construction, instrumentation, testing and analysis of the physical model is lacking. This book fills that vacuum and provides, through its survey of the theoretical and practical aspects of physical modeling, an in-depth coverage of the technology of model testing. Its usefulness runs through the entire field of engineering, reaching far beyond its focus on offshore construction; and its breadth of scope should appeal not only to engineers and naval architects but to scientists interested in structural or hydraulic testing as well.

Laboratory physical models are a valuable tool for coastal engineers. Physical models help us to understand the complex hydrodynamic processes occurring in the nearshore zone and they provide reliable and economic engineering design solutions.This book is about the art and science of physical modeling as applied in coastal engineering. The aim of the book is to consolidate and synthesize into a single text much of the knowledge about physical modeling that has been developed worldwide.This book was written to serve as a graduate-level text for a course in physical modeling or as a reference text for engineers and researchers engaged in physical modeling and laboratory experimentation. The first three chapters serve as an introduction to similitude and physical models, covering topics such as advantages and disadvantages of physical models, systems of units, dimensional analysis, types of similitude and various hydraulic similitude criteria applicable to coastal engineering models.Practical application of similitude principles to coastal engineering studies is covered in Chapter 4 (Hydrodynamic Models), Chapter 5 (Coastal Structure Models) and Chapter 6 (Sediment Transport Models). These chapters develop the appropriate similitude criteria, discuss inherent laboratory and scale effects and overview the technical literature pertaining to these types of models. The final two chapters focus on the related subjects of laboratory wave generation (Chapter 7) and measurement and analysis techniques (Chapter 8).

This book discusses coastal defense measures, which have not improved in the past few decades, and better alternatives. It emphasizes on the existence of stable bays in coastal geomorphology and their use in coastal stabilization. The conventional measures for saving beaches, such as seawalls, groins, offshore breakwaters, and renourishment, are discussed in detail, followed by an alternative known as headland control. Many types of coast, and the respective defense measures, are discussed, especially for eroding beaches downcoast of harbors with long breakwaters. The formation of offshore bars during storms is examined and the design of stable recreational beaches is demonstrated. Practical design problems are discussed in all cases. Many issues requiring attention in coastal engineering are also outlined.

This book is intended to be a text for undergraduate students of coastal engineering. It also serves as a reference for graduate students and practicing engineers, building on a basic foundation in coastal engineering. Finally, it is a guide for people in related disciplines. Coastal managers may use the book to cover the more theoretical and engineering-related aspects of their trade. Its subject matter is of interest to geographers, planners and coastal scientists alike.

This book presents a theoretical treatment, as well as a summary of practical methods of computation, of the forces and moments that act on marine craft. Its aim is to provide the tools necessary for the prediction or simulation of craft motions in calm water and in waves. In addition to developing the required equations, the author gives relations that permit at least approximate evaluation of the coefficients so that useful results can be obtained. The approach begins with the equations of motion for rigid bodies, relative to fixed- and moving-coordinate systems; then, the hydrodynamic forces are examined, starting with hydrostatics and progressing to the forces on a moving vehicle in calm water and (after a review of water-wave theory) in waves. Several detailed examples are presented, including calculations of hydrostatics, horizontal- and vertical-plane directional stability, and wave-induced motions. Also included are unique discussions on various effects, such as fin–hull interactions, numerical stability of integrators, heavy torpedoes, and the dynamics of high-speed craft. The book is intended to be an introductory-level graduate text and a reference for the practicing professional.

The responses of offshore structures are significantly affected by steep nonlinear waves, currents and wind, leading to phenomena such as springing and ringing of TLPs, slow drift yaw motion of FPSOs and large oscillations of Spar platforms due to vortex shedding. Research has brought about significant progress in this field over the past few decades and introduced us to increasingly involved concepts and their diverse applicability. Thus, an in-depth understanding of steep nonlinear waves and their effects on the responses of offshore structures is essential for safe and effective designs.This book deals with analyses of nonlinear problems encountered in the design of offshore structures, as well as those that are of immediate practical interest to ocean engineers and designers. It presents conclusions drawn from recent research pertinent to nonlinear waves and their effects on the responses of offshore structures. Theories, observations and analyses of laboratory and field experiments are expounded such that the nonlinear effects can be clearly visualized.

This book covers the basics 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 to practical problems. Several case studies are provided to show how the theory outlined in the book is applied in the design of structures. Background material needed for understanding fluid-induced vibrations of structures is given to make the book reasonably self-sufficient. Examples are taken mainly from the novel structures that are of interest today, including ocean and offshore structures and components.Besides being a text for undergraduates, this book can serve as a handy reference for design engineers and consultants involved in the design of structures subjected to dynamics and vibration.

This book treats the subject of local scour around different kinds of marine structures, exposed to waves and/or currents. The first, major part of the book is devoted to marine pipelines, describing in detail all kinds of scour scenarios, and also making recommendations for scour protection. Other kinds of structures considered are single piles (slender or large), groups of piles, complex subsea structures, breakwaters, and seawalls. The scour due to ship propellers is also described. The book deals mainly with the scour in noncohesive sediment but, whenever possible, available literature on the scour in finer sediment has been incorporated. In addition, a chapter on the impact of wave-induced liquefaction is included.The authors' aim is to describe in detail the hydrodynamic processes causing the erosion. With a hydrodynamic understanding, it is easier for the consulting engineer to predict scour in those many cases where physical model tests are not available.

This timely book is about how to design alternatives to reduce coastal flood and wave damage, erosion, and loss of ecosystems facing an unknown future of sea level rise. The latest theories are interlaced with applied examples from the authors' 48 years of experience in teaching, research, and as a practicing, professional engineer in coastal engineering. The design process takes into consideration all the design constraints (scientific, engineering, economic, environmental, social/political/institutional, aesthetic, and media) to meet today's client needs, expectations, and budgets for an uncertain future.The book is organized as a textbook for graduate students. And, it is a self-contained reference for government and consulting engineers responsible for finding solutions to coastal hazards facing the world's coastal populations. New solutions are included in the book that help people of all socio-economic levels living at the coast. Both risk reduction metrics quantified in monetary terms, and increased resilience metrics quantified as vulnerability reduction must now be taken into consideration to make equitable design decisions on hazard mitigation alternatives.In the Anthropocene Era, under "deep uncertainty" in global mean sea level predictions for the future, today's designs must mitigate today's storm damages, and be adaptable for the unpredictable water levels and storms of the future. This book includes a design "philosophy" for water levels to year 2050 and for the long term from 2050 to 2100. Multiple spreadsheets are provided and organized to aid the design process.This is an exciting time to be "thinkers" as Civil/Coastal engineers.Related Link(s);

This book is based on the author's 49 years of experience as a practicing coastal engineer and 34 years as professor of coastal engineering and management at Queen's University. The book is therefore thoroughly practical in nature, but it also reflects newly relevant issues, such as consequences of failure, impacts of rising sea levels, aging infrastructure, real estate development, and contemporary decision making, design and education.This textbook is useful for undergraduate students, postgraduate students and practicing engineers. It covers waves, structures, sediment movement, coastal management, and contemporary coastal design and decision making. It presents both basic principles and engineering solutions. It discusses the traditional methods of analysis and synthesis (design), but also contemporary design methodologies, such as working with environmental impacts.The second edition expanded greatly on the topics of failure and resilience that surfaced as a result of recent disasters from hurricane surges and tsunamis. It updated the discussion of design and decision making for the 21st century, with many new examples.This third edition develops some of these topics further, but its largest new changes is the chapter on climate change. This chapter presents the basics of climate change and then goes on to stress the practical implications of the impacts of climate change, focusing on what is of importance to coastal and fluvial specialists.

The aim of the book is to consolidate and synthesize into a single text much of the knowledge about physical modeling that has been developed worldwide.This book was written to serve as a graduate-level text for a course in physical modeling or as a reference text for engineers and researchers engaged in physical modeling and laboratory experimentation. The first three chapters serve as an introduction to similitude and physical models, covering topics such as advantages and disadvantages of physical models, systems of units, dimensional analysis, types of similitude and various hydraulic similitude criteria applicable to coastal engineering models.Practical application of similitude principles to coastal engineering studies is covered in Chapter 4 (Hydrodynamic Models), Chapter 5 (Coastal Structure Models) and Chapter 6 (Sediment Transport Models). These chapters develop the appropriate similitude criteria, discuss inherent laboratory and scale effects and overview the technical literature pertaining to these types of models. The final two chapters focus on the related subjects of laboratory wave generation (Chapter 7) and measurement and analysis techniques (Chapter 8).

This book is written for engineers, students of coastal processes and laypersons interested in beach nourishment, which consists of 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. The overall longevity of a project is addressed as are local erosional areas. The roles which wave height, project length and sediment quality play in project performance are addressed quantitatively. The results are illustrated through reference to a number of monitored nourishment projects. Biological and economic aspects of beach nourishment are addressed.

This is the first book on explosion-generated water waves. It presents the theoretical foundations and experimental results of the generation and propagation of impulsively generated waves resulting from underwater explosions. Many of the theories and concepts presented herein are applicable to other types of water waves, in particular, tsunamis and waves generated by the fall of a meteorite. Linear and nonlinear theories, as well as experimental calibrations, are presented for cases of deep and shallow water explosions. Propagation of transient waves on dissipative, nonuniform bathymetries together with laboratory simulations are analyzed and discussed.

This book discusses coastal defense measures, which have not improved in the past few decades, and better alternatives. It emphasizes on the existence of stable bays in coastal geomorphology and their use in coastal stabilization. The conventional measures for saving beaches, such as seawalls, groins, offshore breakwaters, and renourishment, are discussed in detail, followed by an alternative known as headland control. Many types of coast, and the respective defense measures, are discussed, especially for eroding beaches downcoast of harbors with long breakwaters. The formation of offshore bars during storms is examined and the design of stable recreational beaches is demonstrated. Practical design problems are discussed in all cases. Many issues requiring attention in coastal engineering are also outlined.

This book is intended to be a text for undergraduate students of coastal engineering. It also serves as a reference for graduate students and practicing engineers, building on a basic foundation in coastal engineering. Finally, it is a guide for people in related disciplines. Coastal managers may use the book to cover the more theoretical and engineering-related aspects of their trade. Its subject matter is of interest to geographers, planners and coastal scientists alike.

This book presents a theoretical treatment, as well as a summary of practical methods of computation, of the forces and moments that act on marine craft. Its aim is to provide the tools necessary for the prediction or simulation of craft motions in calm water and in waves. In addition to developing the required equations, the author gives relations that permit at least approximate evaluation of the coefficients so that useful results can be obtained. The approach begins with the equations of motion for rigid bodies, relative to fixed- and moving-coordinate systems; then, the hydrodynamic forces are examined, starting with hydrostatics and progressing to the forces on a moving vehicle in calm water and (after a review of water-wave theory) in waves. Several detailed examples are presented, including calculations of hydrostatics, horizontal- and vertical-plane directional stability, and wave-induced motions. Also included are unique discussions on various effects, such as fin–hull interactions, numerical stability of integrators, heavy torpedoes, and the dynamics of high-speed craft. The book is intended to be an introductory-level graduate text and a reference for the practicing professional.

The responses of offshore structures are significantly affected by steep nonlinear waves, currents and wind, leading to phenomena such as springing and ringing of TLPs, slow drift yaw motion of FPSOs and large oscillations of Spar platforms due to vortex shedding. Research has brought about significant progress in this field over the past few decades and introduced us to increasingly involved concepts and their diverse applicability. Thus, an in-depth understanding of steep nonlinear waves and their effects on the responses of offshore structures is essential for safe and effective designs.This book deals with analyses of nonlinear problems encountered in the design of offshore structures, as well as those that are of immediate practical interest to ocean engineers and designers. It presents conclusions drawn from recent research pertinent to nonlinear waves and their effects on the responses of offshore structures. Theories, observations and analyses of laboratory and field experiments are expounded such that the nonlinear effects can be clearly visualized.

This book covers the basics 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 to practical problems. Several case studies are provided to show how the theory outlined in the book is applied in the design of structures. Background material needed for understanding fluid-induced vibrations of structures is given to make the book reasonably self-sufficient. Examples are taken mainly from the novel structures that are of interest today, including ocean and offshore structures and components.Besides being a text for undergraduates, this book can serve as a handy reference for design engineers and consultants involved in the design of structures subjected to dynamics and vibration.

This book treats the subject of local scour around different kinds of marine structures, exposed to waves and/or currents. The first, major part of the book is devoted to marine pipelines, describing in detail all kinds of scour scenarios, and also making recommendations for scour protection. Other kinds of structures considered are single piles (slender or large), groups of piles, complex subsea structures, breakwaters, and seawalls. The scour due to ship propellers is also described. The book deals mainly with the scour in noncohesive sediment but, whenever possible, available literature on the scour in finer sediment has been incorporated. In addition, a chapter on the impact of wave-induced liquefaction is included.The authors' aim is to describe in detail the hydrodynamic processes causing the erosion. With a hydrodynamic understanding, it is easier for the consulting engineer to predict scour in those many cases where physical model tests are not available.

This timely book is about how to design alternatives to reduce coastal flood and wave damage, erosion, and loss of ecosystems facing an unknown future of sea level rise. The latest theories are interlaced with applied examples from the authors' 48 years of experience in teaching, research, and as a practicing, professional engineer in coastal engineering. The design process takes into consideration all the design constraints (scientific, engineering, economic, environmental, social/political/institutional, aesthetic, and media) to meet today's client needs, expectations, and budgets for an uncertain future.The book is organized as a textbook for graduate students. And, it is a self-contained reference for government and consulting engineers responsible for finding solutions to coastal hazards facing the world's coastal populations. New solutions are included in the book that help people of all socio-economic levels living at the coast. Both risk reduction metrics quantified in monetary terms, and increased resilience metrics quantified as vulnerability reduction must now be taken into consideration to make equitable design decisions on hazard mitigation alternatives.In the Anthropocene Era, under "deep uncertainty" in global mean sea level predictions for the future, today's designs must mitigate today's storm damages, and be adaptable for the unpredictable water levels and storms of the future. This book includes a design "philosophy" for water levels to year 2050 and for the long term from 2050 to 2100. Multiple spreadsheets are provided and organized to aid the design process.This is an exciting time to be "thinkers" as Civil/Coastal engineers.Related Link(s);

This book is based on the author's 49 years of experience as a practicing coastal engineer and 34 years as professor of coastal engineering and management at Queen's University. The book is therefore thoroughly practical in nature, but it also reflects newly relevant issues, such as consequences of failure, impacts of rising sea levels, aging infrastructure, real estate development, and contemporary decision making, design and education.This textbook is useful for undergraduate students, postgraduate students and practicing engineers. It covers waves, structures, sediment movement, coastal management, and contemporary coastal design and decision making. It presents both basic principles and engineering solutions. It discusses the traditional methods of analysis and synthesis (design), but also contemporary design methodologies, such as working with environmental impacts.The second edition expanded greatly on the topics of failure and resilience that surfaced as a result of recent disasters from hurricane surges and tsunamis. It updated the discussion of design and decision making for the 21st century, with many new examples.This third edition develops some of these topics further, but its largest new changes is the chapter on climate change. This chapter presents the basics of climate change and then goes on to stress the practical implications of the impacts of climate change, focusing on what is of importance to coastal and fluvial specialists.
