The world's shorelines are geologic environments unique in their composition and the physical processes affecting them. Shoreline development is now causing a significant conflict with natural coastal processes. This text helps students understand these coastal processes and develop strategies to cope effectively with shoreline erosion. The book is organized in four parts: (1) an overview of coastal engineering, using case studies to illustrate problems; (2) hydrodynamics of the coastal zone, reviewing storm surges, water waves, and low frequency motions within the nearshore and surf zone; (3) coastal responses including equilibrium beach profiles and sediment transport; (4) applications such as erosion mitigation, beach nourishment, coastal armoring, tidal inlets, and shoreline management. Numerous home problems and references are key features.

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 covers water waves, surf zone hydrodynamics, tides in oceans and estuaries, storm surges, estuarine mixing, basic sediment transport, coastal morphodynamics and coastal groundwater dynamics. It is an introductory treatment, suitable for a first course in coastal and estuarine processes for earth scientists or engineers. Yet, there are substantial amounts of new material that are included, such as the explicit, analytical treatment of transient, forced long waves. Inclusion of this material will in turn strongly enhance the introductory treatment of tsunami, storm surges and surf beat. The treatment of sine wave theory emphasizes expressions which are explicit in the water depth h (using koh instead of kh) so that they can easily be differentiated or integrated with respect to h. This is a major pedagogical advantage because of the enhanced transparency. The treatment of turbulent mixing includes finite mixing length effects which provide an explanation for differential diffusion of different sediment sizes in suspension. The effects of acceleration skewness and boundary layer streaming are also included in the basic sediment transport models. The inclusion of beach groundwater dynamics — including the mechanisms by which waves as well as tides drive groundwater motion — provides a link between the previously unconnected fields of coastal hydraulics and regional groundwater modeling. Serving as a good reference book, it is fully indexed and comprehensively cross referenced. Abundant references to more detailed texts are also provided.

The second edition (1997) of this text was a completely rewritten version of the original text Basic Coastal Engineering published in 1978. This third edition makes several corrections, improvements and additions to the second edition. Basic Coastal Engineering is an introductory text on wave mechanics and coastal processes along with fundamentals that underline the practice of coastal engineering. This book was written for a senior or first postgraduate course in coastal engineering. It is also suitable for self study by anyone having a basic engineering or physical science background. The level of coverage does not require a math or fluid mechanics background beyond that presented in a typical undergraduate civil or mechanical engineering curriculum. The material p- sented in this text is based on the author’s lecture notes from a one-semester course at Virginia Polytechnic Institute, Texas A&M University, and George Washington University, and a senior elective course at Lehigh University. The text contains examples to demonstrate the various analysis techniques that are presented and each chapter (except the first and last) has a collection of problems for the reader to solve that further demonstrate and expand upon the text material. Chapter 1 briefly describes the coastal environment and introduces the re- tively new field of coastal engineering. Chapter 2 describes the two-dimensional characteristics of surface waves and presents the small-amplitude wave theory to support this description.

The United Nations estimate that by 2004, in excess of 75% of the world's population will live within the coastal zone. These regions are therefore of critical importance to a majority of the world's citizens. The coastal zone provides important economic, transport, residential and recreational functions, all of which depend upon its physical characteristics, appealing landscape, cultural heritage, natural resources and rich marine and terrestrial biodiversity. This resource is thus the foundation for the well being and economic viability of present and future generations of coastal zone residents The pressure on coastal environments is also being exacerbated by rapid changes in global climate. The value of the coastal zone to humanity, and the enormous pressure on it, provide strong incentives for a greater scientific understanding which can ensure effective coastal engineering practice and efficient and sustainable management. Coastal Engineering: Processes, Theory and Design Practice is the only book providing a thorough introduction to all aspects of coastal processes, morphology and design of coastal defences. The use of detailed and state-of-the art modelling techniques are an important theme of this book, and there are numerous case studies showing actual examples where mathematical modelling has been applied through engineering judgement. With thorough coverage of the theory, and practical demonstration of the applications, Coastal Engineering: Processes, Theory and Design Practice is a must have for all students and engineers working in coastal management and engineering. .

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.

Mechanistic models are often employed to simulate processes in coastal environments. However, these predictive tools are highly specialized, involve certain assumptions and limitations, and can be manipulated only by experienced engineers who have a thorough understanding of the underlying principles. This results in significant constraints on their manipulation as well as large gaps in understanding and expectations between the developers and users of a model. Recent advancements in soft computing technologies make it possible to integrate machine learning capabilities into numerical modelling systems in order to bridge the gaps and lessen the demands on human experts. This book reviews the state-of-the-art in conventional coastal modelling as well as in the increasingly popular integration of various artificial intelligence technologies into coastal modelling. Conventional hydrodynamic and water quality modelling techniques comprise finite difference and finite element methods. The novel algorithms and methods include knowledge-based systems, genetic algorithms, artificial neural networks, and fuzzy inference systems. Different soft computing methods contribute towards accurate and reliable prediction of coastal processes. Combining these techniques and harnessing their benefits has the potential to make extremely powerful modelling tools.

Waves in Oceanic and Coastal Waters describes the observation, analysis and prediction of wind-generated waves in the open ocean, in shelf seas, and in coastal regions with islands, channels, tidal flats and inlets, estuaries, fjords and lagoons. Most of this richly illustrated book is devoted to the physical aspects of waves. After introducing observation techniques for waves, both at sea and from space, the book defines the parameters that characterise waves. Using basic statistical and physical concepts, the author discusses the prediction of waves in oceanic and coastal waters, first in terms of generalised observations, and then in terms of the more theoretical framework of the spectral energy balance. He gives the results of established theories and also the direction in which research is developing. The book ends with a description of SWAN (Simulating Waves Nearshore), the preferred computer model of the engineering community for predicting waves in coastal waters.

This book treats the subject of sediment transport in the marine environment, covering transport of non-cohesive sediment by waves and current in- and outside the surf zone. It can be read independently, but a background in hydraulics and basic wave mechanics is required. It is intended for M.Sc. and Ph.D. students. The primary aim of the book is to describe the physical processes of sediment transport and how to represent them in mathematical models. It does not present a large number of different formulae for the sediment transport rates under various conditions. The book can be divided in two main parts; in the first, the relevant hydrodynamic theory is described; in the second, sediment transport and morphological development are treated. The hydrodynamic 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 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.

Following on the success of the first conference, the Wessex Institute of Technology is convening the Second International Conference on Physical Coastal Processes, Management and Engineering. This book contains papers to be presented at that Conference. Coastal zone dynamics involve distinctive features that stem from both near shore hydrodynamics, and the complex local behaviour of the atmosphere that is affected by the irregularity of the coastal topography and variations in land sea surface roughness and thermal properties. Complex interactions occur between the atmosphere, ocean and land, leading to large temporal and spatial differences in air-sea exchange processes and wind strength and direction. Recreational and tourism demand on coastal areas activities makes increased shore and beach protection necessary. Coastlines are often subjected to direct impact of wind, swell and storm wave activity. Many other physical phenomena, such as tides and associated currents, long waves and storm surges, also affect the dynamic behaviour of the coastal zone. With the increase in extreme events due to climate change, the role of extreme events in changing coastal zones needs to be considered. The International Conference will consider also of these and will cover such topics as: Wave modelling; Wave transformation hydrodynamics; Extreme events and sea level rise; Sea defences; Interaction between coastal defences and processes; Energy recovery; Hydrodynamic forces; Sediment transport and erosion; Pollution and dispersion; Planning and beach design; Coastal geomorphology; Coastal processes and navigation; Coastal processes and GIS; Bio-physical coastal processes; and Great Lakes problems. The book will be of interest to engineers and government officials involved with coastal zone management and development

The world's coastlines represent a myriad of dynamic and constantly changing environments. Heavily settled and intensely used areas, they are of enormous importance to humans and understanding how they are shaped and change is crucial to our future. Introduction to Coastal Processes and Geomorphologybegins by discussing coastal systems and shows how these systems link to the processes examined in detail throughout the book. These include the morphodynamic paradigm, tides, waves and sediment transport. Later chapters explore fluvial deltas, estuaries, beaches and barriers, coastal sand dunes and geologically-influenced coasts such as cliffs, coral reefs and atolls. A new chapter addresses the forward-facing aspect of coastal morphodynamics, including the ways in which coasts respond to rapid climate changes such as present day global warming. Also new to this second edition is a chapter on future coasts which considers the wider effects of coastal change on other important aspects of coastal systems, including ecology, management, socio-cultural activities, built and natural heritage, and archaeology. Case studies using examples from around the world illustrate theory in practice and bring the subject to life. Each chapter starts by outlining the 'aims' and questions at the end allow you to track your progress. This book is accompanied by additional resources online at www.hodderplus.com/geography including: Answers to the questions available to download as MP3 files Expanded case studies with colour photos, links to relevant websites and a map link to pinpoint the case study location Interactive multiple choice questions and worked examples The ebook edition is in VitalBookTM Bookshelf - an ebook reader which allows you to: download the ebook to your computer or access it anywhere with an internet browser search the full text of all of the ebooks that you hold on your bookshelf for instant access to the information you need make and share notes and highlights on your ebooks copy and print text and figures customize your view by changing font size and layout.
