Coast lines have been and still are the centre lines of civilization around the world with still increasing pressure from both sides, the hinterland and the sea, with all its foreseeable and unforeseeable impacts given by nature or mankind. While response of nature to such impacts is flexible in the way that all morphological changes with all the consequences are tolerated as part of the system, man cannot tolerate short-term or long-term changes without being threatened in its physical and economical existence. The objectives of this Advanced Research Workshop (ARW) on Environmentally Friendly Coastal Structures were: - to contribute to the critical assessment of existing knowledge in the field of coastal and environmental protection; - to identify directions for future research in that area; - to promote close working relationships between scientists from different countries and with different professional experience. Latest trends in research in coastal and environmental protection have been summarized and developed during the meeting. Seventeen papers are presented in this book, attempting to cover as completely as possible all related aspects a" coast, engineering structures, water, sediments, ecosystems in their complicated interaction.
Open channel hydraulics has always been a very interesting domain of scienti c and engineering activity because of the great importance of water for human l- ing. The free surface ow, which takes place in the oceans, seas and rivers, can be still regarded as one of the most complex physical processes in the environment. The rst source of dif culties is the proper recognition of physical ow processes and their mathematical description. The second one is related to the solution of the derived equations. The equations arising in hydrodynamics are rather comp- cated and, except some much idealized cases, their solution requires application of the numerical methods. For this reason the great progress in open channel ow modeling that took place during last 40 years paralleled the progress in computer technique, informatics and numerical methods. It is well known that even ty- cal hydraulic engineering problems need applications of computer codes. Thus, we witness a rapid development of ready-made packages, which are widely d- seminated and offered for engineers. However, it seems necessary for their users to be familiar with some fundamentals of numerical methods and computational techniques applied for solving the problems of interest. This is helpful for many r- sons. The ready-made packages can be effectively and safely applied on condition that the users know their possibilities and limitations. For instance, such knowledge is indispensable to distinguish in the obtained solutions the effects coming from the considered physical processes and those caused by numerical artifacts.
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.
Analysis of open-channel flow is essential for the planning, design, and operation of water-resource projects. The use of computers and the availability of efficient computational procedures has simplified such analysis, and made it possible to handle increasingly complex systems. In Open-Channel Flow, Second Edition, author Hanif Chaudhry draws upon years of practical experience and incorporates numerous examples and real life applications, to provide the reader with:
Open-Channel Flow, Second Edition is written for students in senior-level undergraduate and graduate courses on steady and unsteady open-channel flow and for civil engineers needing up-to-date and relevant information on the latest developments and techniques in the field.
Nominated by Tsinghua University as an outstanding Ph.D. thesis, this book investigates the mechanical properties of unsaturated compacted clayey soil, the multi-field coupling consolidation theory of unsaturated soil and its application to a 261.5 m high earth-rockfill dam. It proposes a multi-field coupling analysis method of consolidation, and develops an efficient and practical finite element (FE) program for large-scale complex earth-rockfill dams. The book is primarily intended for researchers studying the multi-field coupling analysis of seepage consolidation.
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.
These proceedings of a NATO Advanced Research Workshop on "Environmental Reconstruction in Headwater Areas" provide a landmark in the evolution of a distinctive movement, perhaps an emerging new philosophy, within the practice of headwater management. The Headwater Control movement traces its history back to the First International Conference on Headwater Control, Prague, 1989. Throughout this brief history, Headwater Control has remained a typical environment movement 'ad hocracy'. At its meetings, for every convert to the multidisciplinary, integrative, practical, interventionist, and above-all 'green' ideals of the group, there have been several delegates who have found the whole concept both new and slightly incomprehensible. One reason for this has been the Headwater Control practice of trying to bring together scientists, practitioners, policy-makers and non-government environmentalist organisations. The group's larger meetings have always been federal gatherings. Sponsorship has been shared with invited participation from associations representing hydrological science, soil conservation, erosion control, forestry, environmental activism and so forth. These delegations may have included fellow travellers in the work to protect headwater environments, but their main concerns have not necessarily coincided with the Headwater Control group's prescriptions for the environmental regeneration of headwater regions. The Liberec Workshop, whose proceedings are distilled into this volume, provided a first opportunity for the scattered supporters of Headwater Control to talk among themselves and fmd out to what degree there really is a shared vision of the way forward in headwater management, restoration and protection.
In the world of transportation, fatigue is a silent killer that can affect us all. Understanding fatigue, including how to manage it to minimize safety risk, is of great importance. However, while it is one thing to recognize that fatigue is a critical safety issue, it is quite another to set up a successful, scientifically informed fatigue risk management programme. This book is here to help. It has been carefully designed as a comprehensive reference point, bringing together international expertise from leaders in fatigue science, and showcasing valuable insights from transportation industry practitioners. The 40 authored chapters are divided into six sections, to better understand fatigue science, the consequences of fatigue in transportation, contributors to fatigue, managing fatigue and promoting alertness, real world case studies of fatigue management in practice, and future perspectives. While it is possible to read each chapter in isolation, most will be gained by reading the book as a whole. Each chapter starts with an abstract overview and concludes with summary bullet points, creating a handy "quick check" for key points. This accessible text is for those who are interested in supporting alert and safe transportation operations. It is suitable for professionals, transport managers, government advisors, policy makers, students, academics, and anyone who wants to learn more. All transport modes (road, rail, maritime and aviation) are considered. For anyone waking up to the complex challenge of fatigue management, this handbook is a must.
Each year more than 200 million people are affected by floods, tropical storms, droughts, earthquakes, and also operational failures, wars, terrorism, vandalism, and accidents involving hazardous materials. These are part of the wide variety of events that cause death, injury, and significant economic losses for the countries affected. In an environment where natural hazards are present, local actions are decisive in all stages of risk management: in the work of prevention and mitigation, in rehabilitation and reconstruction, and above all in emergency response and the provision of basic services to the affected population. Commitment to systematic vulnerability reduction is crucial to ensure the resilience of communities and populations to the impact of natural and manmade hazards. Current challenges for the water and sanitation sector require an increase in sustainable access to water and sanitation services in residential areas, where natural hazards pose the greatest risk. In settlements located on unstable and risk-prone land there is growing environmental degradation coupled with extreme conditions of poverty that increase vulnerability. The development of local capacity and risk management play vital roles in obtaining sustainability of water and sanitation systems as well as for the communities themselves. Unfortunately water may also represent a potential target for terrorist activity or war conflict and a deliberate contamination of water is a potential public health threat. An approach which considers the needs of communities and institutions is particularly important in urban areas affected by armed conflict. Risk management for large rehabilitation projects has to deal with major changes caused by conflict: damaged or destroyed infrastructure, increased population, corrupt or inefficient water utilities, and impoverished communities. Water supply and sanitation are amongst the first considerations in disaster response. The greatest water-borne risk to health in most emergencies is the transmission of faecal pathogens, due to inadequate sanitation, hygiene and protection of water sources. However, some disasters, including those involving damage to chemical and nuclear industrial installations, or involving volcanic activity, may create acute problems from chemical or radiological water pollution. Sanitation includes safe excreta disposal, drainage of wastewater and rainwater, solid waste disposal and vector control. This book is based on the discussions and papers prepared for the NATO Advanced Research Workshop that took place in Ohrid, Macedonia under the auspices of the NATO Security Through Science Programme and addressed problems Risk management of water supply and sanitation systems impaired by operational failures, natural disasters and war conflicts. The main purpose of the workshop was to critically assess the existing knowledge on Risk management of water supply and sanitation systems, with respect to diverse conditions in participating countries, and promote close co-operation among scientists with different professional experience from different countries. The ARW technical program comprised papers on 4 topics: (a) Vulnerability of Wastewater and Sanitation Systems, (b) Vulnerability of Drinking Water Systems, (c) Emergency response plans, and (d) Case studies from regions affected by Drinking Water System, Wastewater and Sanitation System failures.
The increasing risk of severe droughts and water shortages emphasizes the need for an integrated approach to drought mitigation. However, effective tools for the implementation of such an approach have not been available till now. This book contributes to an improved preparedness for drought in water supply systems, providing tools useful for a better decision making process in drought management. It presents methods and software features of a Decision Support System (DSS) developed within a European research project and consists of three main parts. The first part deals with the advanced techniques for hydrological drought identification and monitoring; the second analyses the successful use of climate-crop-soil models in defining deficit irrigation strategies; the third provides tools for improving the operation of irrigation supply reservoirs. All methods are embedded in a user-friendly DSS package that has been applied in several Case Studies of Mediterranean countries (Portugal, Italy, Tunisia, Jordan and Syria) and whose results are also compared.
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).

Triggerd primarily byill effects of polluted air, soil and water resources on living species, public concern for environmental quality has been growing during the past four decades or so. One manifestation of this concern is found in occurrence of public debates as well as in the demand for full environmental impact assessment before a water-resources project is approved. Engineering soundness and economic feasibility are no longer sufficient criteria for construction of hydraulic works. As a result, environmental considerations have become very much a part of hydraulic analyses. In response to growing environmental concerns, the field of hydraulics has expanded and a new branch, called Environmental Hydraulics, has emerged. The focus of this branch is on hydraulic analyses of those environmental issues that are important for protection, restoration, and managementof environmental quality. The motivation for this book grew out of the desire to provide a hydraulic discussion of some of the key environmental issues.It is hoped that the book would serve to stimulate others to write more comprehensive texts on this subject of growing importance.
The three parts of this volume - Technical Refinement; Technical Innovation; and Project Management and Risk Minimisation - reflect the areas of opportunity for improved cost effective techniques for exploration and production of oil and gas in the North Sea and worldwide. The book is indispensable for engineers and scientists interested in the latest advances in technology and resource management that will reduce costs and continue to enhance the safe exploration of oil and gas resources. This volume comprises a selection of contributions presented at the International Conference Subsea International '93, held 28--29 April 1993 in Aberdeen, U.K.
Contaminated sediments pose some of the most difficult site remediation issues. Contaminated sediments typically reside in spatially variable and dynamic systems subject to seasonal flow variations and episodic storm events. The volume of sediments that must be managed at particular sites often exceeds one million cubic meters, dwarfing many contaminated soil sites. These sediments are also associated with equally daunting volumes of water and efforts to remove the contamination typically entrains even more water. The environmental security of both NATO and partner countries is at risk due to the pervasive nature of sediment contamination of rivers, lakes and harbors. A NATO Advanced Research Workshop was convened in Bratislava in May 2005 to discuss current approaches to managing contaminated sediments and to identify research necessary to overcome outstanding problems. In this text, drawn from presentations and discussion of that workshop, current approaches to the assessment and remediation of contaminated sediments will be discussed with the emphasis on in-situ management. Physical, chemical and biological approaches for the assessment and remediation of sediments are all addressed. Developing regulatory and strategic approaches are highlighted with a special emphasis on the potential for biological remediation for the management of contaminated sediments.
A growing proportion of the world's population is dependent on Seawater Desalination as a source of fresh water for both potable and civil use. One of the main drawbacks of conventional desalination technologies is the substantial energy requirement, which is facing cost increases in the global energy market. "Seawater Desalination" presents an overview of conventional and non-conventional technologies, with a particular focus on the coupling of renewable energies with desalination processes. The first section of this book presents, in a technical but reader-friendly way, an overview of currently-used desalination processes, from thermal to membrane processes, highlighting the relevant technical features, advantages and disadvantages, and development potential. It also gives a rapid insight into the economic aspects of fresh water production from seawater. The second section of the book presents novel processes which use Renewable Energies for fresh water production. From the first solar still evaporators, which artificially reproduced the natural cycle of water, technology has progressed to develop complex systems to harness energy from the sun, wind, tides, waves, etc. and then to use this energy to power conventional or novel desalination processes. Most of these processes are still at a preliminary stage of development, but some are already being cited as examples in remote areas, where they are proving to be valuable in solving the problems of water scarcity. A rapid growth in these technologies is foreseen in the coming years. This book provides a unique foundation, within the context of present and future sustainability, for professionals, technicians, managers, and private and public institutions operating in the area of fresh water supply.

Grounded in the user-centered design movement, this book offers a broad consideration of how our civilization has evolved its technical infrastructure for human purpose to help us make sense of the contemporary world of information infrastructure and online existence. The author incorporates historical, cultural and aesthetic approaches to situating information and its underlying technologies across time in the collective, lived experiences of humanity. In today's digital information world, user experience is vital to the success of any product or service. Yet as the user population expands to include us all, designing for people who vary in skills, abilities, preferences and backgrounds is challenging. This book provides an integrated understanding of users, and the methods that have evolved to identify usability challenges, that can facilitate cohesive and earlier solutions. The book treats information creation and use as a core human behavior based on acts of representation and recording that humans have always practiced. It suggests that the traditional ways of studying information use, with their origins in the distinct layers of social science theories and models is limiting our understanding of what it means to be an information user and hampers our efforts at being truly user-centric in design. Instead, the book offers a way of integrating the knowledge base to support a richer view of use and users in design education and evaluation. Understanding Users is aimed at those studying or practicing user-centered design and anyone interested in learning how people might be better integrated in the design of new technologies to augment human capabilities and experiences.
In determining the response of offshore structures, it is of utmost importance to determine, in the most correct manner, all factors which contribute to the total force acting on these structures. Applying the Morison formula (Morison et. al. , 1950) to calculate forces on offshore slender structures, uncertainties related to the understanding of the wave climate, the hydrodynamic force coefficients and the kinematics of ocean waves represent the most important contributions to the uncertainties in the prediction of the total forces on these structures (Haver and Gudmestad, 1992). Traditional calculation of forces on offshore structures involves the use of regular waves with the following non-linearities inco1porated use of regular wave theories inco1porating higher order terms use of Morison equation having a nonlinear drag term inclusion of the effect of the free surface by integrating all contributions to total forces and moments from the sea floor to the free surface of the waves In order to describe the sea more realistically, the ocean surface is to be described as an irregular sea surface represented by its energy spectrum. The associated decomposition of the sea surface is given as a linear sum of linear waves. The total force is found by integrating the contribution from all components in the wave spectrum to the free surface. The kinematics of each component must therefore be determined.

The book is suitable as a textbook for senior-level undergraduate and graduate students as well as a reference for practicing engineers and researchers. The field of application of the book is very broad and diverse and covers areas such as hydroelectric projects, pumped storage schemes, water-supply systems, cooling-water systems, oil pipelines and industrial piping systems. A strong emphasis is given to practical applications: several case studies, problems of applied nature, and design criteria are included. This will help the design engineers and introduce the students to real-life projects. Up-to-date references are included at the end of each chapter.
Product design is becoming increasingly challenging as product complexity increases dramatically with the advent of autonomous control and the need to achieve zero emissions. Companies continue to have poor product launches with significant numbers of recall campaigns and high after-sales warranties. It is important that potential product failures are identified and fixed during the design of a product. Failure modes found late after the design has matured are normally easy to find with some being identified by the customer but are often difficult and expensive to fix since modifying one part will often have a knock-on effect on other parts causing other problems. Discovering failure modes early in the design process is often difficult requiring rigorous and comprehensive analysis but once found such failure modes are usually easy and cheap to fix. This book presents an approach to product design based on Failure Mode Avoidance that utilizes a series of strongly interrelated engineering tools and interpersonal skills that can be used to discover failure modes early in the design process. The tools can be used across engineering disciplines. Despite engineering being largely a team activity, it is often the case that little attention is paid to the team process after the team membership has been identified, with membership normally being based on technical expertise. In addition to technical expertise, an effective engineering team requires individual engineers to work together efficiently. Good leadership is also required with the leader able to both manage change and encourage individual team members to work to the best of their ability. The book interweaves technical skills, team skills, and team leadership in a way that reflects their real-life interrelationship. The book tells the fictional story of a small engineering team and its leader as they implement the skills introduced in the book and follows their experiences reflecting individual difficulties, enthusiasm, humor, and skepticism in applying the methodologies and tools for the first time. In addition, the story tells of team members' interactions with their management and peers within a company that, having been very successful, finds itself in financial difficulties. It promotes constructivist learning through the reader empathizing with the characters in the book. These characters ask questions that are typical of those that learners will ask about the subject matter. Learning reinforcement is also integrated into the storyline as a natural and unobtrusive feature. The book is intended to be read like a novel from cover to cover with a storyline that motivates the reader to read on. While including in-depth technical examples the book is not intended as a seminal text on Failure Mode Avoidance or team skills but is intended to give the reader an understanding such that they are motivated to learn more. Having read the book, it can be treated more typically as a textbook by returning to some of the technical detail or looking to further reading such as that identified in the book.
