This thesis presents the implementation of fully three-dimensional sediment transport and morphological updating formulations within a proven three-dimensional hydrodynamic flow solver. The thesis briefly discusses the formulations used to model both suspended and bed-load transport of non-cohesive sediment, and describes the implementation of a morphological updating scheme which incorporates novel approaches to morphological acceleration and dry bank erosion. Approaches used to model the three-dimensional effects of waves on coastal hydrodynamics and of three-dimensional currents on waves are also discussed. Results of several validation studies are presented and the model is shown to perform well in a series of simplified theoretical, laboratory, and full scale test cases. Application of the model and acceleration techniques to the complex and dynamic entrance to Willapa Bay, WA, USA is also discussed. Model processes are validated against the results of an extensive field measurement campaign, and diagnostic morphological model simulations are performed for two historical periods of contrasting morphological development. Input reduction and morphological acceleration techniques used to perform 5-year simulations of Willapa Bay are critically analysed and a new generic method to select a representative morphological tide for coastal environments containing significant diurnal tidal energy is presented.

International concern in scientific, industrial, and governmental communi ties over traces of xenobiotics in foods and in both abiotic and biotic envi ronments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published research papers and progress reports, and archival documentations. These three international publications are integrated and scheduled to provide the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamination and toxicology. This series is reserved ex clusively for the diversified literature on "toxic" chemicals in our food, our feeds, our homes, recreational and working surroundings, our domestic animals, our wildlife and ourselves. Tremendous efforts worldwide have been mobilized to evaluate the nature, presence, magnitude, fate, and toxi cology of the chemicals loosed upon the earth. Among the sequelae of this broad new emphasis is an undeniable need for an articulated set of authoritative publications, where one can find the latest important world literature produced by these emerging areas of science together with docu mentation of pertinent ancillary legislation. Research directors and legislative or administrative advisers do not have the time to scan the escalating number of technical publications that may contain articles important to current responsibility. Rather, these individu als need the background provided by detailed reviews and the assurance that the latest information is made available to them, all with minimal literature searching."

In this work, several modelling approaches are explored to represent spatial pattern dynamics of aquatic populations in aquatic ecosystems by the combination of models, knowledge and data in different scales.

It is shown that including spatially distributed inputs retrieved from Remote Sensing images, a conventional physically-based Harmful Algal Bloom model can be enhanced. Also, Cellular Automata based models using high resolution photographs prove to be good in representing aquatic plant growth. Multi-Agent Systems can capture well the spatial patterns exhibited in GIS density maps. A synthesis modelling framework was developed to include biological/ecological growth and diffusive processes, and local effects in conventional modelling framework. The results of the complementary modelling paradigms investigated in this research can be of help in achieving a sustainable environmental management strategy.

The need to produce food without the destructive chemical horrors of much modern farming, for an intelligent use of dwindling natural resources and for humane forms of production is universal, the practice is limited. This book is an account of one, large, instance of success in practice. Twenty-five years ago, Winin Pereira, a nuclear physicist abandoned academia to start a co-operative farm at Alonde in a tribal area north of Bombay. The group experienced, and finally discarded, all the false hopes and promises of Western originated forms of development: ploughs that ploughed too deep, irrigation systems that lowered water tables, fertilizers and pesticides which managed the earth and became so expensive that poorer farmers were dispossessed. Instead they learnt from the adivasai, or tribal people, who have nurtured or been nurtured by foresets for millennia, ways of applying popular knowledge to contemporary problems. This book is a combination of Pereira's record of achievement of sustainable livelihoods and an account of the farm and its effect on the India around it by a leading British journalist.

The destruction of the tropical forest is one of the major problems of our time. Vast areas are rapidly becoming wastelands which support only a few tough weeds, perhaps some cattle, and the farms allowed to the poor. This book provides a vision of hope: in Latin America. Africa. And South East Asia, growing numbers of people are developing techniques specifically designed to promote the wise use and preservation of remaining forest lands. However, these grassroots strategies are often ignored in favour of grandiose schemes which inevitably fail. This pattern must be broken now or the tropical forests will be lost forever.

Modeling Remaining Useful Life Dynamics in Reliability Engineering applies traditional reliability engineering methods to Prognostics and Health Management (PHM), looking at Remaining Useful Life (RUL) and predictive maintenance to enable engineers to effectively and safely predict machinery lifespan. One of the key tools used in defining and implementing predictive maintenance policies is the RUL indicator. However, it is essential to account for the uncertainty inherent to the RUL, as otherwise predictive maintenance strategies can be incorrect. This can cause high costs, or alternatively, ineffective predictions. Methods used to estimate RUL are very numerous and diverse, and broadly speaking, fall into three categories: model-based, data-driven, or hybrid, which uses both. The book starts by building on established theory, and applying cutting edge research to it, such as artificial intelligence models and deep learning. It looks at traditional reliability engineering methods through their relation to Prognostics and Health Management (PHM) requirements and presents the concept of RUL loss rate. Following on from this, the book presents a general method for defining a nonlinear transformation enabling the MRL to become a linear function. It also touches on topics such as Weibull distribution, gamma distribution and degradation, along with time-to-failure distributions. Features: Provides both practical and theoretical background of RUL Describes how the uncertainty of RUL can be related to RUL loss rate Provides new insights into time-to-failure distributions Offers tools for predictive maintenance_ The book will be of interest to engineers and researchers in reliability engineering, Prognostics and Health Management and industry management.

Don't drain the swamp! Man's traditional response to swamps, marshes and bogs has been to drain them. But wetlands are not wastelands. Coastal marshes are among the world's most productive ecosystems. They make many commercial fisheries possible and protect coasts from floods and storm surges. Wetlands are pollution filters, water reservoirs. They are among the last wild places on earth, offering homes to endangered plants, birds and animals. Attitudes to wetlands are changing, but not fast enough. As scientists are documenting the wealth in wet places, governments and developers are draining them, damming them, logging them and building resort hotels where ', they once were. Destruction is usually a poor trade-off: well-managed wetlands in Louisiana are producing fortunes in seafood and timber. Waterlogged wealth examines the value of swamps and marshes, as well as the threats against them. In doing so it takes the reader to some of the world's most bizarre landscapes: the 'inland delta' of the Niger River in drought-stricken Mali; the wildlife-rich Okavango swamps of Botswana; the waterlogged Sunderban forests of India and Bangladesh, where tigers eat fish and crabs. Civilisation began around wetlands; today's civilisation has good reason to leave them wet and wild. Dr Edward Maltby is a lecturer in geography at the University of Exeter(UK). He has done extensive research on wetlands both in the North (UK, US, Canada) and the South (Fiji, Jamaica, India and the Falklands/Malvinas Islands). He is on the IUCN Wetland Programme Advisory Committee. Originally published in 1986

This richly-illustrated reference guide presents innovative techniques focused on reducing time, cost and risk in the construction and maintenance of underground facilities:

A primary focus of the technological development in underground engineering is to ease the practical execution and to reduce time, cost and risk in the construction and maintenance of underground facilities such as tunnels and caverns. This can be realized by new design tools for designers, by instant data access for engineers, by virtual prototyping and training for manufacturers, and by robotic devices for maintenance and repair for operators and many more advances.

This volume presents the latest technological innovations in underground design, construction, and operation, and comprehensively discusses developments in ground improvement, simulation, process integration, safety, monitoring, environmental impact, equipment, boring and cutting, personnel training, materials, robotics and more. These new features are the result of a big research project on underground engineering, which has involved many players in the discipline.

Written in an accessible style and with a focus on applied engineering, this book is aimed at a readership of engineers, consultants, contractors, operators, researchers, manufacturers, suppliers and clients in the underground engineering business. It may moreover be used as educational material for advanced courses in tunnelling and underground construction.

This volume presents research on current trends in chemical regulations - a fa- growing, complex, and increasingly internationalized field. The book grew out from a multidisciplinary research project entitled 'Regulating Chemical Risks in the Baltic Sea Area: Science, Politics, and the Media', led by Michael Gilek at Soedertoern University, Sweden. This research project involved scholars and experts from natural as well as social sciences, based at Soedertoern University, Swedish Royal Institute of Technology (KTH), Karolinska Institutet, and Umea University. The project group organized a multidisciplinary research conference on chemical risk regulations, held in Stockholm, August 15-17, 2007. Most of the contributions published in this book were, in draft form, first presented at this conference. The conference, like the ensuing edited volume, expanded the geographical focus beyond the Baltic Sea area to include wider European, and to some extent also global trends. Many thanks to all project colleagues and conference participants! We are very grateful for the generous financial support received from The Foundation for Baltic and East European Studies (OEstersjoestiftelsen), The Swedish Research Council Formas, and from Soedertoern University. Without this support the present book would not have been possible. Special thanks to all of our fellow contributors, all of whom have submitted to- cal papers based on high-quality research. Many thanks also to Tobias Evers, who assisted us with technical editing. Finally, we are grateful for the professionalism shown by our editors at Springer.

The Brazilian Amazon is the largest area of tropical rainforest in Latin America. Brazil is that continent's most rapidly developing country. The Amazon is at the heart of the conflict between conservation and development, between people and power, and between heritage and modernisation. In the name of development, the powerful are colonizing the forest. The greatest new threat comes from the massive hydro-electric schemes which are being pushed ahead with little regard to efficacy, the rights of the people, or the survival of the forest. Dam the Rivers, Damn the People is about two of the most affected areas, Balbina in Amazonas and the Xingu River in Para. Barbara Cummings describes the plans which the state attempted to keep secret, the extent to which these projects will destroy the forest, the consequent dispossession of the people of the forest and, above all, their growing resistance. She shows how the outcome of their fight affects us all. Originally published in 1990

Tomatoes could not be grown commercially without the help of their wild relatives. A single wild species of rice has helped double rice production in Asia. Wild silk-worms are enabling India to expand its silk industry. A wild carp with resistance to cold has been used to extend Soviet carp production further into the north. Wild genetic resources - the heritable characteristics of wild plants and animals - are used increasingly to improve domesticated crops and livestock and as new sources of food and of raw materials. But habitat destruction, over-exploitation and competition from introduced species is destroying many gene pools even before they have been identified. Genes from the Wild describes the growing contribution of wild genetic resources to the production of food and raw materials, describes their characteristics, explains the benefits and problems of using them and outlines the ways in which they are threatened and the measures being taken to conserve them.

The changing climate, the warming of the world and acid rain are among the greatest problems facing us at the end of the twentieth century. This book describes, for the first time, the effects of these phenomena on the high mountains and the forests of Europe. Mountains and the frozen regions (the cryosphere) not only play a major part in our climatic system, but are also central to our water supplies. Yet our glaciers are shrinking, our lakes and soils are becoming acidified, our forests are damaged and the whole fragile ecosystem of ranges like the Alps and the Caucasus is threatened. Nilsson and Pitt present the evidence and assess the probable effects of these changes on mountain society, tourism, water, flora and fauna. They also examine the uncertainties. Above all they look, too, at the best possible strategies in response to What is happening and at what the next steps should be. Originally published in 1991

Lands lost to desert may effectively be lost for ever, so desertification is humanity's most obvious despoliation to the planet. It is certainly one of the most serious environmental problems facing the world today. In this book the author describes what is happening and where. Although the problem is greatest in developing countries, it is by no means confined to them. Australia, Africa, the USA and India are all affected. In the 1970s an international Plan of Action was drawn up to bring the phenomenon under control, but it was never implemented. Now that the situation is more serious than ever before, this book urges new action and describes many of the myriad ways in which it is possible to arrest the progress of desertification. It describes, too, not just the failures, but the considerable successes that have been achieved. Originally published in 1990

In 1990, energy in the UK underwent a unique and fundamental transformation, with the privatization of the electricity supply industry. This is the first book to fully assess the experiment. It first explains how - and why - the British electricity supply industry was privatized. It then identifies the subsequent changes in electricity prices, profits, employment, investment, nuclear power and renewable, and the extent to which each of these was due solely to privatization or to other factors, or could have come about by reform of the previous model, rather than privatization. Finally, the authors analyse the key unresolved issues of regulation, introducing competition into the domestic energy market in 1998, supply security, and other long-term strategic considerations. Throughout, the distinguish between the uniquely British elements of the experience and those which can be drawn upon by other countries embarking upon similar reforms. Today, governments throughout the world are looking to the UK's experience as a potential prototype for the restructure of their own electricity supply industries. For them, and for electricity utilities, fuel and power plant suppliers, regulation authorities, financial analysts, international agencies, journalists and academics alike, this thorough and pragmatic study will be essential reading. 'This is likely to become the definitive book on the first six years of the great British electricity experiment' Walt Patterson The British Electricity Experiment is the result of a detailed study undertaken by the Energy Programme at the science Policy Research unit (SPRU). Professor John Surrey was head of SPR's Energy Programme between 1969 and 1986. He has worked with the central Electricity Generating Board, as a government Economic Adviser, and as a Specialist Adviser to numerous House of Commons Select Committee inquiries on energy matters.

Most of the world's population lives on or near the coasts. Every nation not completely landlocked has used the sea as its supposedly self-cleansing garbage dump. Now the effects are being felt. There is not a coast in the world which is not dangerously polluted. Sewage, oil, plastics, industrial effluents, radioactive waste have been added to ungoverned development, all of which are busily destroying otherwise robust inshore eco-systems. Hinrichsen, basing his work on United Nations Environment Programme (UNEP) research and his own extensive travels, has described the situation in the Mediterranean, the Gulf, the Indian Ocean, the South-East Asian Seas and the Eastern Pacific. He covers both the disasters and the growing successes in dealing with them, and he points the way to the sort of international deal needed to rescue a vast resource in danger of complete destruction. His book is both a call to action and a sign of hope.Originally published in 1990

Hiroshi Komiyama's "Vision 2050" is a plan for paving a road to global sustainability. It lays out a path to a sustainable future for humanity that could realistically be achieved by 2050 through the application of science and technology. A prominent Japanese academic and leader in global sustainability, Komiyama draws upon realistic assumptions and solid scientific concepts to create a vision that makes the living standards enjoyed by developed countries today possible for all people by 2050. "Vision 2050" is built upon three fundamental principles - increased energy efficiency, recycling, and development of renewable energy sources - and the book argues for the technological potential of all three. Specifically, Komiyama envisions a three-fold increase in overall energy efficiency and a doubling of renewable energy resources by 2050. "Vision 2050: Roadmap for a Sustainable Earth" is written to address the concerned citizen as well as to inspire an exchange of ideas among experts, policy makers, industrial leaders, and the general public.

Why Study Supervision? This book presents two compelling reasons to study supervision and supervisory leadership: Influential Position: Supervisors exert considerable influence on organizational settings. Supervisors have been schooled, developed, and trained for their responsibilities. They can function more effectively than if they learn through informal, sometimes haphazard means. It thus pays to learn about supervision because supervisors can influence how efficiently and effectively their organization functions. Career Path: Many career paths lead to supervision. Supervisors are everywhere. Supervisors are teachers, doctors, accountants, lawyers, plumbers, and electricians. If you aspire to advance within your occupation, you may find that one career path leads to supervision. Preparing for supervisory responsibilities can prepare you for advancement. You may thus have a personal stake – your own future – in learning about what supervisors do and how they do it. In addition, this book: Provides strategies for building solid relationships with team members. Uses positivity as a foundational practice to lead and encourage other employees. Provides guidelines on how to hold employees accountable and set high expectations. Presents strategies to engage, coach, and develop employees by creating a positive environment to influence attitudes and behaviors. Offers various approaches for managing time and increasing productivity.

This monograph provides, for the first time, a most comprehensive statistical account of composite sampling as an ingenious environmental sampling method to help accomplish observational economy in a variety of environmental and ecological studies. Sampling consists of selection, acquisition, and quantification of a part of the population. But often what is desirable is not affordable, and what is affordable is not adequate. How do we deal with this dilemma? Operationally, composite sampling recognizes the distinction between selection, acquisition, and quantification. In certain applications, it is a common experience that the costs of selection and acquisition are not very high, but the cost of quantification, or measurement, is substantially high. In such situations, one may select a sample sufficiently large to satisfy the requirement of representativeness and precision and then, by combining several sampling units into composites, reduce the cost of measurement to an affordable level. Thus composite sampling offers an approach to deal with the classical dilemma of desirable versus affordable sample sizes, when conventional statistical methods fail to resolve the problem. Composite sampling, at least under idealized conditions, incurs no loss of information for estimating the population means. But an important limitation to the method has been the loss of information on individual sample values, such as the extremely large value. In many of the situations where individual sample values are of interest or concern, composite sampling methods can be suitably modified to retrieve the information on individual sample values that may be lost due to compositing. In this monograph, we present statistical solutions to these and other issues that arise in the context of applications of composite sampling. Content Level Research
