Excess water in the urban environment results in flooding, which causes structural damage, risks to personal safety and disruption to city life. Water is also a major contributory factor for disease transmission as well as being the medium for transport of many pollutants. These problems are of increasing concern due to climate changes and are particularly apparent in the humid tropics. Integrated Urban Water Management in the Humid Tropics ? the output of a project by UNESCO's International Hydrological Programme on the topic ? focuses on engineering aspects related to water supply, wastewater and stormwater management in the humid tropics. Flood control is dealt with a specific emphasis on reducing vulnerability to flood disasters in urban areas.The book also addresses environmental health concerns related to the different components of the urban water system and strategies for their control. The volume provides illustrations of different aspects of integrated water management in the urban environment by drawing upon a set of case studies ? predominantly from South America.

Every day throughout Britain, by road, by rail and by sea, there are large numbers of routine movements of radioactive cargo. Materials at all stages of the nuclear cycle, from uranium ore to nuclear waste, from nuclear warheads to radioactive isotopes used in medicine, are constantly on the move. In normal circumstances handling low-level material exposes workers to small doses of radiation, but a serious accident could lead to widespread contamination and to the major risk of additional deaths from cancer. The accident record is not good. There are repeated small accidents and many people believe that the major accident is simply waiting to happen. This book gives a thorough account of what is moved, by wham and far what purpose. It considers the risks, including that of terrorism, the safety record and the precautions. It also highlights the perils of the secrecy surrounding the industry: for example, local councils are responsible for coping with any accident, but are not told when or where nuclear movements are taking place. Martin Bond's careful work is a large step towards order in a chaotic industry. Originally published in 1992

'This book bridges disciplines, previously confined to specialist journal publications, by providing a comprehensive overview of the systems analysis application to water resources. It is ideal for Masters-level courses in Water Resources Engineering where modern management techniques of optimization and modelling are highly important in the strategic management of a vital resource.' - Derek Clarke, University of Southampton, UK 'The great novelty of this book is that it presents in detail how fuzzy-set theory can be used in water resource system management. The author was one of the pioneers who opened up this new field and is considered to be one of the greatest experts in it.' - Rodolfo Soncini Sessa, Politecnico di Milano, Italy Water resources management is increasingly interdisciplinary and must take into account complex socioeconomic factors and environmental variables. This book describes the 'systems approach' and its application to contemporary water resources management, focusing on three main sets of tools: simulation, optimization and multi-objective analysis. This approach is presented within the context of sustainable planning and development under conditions of uncertainty. Managing Water Resources: Methods and Tools for a Systems Approach introduces system dynamic simulation as a tool for integrated modelling and contains coverage of the use of fuzzy sets for incorporating objective and subjective uncertainties. The book combines theory with many practical examples, as well as including programs and exercises on downloadable resources. It comprises both an advanced text for students of water resources and civil or environmental engineering and a practical guide for professionals. Published jointly with UNESCO and International Hydrological Programme

Deliberately, accidentally, or consequentially, first responders and waste site workers handle unknown substances of varying degrees of danger every day. Unidentified chemicals involved with clandestine production of WMD agents or drugs, explosive materials, unlabeled waste, and forensic samples all pose a threat to the worker and those they protect. A straightforward, concise handbook of practical strategies is needed to perform effective risk assessment and management in the face of uncertainty. Written for emergency workers responsible for the safe response to and management of unknown hazardous materials, Emergency Characterization of Unknown Materials providesreadily applicable strategies for developing and implementing a fluid concept of risk analysis based on hazard characterization in emergency situations where definitive identification of the material may be impractical or even impossible. Using a hands-on approach involving the manipulation of small amounts of material, the author discusses strategies to identify threats and vulnerabilities, ascertain exposure, and reduce or eliminate impact. The book begins with an overview of chemical and physical terms and definitions. It continues with a look at types of hazards presented by chemical compounds and mixtures, organisms, and radiation sources. It covers approximately 63 portable technologies for field identification or characterization and examines general technological advantages and disadvantages relative to hazard identification. The final chapter presents strategies for use in identifying or characterizing suspected weapons of mass destruction, illegal drugs, explosive substances, biological hazards, and other hazardous materials. Each chapter includes extensive references and a comprehensive index. Providing a sweeping overview of hazards and emphasizing risk analysis and public safety, Emergency Characterization of Unknown Materials gives first responders an advantage they deserve.

Groundwater is the most important source of domestic, industrial, and agricultural water and also a finite resource. Population growth has created an unprecedented demand for water, with the situation most critical in the developing world, where several million people depend on contaminated groundwater for drinking purposes. Geogenic contaminants, such as arsenic and fluoride at toxic levels, pose major environmental risks and endanger public health. This book is a collection of papers providing a multi-disciplinary overview for scientists and professionals involved in the sustainable development of groundwater resources.

This volume describes various scenarios of conflict and cooperation over water resources among stakeholders in a variety of settings. It discusses treaty making over international rivers, bilateral cooperation on river development between South Africa and Lesotho, the political economy of water supply in the Pacific Island region, the establishment of the Mekong River Commission in Southeast Asia, comparative river basin management in the United States and South Korea, and the International Joint Commission formed by Canada and the United States to resolve boundary water conflicts. The book also explores national domestic conflicts over water resources in Bangladesh and China, Cold War hydropolitics in Southern Africa, water management conflicts in the Niger River Basin of West Africa, and water as commodity and source of conflict in Australia.

Except in schoolboy jokes, the subject of human waste is rarely aired. We talk about water-related diseases when most are sanitation-related - in short, we don t mention the shit.A century and a half ago, a long, hot summer reduced the Thames flowing past the UK Houses of Parliament to a Great Stink, thereby inducing MPs to legislate sanitary reform. Today, another sanitary reformation is needed, one that manages to spread cheaper and simpler systems to people everywhere.In the byways of the developing world, much is quietly happening on the excretory frontier. In 2008, the International Year of Sanitation, the authors bring this awkward subject to a wider audience than the world of international filth usually commands. They seek the elimination of the Great Distaste so that people without political clout or economic muscle can claim their right to a dignified and hygienic place to go .Published with UNICEF

Few policy areas in recent history have the attention of the Australian public and polity as much as those relating to water. Water Policy in Australia considers the current policy reform agenda from agricultural, environmental, and cultural perspectives. It presents a comprehensive account of the country's critical water issues and provides expert perspectives from behavioral and institutional economists, engineers, hydrologists, sociologists, and water law specialists. norms, and values relating to the exploitation of water resources. Until the 1980s, the engineer was king, and policymakers viewed water as an endless resource for driving economic growth. However, in the last twenty years, policymakers have been forced to acknowledge that it is not possible to perpetually supply more water at a low cost. Consequently, the country has begun to focus on water resource management through legislative and institutional change - attempting to allocate water in a more economically efficient and socially and environmentally acceptable manner. institutional change, as well as valuable lessons on the design of property rights for complex resources. The editor and contributors look beyond recent reform efforts and address the hydrological, biophysical, economic, and social factors at play in Australia. The book addresses pertinent issues, such as irrigation in the Murray-Darling basin, one of Australia's largest drainage divisions; the progression from common law riparian rights to share-based entitlements that encourage sustainable water use; and the potential outcomes of the recent National Water Initiative, a wide-ranging strategy to improve water management and simultaneously maintain healthy groundwater and river systems.

During the past three decades, urban groundwater has emerged as one of the world's most pressing issues. Explosive population growth, most prevalent in cities, has placed an inordinate demand on groundwater supply, prompting concerns for its long-term sustainability at a time when the quality of available groundwater resources is being increasingly degraded by anthropogenic activity. Cities less reliant on groundwater for potable supply are equally obliged to manage subsurface water with cautious respect since rising groundwater levels can generate a myriad of problems such as unstable land slopes, flooded basements, tunnels and electrical utilities, and the release of polluted water to urban wetlands, springs and streams.Challenges in Urban Groundwater is premised on a growing recognition that most urban groundwater problems are not uniquely associated with any particular region or hydrogeological environment, and much can be learned by understanding the successes and failures of others. It showcases the best urban groundwater papers presented at the International Geological Congress held in Florence, Italy in 2004, and is supplemented by contributions solicited from other world experts active in urban groundwater research. Topics covered range from the urban water balance and rising groundwater levels to groundwater contamination and the role of aquifer modelling.

Increasing demand on industrial capacity has, as an unintended consequence, produced an accompanying increase in harmful and hazardous wastes. Derived from the second edition of the popular Handbook of Industrial and Hazardous Wastes Treatment, Hazardous Industrial Waste Treatment outlines the fundamentals and latest developments in hazardous waste treatment in various process industries, such as metal finishing, photographic processing, wood treatment, and explosives. Comprehensive in scope, the book provides information that is directly applicable to daily waste management problems throughout the industry. The book contains in-depth discussions of environmental pollution sources, waste characteristics, control technologies, management strategies, facility innovations, process alternatives, costs, case histories, effluent standards, and future trends for the process industry. It includes extensive bibliographies for each type of industrial process waste treatment or practice, invaluable information to anyone who needs to trace, follow, duplicate, or improve on a specific process waste treatment practice. A quick scan of the chapters and contributors reveals the depth and breadth of the book's coverage. Hazardous Industrial Waste Treatment provides technical and economical information on how to develop the most feasible total environmental control program that can benefit both industry and local municipalities.

The management of, and access to, water resources have been universally identified as a key aspect of poverty reduction, agriculture and food security and sustainable development in developing, transitional, and developed countries worldwide. Yet good "water governance," so eagerly sought, has in practice proven difficult to achieve. This book, edited and authored by leading authorities on water resource management, examines the recent changes in governance, institutions, economics, and policies of water, from a global point of view and a cross-country perspective, with special emphasis on African and Southern African case studies.The authors show that in recent years, water policies, institutions, and governance have shifted from technical, quantitative, supply-driven, centrally controlled management to more demand-sensitive, qualitative, decentralized, participatory, integrated approaches. Such a move also often supposes cost recovery principles, resource allocation among competing sectors, and privatization. In most developing countries, motivations for these changes have been increased resource scarcity, increased diversity of users and uses, urbanization, financial constraints and the need for sustainable development through renewed water management. Yet the creation and operation of new policies and legal frameworks often fall short of initial expectations since management transfer and decentralization processes, cost recovery principles and the emergence of new local organizations have proven difficult to implement. The book examines these issues through case studies at national, river basin, and local levels using accessible multidisciplinary approaches that integrate economics, institutional analysis, geography, and policy analysis. Ultimately the book untangles and presents best practices for policy and decision makers, governments and regulators, NGOs and user groups, farmers, water-supply companies, and researchers, and points towards how good water governance structures can be developed and implemented for the benefit of all.

The unit process approach, common in the field of chemical engineering, was introduced about 1962 to the field of environmental engineering. An understanding of unit processes is the foundation for continued learning and for designing treatment systems. The time is ripe for a new textbook that delineates the role of unit process principles in environmental engineering. Suitable for a two-semester course, Water Treatment Unit Processes: Physical and Chemical provides the grounding in the underlying principles of each unit process that students need in order to link theory to practice. Bridging the gap between scientific principles and engineering practice, the book covers approaches that are common to all unit processes as well as principles that characterize each unit process. Integrating theory into algorithms for practice, Professor Hendricks emphasizes the fundamentals, using simple explanations and avoiding models that are too complex mathematically, allowing students to assimilate principles without getting sidelined by excess calculations. Applications of unit processes principles are illustrated by example problems in each chapter. Student problems are provided at the end of each chapter; the solutions manual can be downloaded from the CRC Press Web site. Excel spreadsheets are integrated into the text as tables designated by a "CD" prefix. Certain spreadsheets illustrate the idea of "scenarios" that emphasize the idea that design solutions depend upon assumptions and the interactions between design variables. The spreadsheets can be downloaded from the CRC web site. The book has been designed so that each unit process topic is self-contained, with sidebars and examples throughout the text. Each chapter has subheadings, so that students can scan the pages and identify important topics with little effort. Problems, references, and a glossary are found at the end of each chapter. Most chapters contain downloadable Excel spreadsheets integrated into the text and appendices with additional information. Appendices at the end of the book provide useful reference material on various topics that support the text. This design allows students at different levels to easily navigate through the book and professors to assign pertinent sections in the order they prefer. The book gives your students an understanding of the broader aspects of one of the core areas of the environmental engineering curriculum and knowledge important for the design of treatment systems.

Solid Waste Landfilling: Concepts, Processes, Technology provides information on technologies that promote stabilization and minimize environmental impacts in landfills. As the main challenges in waste management are the reduction and proper treatment of waste and the appropriate use of waste streams, the book satisfies the needs of a modern landfill, covering waste pre-treatment, in situ treatment, long-term behavior, closure, aftercare, environmental impact and sustainability. It is written for practitioners who need specific information on landfill construction and operation, but is also ideal for those concerned about the possible return of these sites to landscapes and their subsequent uses for future generations.

In the 20th century, water management focused on the local scale of interest. In the 21st century we will be facing changes in quantity and quality of our water cycle. Triggering forces behind these new challenges are industrialisation, population growth and the delayed awareness that we are to expect a global change. The magnitude and distribution of global changes are not exactly predictable, because we live in an always changing environment, are faced with severe and interfering processes, which all are not yet sufficiently understood. Therefore, to shoulder this task, hydrology should embrace more integrative and interdisciplinary approaches than already existing and has to achieve more flexibility in assessments and decisions. To better approach this challenge, catchments related solutions are more important than local solutions, to satisfy the water demand of agriculture, ecosystems, industry and the private sector. And we should keep in mind that the environment has a "sustainable memory" and our knowledge about attenuation capacities and resilience of the environment is still low.

There are approximately 50,000 small water supplies in the UK alone, and thousands more worldwide. Dealing with the idiosyncratic characteristics of small water supplies requires specialist knowledge, and this book provides invaluable guidance for professionals.

Based on the extensive practical experience of the author, this book covers how small independent supplies differ from public water supplies, and outlines the health dangers they pose, along with detailed instruction in water sampling and risk assessment techniques. Clapham describes the different types of water supplies including their construction and treatment systems, and discusses common problems encountered. A wide range of case studies bring the theory to life, and both UK and European legislation is discussed. There is also a sizeable section dealing with small water supplies in developing countries.

In the countries of the Middle East and Northern Africa, reclaimed wastewater is recognized as a non-conventional water resource. However, substandial amounts are still discharged into water courses without further treatment. The objective of this research was to analyse the technological, regulatory, institutional, financial and socio-cultural opportunities, seen as incentives; and the constraints, perceived as disincentives, which influence the adoption of wastewater treatment and reuse. Fieldwork was carried out in Jordan and Tunisia, countries which have made great strides in raising the proportion of re-used wastewater. Unexpectedly, farmers and customers proved well-prepared to use reclaimed water in irrigation, and to buy crops raised in the irrigated fields. Abu-Madi stresses the need for raising the price of freshwater, reflecting its true scarcity, thus creating a stronger incentive to utilise reclaimed wastewater.

The protection of groundwater and surface water from contamination by the escape of contaminant from waste disposal is now an important consideration in many countries of the world.
This book deals with the design of "barrier systems"which separate waste from the surrounding environment and which are intended to prevent contamination of both groundwater and surface waters. The authors discuss all key aspects of the design of barrier systems, including leachate collection, natural barriers such as clayey aquitards, clay liners, geomembrane and composite liners, providing a state-of-the-art work of reference of great value to engineers and environmentalists alike. This retitled second edition of "Clayey Barrier Systems for Waste Disposal" has been fully revised and updated, with new chapters on geomembranes and geosynthetic clay liners as well as a number of new chapters.
Engineers involved with waste management, geotechnics and landfill design will use this book in order to understand the concepts, find out about the latest developments and subsequently apply them to practical applications relevant to the design of barrier systems.

Encompassing the areas of economics, sociology, social biology and genetics, and drawing on studies from the UK and Australia, this volume charts and analyses the factors affecting population growth. Chapters include: * The international decline in fertility * The changing structure of the family * Educational opportunities * Concepts of race.

Rapid developments in the field precipitated by the increased demand for clean burner systems have rendered much of the published literature outdated. With the Industrial Burners Handbook, best-selling author, editor, and combustion expert Charles Baukal, Jr. fills this gap. This handbook is a comprehensive reference dedicated to the design and applications of industrial burners. In addition to a solid introduction to combustion and burner fundamentals, an outstanding panel of contributing authors address all major burner types and explore a range of topics never before adequately covered in a handbook, including noise, burner controls, and physical modeling.

Hydrometry presents a thorough introduction to the science of hydrometry: the measurement of flow in open channels. Dealing with both traditional techniques and innovative new methods and instruments, in line with the latest ISO standards, this book deals with the main themes of hydrometry: the measurement of water levels and bed levels, of discharge and of sediment transport; it considers the use of flow measuring structures, hydrological networks and the organization of surveys. Dr Boiten has extensive experience of teaching students from many countries and backgrounds, and has distilled this experience into a clear and comprehensive account of hydrology and water resource management. Hydrometry will appeal to graduate students and to professionals engaged in hydrology and the management of water resources.

Little is known about the volume of international recycling in Asia, the problems caused and the struggle to properly manage the trade. This pathbreaking book addresses this gap in the literature, and provides a comprehensive overview of the international trade flow of recyclable waste in Asia and related issues. The expert contributors discuss the various types of recyclable waste that Asian countries import, and illustrate that there are consequently higher numbers of cheaper informal recyclers with lower pollution control costs than formal recyclers with more expensive but environmentally sound technologies. They explore how governments across China, Vietnam, South Korea and Japan are therefore struggling to minimize the negative impact from informal recycling via trade regulation of recyclable and hazardous waste and comprehensive cooperation mechanisms to promote efficient use of resources. Preventive measures against illegal and/or improper transboundary movement of hazardous waste in Asia are also analyzed. This unique and fascinating book aims to facilitate a common understanding of the issues caused by international recycling in Asia to encourage effective international and regional cooperation in order to establish a sound recycling system. As such, it will prove an invaluable resource to academics, researchers and students with an interest in Asian studies, economics, environmental studies, international economics and industrial economics.
