Cyanobacterial toxins are among the hazardous substances most widely found in water. They occur naturally, but concentrations hazardous to human health are usually due to human activity. Therefore, to protect human health, managing lakes, reservoirs and rivers to prevent cyanobacterial blooms is critical. This second edition of Toxic Cyanobacteria in Water presents the current state of knowledge on the occurrence of cyanobacteria and cyanotoxins as well as their impacts on health through water-related exposure pathways, chiefly drinking-water and recreational activity. It provides scientific and technical background information to support hazard identification, assessment and prioritisation of the risks posed by cyanotoxins, and it outlines approaches for their management at each step of the water-use system. It sets out key practical considerations for developing management strategies, implementing efficient measures and designing monitoring programmes. This enables stakeholders to evaluate whether there is a health risk from toxic cyanobacteria and to mitigate it with appropriate measures. This book is intended for those working on toxic cyanobacteria with a specific focus on public health protection. It intends to empower professionals from different disciplines to communicate and cooperate for sustainable management of toxic cyanobacteria, including public health workers, ecologists, academics, and catchment and waterbody managers. Ingrid Chorus headed the department for Drinking-Water and Swimming-Pool Hygiene at the German Environment Agency. Martin Welker is a limnologist and microbiologist, currently with bioMerieux in Lyon, France.

It explores the opportunities and challenges of using AgNPs as an antimicrobial agent, and includes the latest research findings. It compares three kinds of AgNPs with regard to their antibacterial and antiviral effects; their sustainability in real water matrices; and their antiviral mechanisms. The outcome of this research equips the water industry with a better understanding of the capacity, extent and mechanisms of nanosilver disinfection. It is of interest to graduate students, academics and researchers in the area of nanotechnology and environmental engineering.

This book integrates 30 years of mercury research in the Florida Everglades to inform scientists and policy makers. The Everglades is an iconic ecosystem by virtue of its expanse; diversity of biota; and multiple international designations. Despite this, the Everglades has been subjected to multiple threats including: habitat loss, hydrologic alterations, invasive species and altered water quality. Less well recognized as a threat to Everglades human use and wildlife populations is the toxic metal, mercury. The first half of Volume II focuses on biogeochemistry and factors unique to the Everglades that make it extraordinarily susceptible to mercury methylation following its deposition: warm subtropical climate, shallow depth, high levels of dissolved organic matter, sulfate contamination, nutrient enrichment and sediment redox conditions (for review of atmospheric mercury deposition significance, see Vol. I). The second half of Volume II answers the "so what" question - why biomagnification of the methylmercury produced in the Everglades is a threat to the health of top predators including humans. The results of the synthesis presented in Volume II suggest that the mercury problem in the Florida Everglades is one of the worst in the world due to its areal extent and the degree of risk to ecological receptors and humans.

This book promotes better understanding and awareness of South Africa' significant water problems by describing the country's and especially the Upper Vaal River's water resources. It is a "go-to" book for students, professionals and regular citizens when information is required regarding the country's and more specifically the Upper Vaal River's freshwater resources. It highlights the major problems and risks which need to be addressed and give a realistic and true representation of the current water affairs.

The growing impacts of economic activities and climate change on the conditions of rivers throughout the world, require a new, integrated approach towards river basin management, an approach that can also cope with an uncertain future. In this volume, leading European scientists and representatives of major stakeholder groups present risk-informed management as this new approach, as developed in the European Commission-funded project RISKBASE. It aims to improve the ecological quality of river basins and thus to sustain the goods and services they provide for the benefit of society. Risk-informed management involves the integrated application of three key-principles:

. Being well informed

. Managing adaptively

. Pursuing a participatory approach

The authors explain and underpin these principles in detail, offer inspiring examples from practice and connect them to the implementation of the European Water Framework Directive (WFD).

This book is intended for scientists, consultants and practitioners concerned about river basins, world-wide, as well as the drafters and implementers of the WFD River Basin Management Plans.

Great blue herons, yellow birches, damselflies, and beavers are among the talismans by which Bill Roorbach uncovers a natural universe along the stream that runs by his house in Farmington, Maine. Populated by an oddball cast of characters to whom Roorbach ("The Professor") and his family might always be considered outsiders, this book chronicles one man's determined effort-occasionally with hilarious results-to follow his stream to its elusive source. Acclaimed essayist and award-winning fiction writer Bill Roorbach uses his singular literary gifts to inspire us to laugh, love, and experience the wonder of living side by side with the natural world.

This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

Blending memoir, travelogue and history, The Seine is a love letter to Paris and the river that determined its destiny. Master storyteller and The New York Times foreign correspondent Elaine Sciolino explores the Seine through its lively characters-a bargewoman, a riverbank book- seller, a houseboat dweller, a famous cinematographer-and follows it from the remote plateaus of Burgundy, through Paris and to the sea. The Seine is a vivid, enchanting portrait of the world's most irresistible river.

This book, first published in 1984, has both a geomorphic and a hydrologic message. It examines and analyses the role of groundwater in landscapes in a series of articles by authors of diverse backgrounds and experience.

This is an invitation to readers to ponder universal questions about human relations with rivers and water for the precarious times of the Anthropocene. The book asks how humans can learn through sensory embodied encounters with local waterways that shape the architecture of cities and make global connections with environments everywhere. The book considers human becomings with urban waterways to address some of the major conceptual challenges of the Anthropocene, through stories of trauma and healing, environmental activism, and encounters with the living beings that inhabit waterways. Its unique contribution is to bring together Australian Aboriginal knowledges with contemporary western, new materialist, posthuman and Deleuzean philosophies, foregrounding how visual, creative and artistic forms can assist us in thinking beyond the constraints of western thought to enable other modes of being and knowing the world for an unpredictable future. Riverlands of the Anthropocene will be of particular interest to those studying the Anthropocene through the lenses of environmental humanities, environmental education, philosophy, ecofeminism and cultural studies.

Since its establishment as a policy research institute in 1990, the Institute for In- grated Development Studies (IIDS) has been engaged in promoting public awa- ness and understanding of issues of national importance by undertaking studies and research on contemporary themes. It has been disseminating findings of its studies to policymakers in the public and private sectors and ultimately to the public at large. Water resources is one of the areas of strong public interest in Nepal. It is cons- ered a potent engine of economic growth. Its optimal use is dependent on, among other things, the cooperation among the riparian countries, especially India and Bangladesh. Water resources development is one of the subjects in which the Ins- tute has been engaged since its beginning by undertaking studies through national professionals and joint studies on the water resources of the Ganges, Brahmaputra and Meghna river basins with policy research institutes from India and Bangladesh. In order to help policymakers to develop long-term perspectives of the need for cooperation for optimal use of water available in the tributaries of the Ganges, the Institute was involved in a major track-two exercise for over five years during the 1990s. The Institute has been undertaking a series of exercises in the form of p- lication and dissemination of study findings in the field since the early 1990's. In that series, this book is the latest one and is published in collaboration with Springer Science + Business Media BV, Dordrecht, The Netherlands.

This edition of its popular predecessor has been significantly revised to increase flexibility in the presentation and maintain greater continuity of the material. Combining both theory and practical applications of empirical equations the text contains expanded treatment of water quantity and quality control, a detailed presentation of basic principles and use in analysis and design, hydrograph topics including synthetic and convolution techniques, practical and realistic case studies relating to design problems, and additional end-of-chapter problems. It provides new computer programs to explain complex concepts and solve large data-based problems. An additional appendix offers suggestions for classroom or lab problems.

Rising at 11,750 feet in the Sangre de Cristo range and snaking 926 miles through New Mexico and Texas to the Rio Grande, the Pecos River is one of the most storied waterways in the American West. It is also one of the most troubled. In 1942, the National Resources Planning Board observed that the Pecos River basin ""probably presents a greater aggregation of problems associated with land and water use than any other irrigated basin in the Western U.S."" In the twenty-first century, the river's problems have only multiplied. Bitter Waters, the first book-length study of the entire Pecos, traces the river's environmental history from the arrival of the first Europeans in the sixteenth century to today. Running clear at its source and turning salty in its middle reach, the Pecos River has served as both a magnet of veneration and an object of scorn. Patrick Dearen, who has written about the Pecos since the 1980s, draws on more than 150 interviews and a wealth of primary sources to trace the river's natural evolution and man's interaction with it. Irrigation projects, dams, invasive saltcedar, forest proliferation, fires, floods, flow decline, usage conflicts, water quality deterioration - Dearen offers a thorough and clearly written account of what each factor has meant to the river and its prospects. As fine-grained in detail as it is sweeping in breadth, the picture Bitter Waters presents is sobering but not without hope, as it also extends to potential solutions to the Pecos River's problems and the current efforts to undo decades of damage. Combining the research skills of an accomplished historian, the investigative techniques of a veteran journalist, and the engaging style of an award-winning novelist, this powerful and accessible work of environmental history may well mark a turning point in the Pecos's fortunes.

In 2017 four rivers in Aotearoa New Zealand, India, and Colombia were given the status of legal persons, and there was a recent attempt to extend these rights to the Colorado River in the USA. Understanding the implications of creating legal rights for rivers is an urgent challenge for both water resource management and environmental law. Giving rivers legal rights means the law can see rivers as legal persons, thus creating new legal rights which can then be enforced. When rivers are legally people, does that encourage collaboration and partnership between humans and rivers, or establish rivers as another competitor for scarce resources? To assess what it means to give rivers legal rights and legal personality, this book examines the form and function of environmental water managers (EWMs). These organisations have legal personality, and have been active in water resource management for over two decades. EWMs operate by acquiring water rights from irrigators in rivers where there is insufficient water to maintain ecological health. EWMs can compete with farmers for access to water, but they can also strengthen collaboration between traditionally divergent users of the aquatic environment, such as environmentalists, recreational fishers, hunters, farmers, and hydropower. This book explores how EWMs use the opportunities created by giving nature legal rights, such as the ability to participate in markets, enter contracts, hold property, and enforce those rights in court. However, examination of the EWMs unearths a crucial and unexpected paradox: giving legal rights to nature may increase its legal power, but in doing so it can weaken community support for protecting the environment in the first place. The book develops a new conceptual framework to identify the multiple constructions of the environment in law, and how these constructions can interact to generate these unexpected outcomes. It explores EWMs in the USA and Australia as examples, and assesses the implications of creating legal rights for rivers for water governance. Lessons from the EWMs, as well as early lessons from the new 'river persons,' show how to use the law to improve river protection and how to begin to mitigate the problems of the paradox.

This book focuses on governance and management issues in the much publicized 'Ganga Rejuvenation Project', led by the Indian Prime Minister Mr. Narendra Modi. Attempts over the past three decades to clean up and rejuvenate one of the world's greatest rivers have proved futile. The major reasons for the lack of success are absence of long-term planning, poor co-ordination and failure to sustain whatever little infrastructure for water and sewage treatment could be developed. Focusing on these broad aspects, the book explores spaces for better governance through active community participation, knowledge management, prospects of Public-Private-Partnership, e-governance, youth education, waterfront development, lessons from past failures, comparative international analogies, utilization of external aid and global expertise in successful implementation of a sustainable long-term plan for a river basin's integrated development of both the economy and environment. A host of activities, such as, improving pollution monitoring systems, new development plans for tourism enhancement; river dredging and sewering riparian cities are already being carried in the hope of quick results. The Government of India has also appointed a task force for preparation of a long-term strategy. However, substantial knowledge gaps persist especially with regard to governance. This book aims to address the governance and policy issues and will be a very timely contribution to cleaning as well as rejuvenating Ganga, a river that is lifeline of millions of people.

Water-although it covers more than two-thirds of the earth's surface, clean, potable water is in critically short supply. As more and more people globally show greater interest in what their religious traditions say about our natural world, Troubled Waters: Religion, Ethics, and the Global Water Crisis examines the central role of water in various traditions and rituals, arriving at creative new ways to approach the growing water crisis worldwide. Chamberlain outlines many of the current water problems and lays out clear principles for action that engaged citizens from various traditions can undertake to meet the growing water challenges through conservation and water management policies. The book describes many religious practices from around the world that help sustain and restore water by using new technologies and reviving old ones. Offering creative suggestions for both personal practices and group action, Chamberlain advocates conservation, preservation, and restoration of our troubled waters.

This book offers a comprehensive review of how plastic pollution is affecting fresh and marine waters, and what the current challenges in plastic waste assessment and management in the aquatic environment are. Plastic waste comprises particles with heterogeneous physicochemical properties such as large size-range, different shapes and polymer types with various additives determining their environmental fate and risk. This complexity raises several open research questions which are explored in this book. Examples are the plastic uptake by aquatic organisms, degradation processes as well as sources and sinks in the environment. Readers will discover real case studies of plastic pollution detection and management in different parts of the world, including Asia, America and Europe, which provide an integrated overview of the global scope of this issue. This book and the companion volume Plastics in the Aquatic Environment - Part II: Stakeholders' Role Against Pollution are valuable resources to students, researchers, policymakers and environmental managers interested in plastic pollution and working towards its reduction.

First Published in 2006. Routledge is an imprint of Taylor & Francis, an informa company.

This collection addresses the complexities of water management and the impact of environmental developments such as dams, reservoirs and irrigation schemes on public health. The main focus of the book is on vector-borne diseases such as malaria, arboviruses (dengue and encephalitides) and snail- borne schistosomiasis. These are examined from a wide range of intersectoral perspectives which encompass disciplines with often conflicting interests, for instance agriculture, aquaculture, urban development, social development, water management and recreation. The book explains developmental processes, such as the construction of man-made lakes, and addresses broad practical and policy-making issues. Most importantly, the book offers many innovative solutions to assist readers who work in the water industry, whether through administration or science and engineering disciplines. Contributions from an international team of experts provide numerous case studies from around the world (Australia, Indonesia, Thailand, USA), which illustrate both poor and successful water management. The contributors provide historical and current coverage of the environmental and health issues prevalent in the field, but also gaze prospectively on the future development of constructed wetlands, aquaculture, urban development and funding agency policies, with the view to managing water resources more effectively and safely. This authoritative and comprehensive book is written in an accessible, non-technical manner and will be of interest to those involved in various aspects of water management and delivery, whether biologically skilled or not.

Until recently, focus on groundwater mainly concerned its use as drinking water and as an important resource for industry (e.g. cooling waters) and agriculture (irrigation). It has, however, become increasingly obvious that groundwater should not only be viewed as a drinking water reservoir, but that it should also be protected for its environmental value. In this respect, groundwater represents an important link of the hydrological cycle through the maintenance of wetlands and river flows, acting as a buffer through dry periods. Hence, deterioration of groundwater quality may directly affect other related aquatic and terrestrial ecosystems. The groundwater legislative framework under the EU Water Framework Directive and the newly adopted Groundwater Directive establishes criteria linked to environmental objectives which have to be met by 2015 following successive operational steps including characterisation, risk assessment (analysis of pressures and impacts), monitoring and design of programmes of measures. These milestones require that sound technical and scientific information be made accessible to water managers, which is so far still not sufficiently streamlined. In this context, this book describes the groundwater legislative milestones and presents series of research and development activities that aim to directly support them. It has, therefore, the ambition to become a vehicle liaising policy requirements and available scientific knowledge in this area.

The large lakes of the East African Rift Valley are among the oldest on Earth, and are vital resources for the people of their basins. They are unique among the large lakes of the world in terms of their sensitivity to climatic change, rich and diverse populations of endemic species, circulation dynamics and water-column chemistry, and long, continuous records of past climatic change. A comprehensive study of the large African lakes is long overdue. The scientific justification for such an effort is noted in the previous paragraph and is illustrated in great detail in this volume. Societal need for the sustainable utilization of these lakes offers an even more compelling reason for examination of biological food webs, water quality, and past climate variability in East Africa. The lakes provide the most important source of protein for the people of the African Rift Valley, and fish populations are shifting dramatically in response to fishing pressure, introduction of exotic species, land use impact on water quality, and perhaps climatic change. Current estimates of primary productivity, the underpinning of the food resource, are extremely crude and based on only a few spot measurements.

Vadose Zone Hydrology describes the elements of the physical processes most often encountered by hydrogeologists and ground-water engineers in their vadose zone projects. It illustrates the application of soil physics to practical problems relevant to the characterization and monitoring of the vadose zone. It includes an introduction to physical processes, including basic flow theory, and provides examples of important field-scale processes that must be recognizable by hydrogeologists. Considerable attention is given to the concepts of recharge, including how it is most accurately evaluated in the vadose zone. Field and laboratory methods for characterizing hydraulic properties in the vadose zone are also covered, and case studies illustrating these methods are provided. New and emerging technologies for monitoring the vadose zone, particularly for the purpose of detecting contaminants, are highlighted. In the last section of the book, additional case studies are presented, demonstrating applications related to seepage detection, landfill monitoring, and soil gas investigations. This book is written from the perspective of hydrogeologists and is designed to be directly applicable and to maintain continuity and consistency between chapters. It will be an invaluable primer for environmental or geotechnical consultants, regulators, or students who have no prior formal academic training in unsaturated flow concepts. Because the text contains some of the latest advances in this field, it will be an excellent reference for geologists and engineers currently working on problems of vadose zone hydrology.
