This volume to discussing the various aspects of estuarine water quality modeling. Topics considered include fundamental principles, estuarine mass transport, BOD/DO and eutrophication model kinetics, kinetics on toxicants, and sediment-water interactions. The book also discusses mixing zone modeling and how to integrate estuarine hydrodynamic and water quality models. Many case studies demonstrating successful model applications are discussed.

Metal contamination of groundwater results from many human activities, including agriculture, mining, and the disposal of municipal waste and fly ash. Metals in Groundwater describes the transport of metals to groundwater from these and other sources. It also covers risk assessment of metals in groundwater, coupling of chemicals and hydrological models, and sorption of metals onto soils and clays. The speciation of metals is examined in detail. The book will interest researchers in environmental quality, mining, and agriculture; consultants; industry professionals; and personnel within regulatory agencies.

Freshwater ecosystems have the greatest species diversity per unit area and many endangered species. This book shows that, rather than being a marginal part of terrestrial protected area management, freshwater conservation is central to sustaining biodiversity. It focuses on better practices for conserving inland aquatic ecosystems in protected areas, including rivers, wetlands, peatlands, other freshwater and brackish ecosystems, and estuaries. The authors define inland aquatic ecosystems, showing just how diverse and widespread they are. They examine the principles and processes that are essential for the conservation of freshwater ecosystems and aquatic species. Major categories of threats to freshwater ecosystems and the flow-on implications for protected area design are described. Practical case studies are used to illustrate principles and practices applied around the world. Specific management needs of the main types of freshwater ecosystems are considered, as well as the management of freshwaters in the broader landscape, showing how natural resource governance processes can be harnessed to better manage freshwater biodiversity. The book offers commentary on how to adapt freshwater conservation practices to climate change and ends with an insightful synthesis.

This book reviews the sources of soil and groundwater contamination and the potential remediation technologies. It focuses on remediation technologies that are commonly utilized in practice, and discusses a number of innovative technologies that show promise for special problem circumstances.

This volume provides useful insight on the differing approaches to water quality issues and the diversity of strategies in water quality management worldwide. This book is divided into two parts: The first part deals with aspects of water quality in various countries and several remedies are suggested. Also considered are theoretical and practical topics including policy and resource management. The second part discusses water as a world problem in both developed and developing countries. Aspects of the problem relating to seas, deserts, forests and freshwater are examined with reference to planning, development and environmental impact analysis.

Groundwater abstraction plays a very important part in water supplies throughout the world. Yet too many wells and boreholes operate inefficiently or are abondoned. Until relatively recently, very many water well operators had valuable assets in the form of groundwater abstraction works, of which they really had little idea of condition or operating efficiency. Inadequate monitoring and little if any maintenance occurred. As long as some water was gained little else seemed to matter. If a well failed for some reason, then it was often abandoned and water obtained quickly via an engineering solution varying from drilling a new well, to manipulation of other parts of the supply/distribution system. Rehabilitation, if attempted, was on a "suck-it-and-see" basis and frequently failed. Such approaches prevail in many parts of the world. Yet it must be regarded as particularly serious in developing countries where weak economies could well do without the added strain of supporting inefficient systems or where failure can simply lead to going without. The author, in this book explains how today attitudes are changing. Whereas maintenance and rehabilitation used to lack glamour, and were o

Hydrology and Global Environmental Change presents the hydrological contribution to, and consequences of, global environmental change. Assuming little or no prior knowledge on the part of the reader, the book looks at the main processes of global environmental change - global scale processes, large regional processes, repetitive processes - and how the hydrological cycle, processes and regimes impact on GEC and vice-versa.

The Ganges is one of the most complex yet fascinating river systems in the world. The basin is characterized by a high degree of heterogeneity from climatic, hydrological, geomorphological, cultural, environmental and socio-economic perspectives. More than 500 million people are directly or indirectly dependent upon the Ganges River Basin, which spans China, Nepal, India and Bangladesh. While there are many books covering one aspect of the Ganges, ranging from hydrology to cultural significance, this book is unique in presenting a comprehensive inter-disciplinary overview of the key issues and challenges facing the region. Contributors from the three main riparian nations assess the status and trends of water resources, including the Himalayas, groundwater, pollution, floods, drought and climate change. They describe livelihood systems in the basin, and the social, economic, geopolitical and institutional constraints, including transboundary disputes, to achieving productive, sustainable and equitable water access. Management of the main water-use sectors and their inter-linkages are reviewed, as well as the sustainability and trade-offs in conservation of natural systems and resource development such as for hydropower or agriculture.

This book addresses a timely and compelling emerging issue related to the conservation and sustainable use of marine resources and the sustainable development of the coastal community. Marine protected areas (MPAs) make a remarkable contribution to the protection of marine communities by providing sustainable livelihoods, deriving financial benefits from the development of fisheries and tourism, as well as by restoring ocean productivity and preventing further environmental degradation. These areas have been considered the cornerstone of a blue economy due to their substantial economic, social and environmental contributions. However, MPAs around the world are severely hampered by a multitude of issues and challenges such as inefficient management, poor socioeconomic conditions and environmental degradation due to human activities, overexploitation of marine resources, degradation of water quality, massive waste production and climate change. These are the main obstacles to economic, social and environmental sustainability. Hence, a collaborative management approach and an integrated management policy framework is urgently needed for the economic, social, political, cultural, technological, and ecological development of coastal communities.

The contamination of environment and water resources by Selenium (Se) and its oxyanions from various sources are emerging contaminants of significant health and environmental concern. The primary sources include agricultural drainage water, mine drainage, residues from fossil fuels, thermoelectric power plants, oil refineries, and metal ores. Various methods and technologies have been developed which focus on the treatment of selenium-containing waters and wastewater. High concentrations of selenium in water cause various adverse impact to human health, such as carcinogenic, genotoxic, and cytotoxic effects. But in the lower concentrations, it is a useful constituent of the biological system. The range between toxicity and deficiency of selenium is minimal (40 to 400 g per day), due to its dual nature. Selenium Contamination in Water contains the latest status and information on selenium's origin, its chemistry and its toxicity to humans. The book represents a comprehensive and advanced reference book for students, researchers, practitioners, and policymakers in working in the field of metalloids, in particular selenium. A special emphasis is given on its geological distribution, monitoring techniques, and remedial technologies. As such, the authors critically analyze the various techniques used for the monitoring and removal of selenium from water. Featuring chapters arranged according to the major themes of the latest research, with specific case-studies from industrial experiences of selenium detection and removal, Selenium Contamination in Water will be particularly valued by researchers, practitioners, and policymakers in working in the field of metalloids including selenium.

Since time before memory, large numbers of salmon have made their way up and down the Klamath River. Indigenous management enabled the ecological abundance that formed the basis of capitalist wealth across North America. These activities on the landscape continue today, although they are often the site of intense political struggle. Not only has the magnitude of Native American genocide been of remarkable little sociological focus, the fact that this genocide has been coupled with a reorganization of the natural world represents a substantial theoretical void. Whereas much attention has (rightfully) focused on the structuring of capitalism, racism and patriarchy, few sociologists have attended to the ongoing process of North American colonialism. Salmon and Acorns Feed Our People draws upon nearly two decades of examples and insight from Karuk experiences on the Klamath River to illustrate how the ecological dynamics of settler-colonialism are essential for theorizing gender, race and social power today.

Decades, or even centuries, of changing and competing land uses have left many of the world's streams degraded, in poor health, and out of balance with the ever-shifting dynamics of their watersheds. This is a basic resource intended to help individuals, groups, organizations, companies, communities, and governments plan and carry out environmentally sound, cost-effective stream corridor assessment, enhancement, and stewardship programs. Using the watershed as the basic unit of reference, the Handbook provides ideas and information with which readers can assess and document local stream conditions, learn about and evaluate methods of enhancement, devise and implement enhancement plans, and then maintain the stream and stream corridor in its enhanced state of better health and balance. While not a comprehensive technical manual for professionals trained in stream restoration, this resource does provide a solid foundation by which volunteers may become informed observers, advocates, and organizers of stream enhancement programs and participants in their implementation.

This is a concise introduction to principles and applications of hydrology in a geographical context. It uses a wealth of fully illustrated examples to relate theory to the real geographical problems associated with a subject central to our understanding of the natural environment and the use we make of it. Whilst hydrology and the study of water resources have been established for sometime as topics for advanced study, they have been introduced into A-level syllabuses only recently. Elements of Geographical Hydrology is one of the first books aiming to serve the specific requirements at this level. It provides a sound introduction to the theory and principles of hydrology and illustrates them by means of examples. It then proceeds to show the relevance of hydrology to several important aspects of geography, namely: soil studies, hillslope development, and water resource management. It relies throughout on detailed examples, an approach which should enliven the subject and provide substantial material to bring home its realities and reinforce the reader's understanding. The book is fully illustrated with many line drawings and photographs, all of which are closely linked with the text. It offers opportunities for the reader to test his or her understanding of the subject by means of problem exercises. A selected and annotated list of further reading indicates the most useful and accessible sources of more comprehensive and advanced material.

In his memoir, Life on the Mississippi, Mark Twain personified the river as "Sudden Death and General Desolation! Sired by a hurricane, dam'd by an earthquake, half-brother to the cholera, nearly related to the small-pox on the mother's side! Look at me! I take nineteen alligators and a bar'l of whiskey for breakfast when I'm in robust health, and a bushel of rattlesnakes and a dead body when I'm ailing!" Twain's time as a steamboat pilot showed him the true character of The Great River, with its unpredictable moods and hidden secrets. Still a vital route for U.S. shipping, the Mississippi River has given life to riverside communities, manufacturing industries, fishing, tourism, and other livelihoods. But the Mighty Mississippi has also claimed countless lives as tribute to its muddy waters. Climate and environmental conditions made the Mississippi the perfect incubator for diseases like malaria. Natural disasters like tornadoes, floods, and even an earthquake have changed and reshaped the river's banks over thousands of years. Shipwrecks and steamboat explosions were once common in the difficult-to-navigate waters. But when there was money to be made, there were some willing to risk it all-from the brave steamboat captains who went down with their ships, to the illegal moonshiners and pirates who pillaged the river's bounty. In this book, author and Mississippi River historian Dean Klinkenberg explores the many disastrous events to have occurred on and along the river in the nineteenth and twentieth centuries-from steamboat explosions, to Yellow Fever epidemics, floods, and Prohibition piracy. Enjoy this journey into the darkest deeds of the Mississippi River.

While there are several excellent books dealing with numerical analysis and analytical theory, one has to practically sift through hundreds of references. This monograph is an attempt to partly rectify this situation. It aims to introduce the application of finite-difference methods to ocean dynamics as well as review other complex methods. Systematically presented, the monograph first gives a detailed account of the basics and then go on to discuss the various applications. Recognising the impossibility of covering the entire field of ocean dynamics, the writers have chosen to focus on transport equations (diffusion and advection), shallow water phenomena - tides, storm surges and tsunamis, three-dimensional time dependent oceanic motion, natural oscillations, and steady state phenomena. The many aspects covered by this book makes it an indispensable handbook and reference source to both professionals and students of this field.

Water plays an important part in today's environmental concerns. Since the publication of the first edition there have been rapid developments in the application of hydrology, geomorphology and ecology to stream management. In particular, growth has occurred in the areas of stream rehabilitation and the evaluation of environmental flow needs. The concept of stream health has been adopted as a way of assessing stream resources and setting management goals.

"Stream Hydrology: An Introduction for Ecologists Second Edition" documents recent research and practice in these areas. Chapters provide information on sampling, field techniques, stream analysis, the hydrodynamics of moving water, channel form, sediment transport and commonly used statistical methods such as flow duration and flood frequency analysis. Methods are presented from engineering hydrology, fluvial geomorphology and hydraulics with examples of their biological implications. This book demonstrates how these fields are linked and utilised in modern, scientific river management. "Emphasis on applications, from collecting and analysing field measurements to using data and tools in stream management." "Updated to include new sections on environmental flows, rehabilitation, measuring stream health and stream classification." "Critical reviews of the successes and failures of implementation." "Revised and updated windows-based software." This book is essential reading for 2nd/3rd year undergraduates and postgraduates of hydrology, stream ecology and fisheries science in Departments of Physical Geography, Biology, Environmental Science, Landscape Ecology, Environmental Engineering and Limnology. It would be valuable reading forprofessionals working in stream ecology, fisheries science and habitat management, environmental consultants and engineers.

The potential impact of global warming on water resources is of major national and international concern. This book draws together for the first time research work aimed at providing global and regional syntheses of the likely hydrological effects of climate change over the coming century. The chapters in this volume range from pioneering assessments at continental and sub-continental scale, to the development of new methodological approaches for down-scaling climatic predictions, analyses of recent trends in hydrometric data, and reviews of ongoing research on regional hydrological impacts. Although it is still early days for climatic impact prediction, the book demonstrates considerable unaniminity in its general conclusions. Audience: This book will be of major interest to water resource planners and researchers involved in assessing the impact of climate change. It also provides valuable material for lecture courses in hydrology, water resources and climatic impact.

For many years the reduction of eutrophication in the Baltic Sea has been a hot issue for mass-media, science, political parties and environmental action groups with manifold implications related to fisheries (will the Baltic cod survive?), sustainable coastal development (have billions of Euros been wasted on nitrogen reductions?), ecotoxicology (can we safely eat Baltic fish?). This book takes a holistic process-based ecosystem perspective on the eutrophication in the Baltic Sea, with a focus on the factors regulating how the system would respond to changes in nutrient loading. This includes a very special process for the Baltic Sea: land uplift. After being depressed by the glacial ice, the land is now slowly rising adding vast amounts of previously deposited nutrients and clay particles to the system. 110,000 to 140,000 tons of phosphorus per year are added to the system from land uplift, in comparison to the 30,000 tons of phosphorus per year from rivers. The added clay particles function in ways similar to which clay particles of benthonite function in the wine industry: namely as a clarifier. Paradoxically, in spite of the fact that so many nutrients are added to the system from land uplift, the Baltic Sea would have an even higher nutrient concentration than at present, had it not been for the impact of the clay particles from land uplift. These results motivate a major revision of the outlook and understanding of the structure and function of the Baltic Sea ecosystem. The book also presents a remedial strategy aimed at combating eutrophication in the Baltic Sea which challenges the accepted remedial strategy.

Hydrology in Practice is an excellent and very successful introductory text for engineering hydrology students who go on to be practitioners in consultancies, the Environment Agency and elsewhere. It has never been superseded by any other text in this respect.

This fourth edition of Hydrology in Practice while retaining all that is excellent about its predecessor, by Elizabeth M. Shaw, replaces the material on the Flood Studies Report with an equivalent section on the methods of the Flood Estimation Handbook and its revisions. Other completely revised sections on instrumentation and modelling reflect the many changes that have occurred over recent years. The updated text has taken advantage of the extensive practical experience of the staff of JBA Consulting who use the methods described on a day-to-day basis. Topical case studies further enhance the text and the way in which students at undergraduate and MSc level can relate to it. The fourth edition will also have a wider appeal outside the UK by including new material on hydrological processes which also relate to courses in geography and environmental science departments. In this respect the book draws on the expertise of Keith J. Beven and Nick A.Chappell who have extensive experience of field hydrological studies in a variety of different environments, and teaching undergraduate hydrology courses for many years.

Second and final year undergraduates (and MSc) students of hydrology in Engineering, Environmental Science and Geography Departments across the globe, as well as professionals in environmental protection agencies and consultancies, will find this book invaluable. It is likely to be the course text for every undergraduate/MSc hydrology course in the UK and in many cases overseas too.

‘Brilliant, clear, and humane’ Elizabeth Gilbert, author of Eat, Pray, Love ‘Miraculous and hopeful’ Emma Straub, author of All Adults Here ‘Quietly profound … belongs on the shelf next to Jon Krakauer’s Into the Wild’ New York Times Riverman: An American Odyssey uncovers the story of an extraordinary man and his puzzling disappearance, and paints a picture of the singular spirit of America’s riverbank towns. ‘The peace of mind I found, largely alone, on that white-water mecca convinced me that life was capable of exquisite pleasure and undefined meaning deep in the face of failure. The experience itself is the reward.’ Dick Conant On his forty-third birthday, Dick Conant, a golden boy who never quite grew up as those around him expected, stepped into a homemade boat to embark on a journey despite a gathering snowstorm. Among his possessions was a Gideon Bible and biographies of Einstein and Bismark. It was the beginning of an all-consuming odyssey by an unconventional man into the watery arteries of America, a journey to the unreported margins of society. He was to spend the next twenty years canoeing thousands of miles of rivers and their innumerable smaller tributaries, from one end of the country to the other. ‘I can, and I will!’ he said. And then, in 2014, he disappeared. Not long before Conant’s upturned canoe was found in a brackish North Carolina bay, Ben McGrath met Conant by chance as he paddled down the Hudson, headed for Florida. McGrath set out to find the people whose lives, like his own, had been touched by their encounter with the great river wanderer. Along the way he meets eccentrics and ne’er-do-wells drawn straight from the pages of Mark Twain, a vast network of friends and acquaintances who would forever remember this brilliant and charming man even after a single meeting. Riverman is the story of a restless soul who was as troubled as he was charismatic, a contemporary folk hero who slips the moorings of ordinary civilised life to tap into what Thoreau called ‘a yearning toward all wildness.’ It is also a riveting portrait of an America we rarely see: a nation of unconventional characters, small river towns, and long forgotten waterways.

This is the second monograph by the author on biological materials of marine origin. The initial book is dedicated to the biological materials of marine invertebrates. This work is a source of modern knowledge on biomineralization, biomimetics and materials science with respect to marine vertebrates. For the first time in scientific literature the author gives the most coherent analysis of the nature, origin and evolution of biocomposites and biopolymers isolated from and observed in the broad variety of marine vertebrate organisms (fish, reptilian, birds and mammals) and within their unique hierarchically organized structural formations. There is a wealth of new and newly synthesized information, including dozens of previously unpublished images of unique marine creatures including extinct, extant and living taxa and their biocomposite-based structures from nano- to micro - and macroscale. This monograph reviews the most relevant advances in the marine biological materials research field, pointing out several approaches being introduced and explored by distinct modern laboratories.

Any sustainable groundwater development programme requires knowledge of the prevailing flow system, extending from local to regional scale. This book of selected papers discusses integral groundwater management with scale flow issues and presents methods of defining, preventing, controlling and mitigating negative environmental impacts related to groundwater. It highlights specific issues such as trans-boundary groundwater flow, groundwater recharge, groundwater mining, and groundwater flow in thick aquifers, and stresses the importance of the sustainable development of groundwater and its social and economic implications. The book will interest groundwater researchers and professionals, students, government administrators and educators, providing new insights into the procedures and processes that are influenced by the scale of the groundwater flow system.
