Touching all parts of the natural environment and nearly all aspects of human culture, streams and rivers act as centers of organization within landscapes. They provide natural resources such as fish and clean water, transportation, energy, diffusion of wastes, and recreation. Today, with unprecedented demands on streams and rivers by an exponentially increasing human population, a basic ecological understanding of the structure and dynamics of running waters is essential for formulating sound management and policy decisions. The vast Pacific coastal ecoregion of the United States contains an extraordinary array of physical settings and examples of the range of dynamics associated with rivers and their management. The interface between the science and policy of natural resource management is illustrated by examples from this ecoregion, including the protection of riparian forest, the marbled murrelet, salmon, and amphibians. River Ecology and Management: Lessons from the Pacific Coastal Ecoregion includes sections on the Physical Environment, the Biotic Environment, Ecosystem Processes, Management, and Recommendations for the Future. Specific topics include channel dynamics, hydrology, water quality, microbial processes, primary production, fish and wildlife, riparian forest dynamics, organic matter and trophic dynamics, biogeochemical cycling, maintaining biodiversity, monitoring and assessment, economic perspectives, legal considerations, and the role of non-governmental organizations in river management. "The wealth of science and literature in the book renders it a useful summary and reference for aquatic and watershed researchers, and most of the concepts and applications extend beyond the ecoregion¿.The lessons to be learned from the history, conceptual paradigms, research findings, and management approaches presented in this book are many and varied." --Ecology

This latest collaboration of Carolyn V. Platt and Gary Meszaros is a beautifully photographed book that explores Lake Erie and its effects on the birds that make this region their home. Birds of the Lake Erie Region observes a year of weather changes and avian migrations--from the wintertime convergence of ducks and other waterbirds on the lake's last ice-free areas to the excitement of the raptor and shorebird migrations in the fall. Expert or novice, birders and nature lovers will be moved by Platt's celebration of these birds and their habitat and by Meszaros's impressive photographs of the delicate beauty of these exquisite creatures.

In The Big Muddy, the first long-term environmental history of the Mississippi, Christopher Morris offers a brilliant tour across five centuries as he illuminates the interaction between people and the landscape, from early hunter-gatherer bands to present-day industrial and post-industrial society. Morris shows that when Hernando de Soto arrived at the lower Mississippi Valley, he found an incredibly vast wetland, forty thousand square miles of some of the richest, wettest land in North America, deposited there by the big muddy river that ran through it. But since then much has changed, for the river and for the surrounding valley. Indeed, by the 1890s, the valley was rapidly drying. Morris shows how centuries of increasingly intensified human meddling-including deforestation, swamp drainage, and levee construction-led to drought, disease, and severe flooding. He outlines the damage done by the introduction of foreign species, such as the Argentine nutria, which escaped into the wild and are now busy eating up Louisiana's wetlands. And he critiques the most monumental change in the lower Mississippi Valley-the reconstruction of the river itself, largely under the direction of the Army Corps of Engineers. Valley residents have been paying the price for these human interventions, most visibly with the disaster that followed Hurricane Katrina. Morris also describes how valley residents have been struggling to reinvigorate the valley environment in recent years-such as with the burgeoning catfish and crawfish industries-so that they may once again live off its natural abundance. Morris concludes that the problem with Katrina is the problem with the Amazon Rainforest, drought and famine in Africa, and fires and mudslides in California-it is the end result of the ill-considered bending of natural environments to human purposes.

With the eye of a professional scientist and the passion of a dedicated amateur, E. C. Pielou conducts a guided tour of fresh water on its course through the natural world. As the world's supply of clean, fresh water continues to dwindle, it becomes increasingly important to understand the close connection between water and all forms of life. Pielou's fascination with fresh water gives us a "natural history" that is remarkable and surprising.
"[A] keen and detailed look at the life and history of fresh water. . . . Dip into Fresh Water. It will both stimulate and satisfy as only good natural history can."--"Toronto Globe and Mail"
"Pielou's ease with her subject and her no-nonsense style of writing will satisfy and inspire the poet as well as the naturalist."--Denize Springer, "Express Books"
"[Pielou's] writing is didactic and definitive, in places even charming, and is buttressed by clear illustrations. . . . A welcome addition to the genre of literature designed to bridge the gap between scientists . . . and the intelligent and concerned lay public."--Daniel Hillel, "Nature"
"A wonderful natural history of one of life's necessities, a refreshing break from the grand theory and special pleading of many a science book. . . . Read it."--Fred Pearce, "New Scientist"

The Nile, one of the world's great rivers, has long been an object of fascination and obsession. From Alexander the Great and Nero, to Victorian adventurers David Livingstone, John Hanning Speke, and Henry Morton Stanley, the river has enticed many into wild adventures. English writer, photographer, and explorer Levison Wood continues that tradition, and Walking the Nile is the captivating account of his remarkable and unparalleled Nile journey. Starting in November 2013 in a forest in Rwanda, where a modest spring spouts a trickle of clear, cold water, Wood set forth on foot, aiming to become the first person to walk the entire length of the fabled river. He followed the Nile for nine months, over 4,000 miles, through six nations--Rwanda, Tanzania, Uganda, South Sudan, the Republic of Sudan, and Egypt--to the Mediterranean coast. Like his predecessors, Wood camped in the wild, foraged for food, and trudged through rainforest, swamp, savannah, and desert, enduring life-threatening conditions at every turn. He traversed sandstorms, flash floods, minefields, and more, becoming a local celebrity in Uganda, where a popular rap song was written about him, and a potential enemy of the state in South Sudan, where he found himself caught in a civil war and detained by the secret police. As well as recounting his triumphs, like escaping a charging hippo and staving off wild crocodiles, Wood's gripping account recalls the loss of Matthew Power, a journalist who died suddenly from heat exhaustion during their trek. As Wood walks on, often joined by local guides who help him to navigate foreign languages and customs, Walking the Nile maps out African history and contemporary life. An inimitable tale of survival, resilience, and sheer willpower, Walking the Nile is an inspiring chronicle of an epic journey down this lifeline of civilization.

The challenges that the world's running water systems now face have never been more numerous or acute; at the same time, these complex habitats remain absolutely crucial to human wellbeing and future survival. If rivers can ever be anything like sustainable, ecology needs to take its place as an equal among the physical sciences such as hydrology and geomorphology. A real understanding of the natural history and ecology of running waters must now be brought even more prominently into river management. The primary purpose of this textbook is to provide the up-to-date overview that students and practitioners will require to achieve this aim. The book's unifying focus is on rivers and streams as ecosystems in which the particular identity of organisms is not the main emphasis but rather the processes in which they are involved - specifically energy flow and the cycling of materials. It builds on the physicochemical foundations of the habitat templet and explores the diversity and adaptations of the biota, progressing from the population and community ecology of organisms and linking them to ecosystem processes and services in the wider biosphere via the complexities of species interactions and food webs. These include water quality and patterns of river discharge, as well as aesthetics, waste disposal, and environmental health. While the book is not primarily focused on application per se, each chapter addresses how humans affect rivers and, in turn, are affected by them. A final, future-oriented chapter identifies key strategic areas and sets a roadmap for integrating knowledge of natural history and ecology into policy and management. The Biology and Ecology of Streams and Rivers is an accessible text suitable for both senior undergraduate and graduate students taking courses in both lotic and general ecology as well as more established researchers, practitioners, managers, and conservationists requiring a concise and contemporary overview of running waters.

Since its establishment as a federally protected wilderness in 1964, the Boundary Waters has become one of our nation's most valuable-and most frequently visited-natural treasures. When Amy and Dave Freeman learned of toxic mining proposed within the area's watershed, they decided to take action-by spending a year in the wilderness, and sharing their experience through video, photos, and blogs with an audience of hundreds of thousands of concerned citizens. This book tells the deeper story of their adventure in northern Minnesota: of loons whistling under a moonrise, of ice booming as it forms and cracks, of a moose and her calf swimming across a misty lake. With the magic-and urgent-message that has rallied an international audience to the campaign to save the Boundary Waters, A Year in the Wilderness is a rousing cry of witness activism, and a stunning tribute to this singularly beautiful region.

In Down the Wild Cape Fear, novelist and nonfiction writer Philip Gerard invites readers onto the fabled waters of the Cape Fear River and guides them on the 200-mile voyage from the confluence of the Deep and Haw Rivers at Mermaid Point all the way to the Cape of Fear on Bald Head Island. Accompanying the author by canoe and powerboat are a cadre of people passionate about the river, among them a river guide, a photographer, a biologist, a river keeper, and a boat captain. Historical voices also lend their wisdom to our understanding of this river, which has been a main artery of commerce, culture, settlement, and war for the entire region since it was first discovered by Verrazzano in 1524. Gerard explores the myriad environmental and political issues being played out along the waters of the Cape Fear. These include commerce and environmental stewardship, wilderness and development, suburban sprawl and the decline and renaissance of inner cities, and private rights versus the public good.

Nematodes are the most numerous metazoans in aquatic sediments. The majority of conducted studies on these aquatic forms focus mainly on those in marine and estuarine habitats. Nematodes from inland water bodies have been relatively forgotten or ignored. Recognizing this serious drawback and its impact on research on nematodes, this book brings together the available information on freshwater nematodes. It addresses the taxonomy of this extremely diverse phylum and provides analysis of its ecology in freshwater habitats from nematologists from 12 countries worldwide. Descriptions of each taxon at genus-level and above are provided with an augmenting pictorial guide to the currently valid genera. Also, a complete, up-to-date and valid species-list is given for every genus with an emphasis on those reported from freshwater bodies.

Stretching along 156 miles of Florida's East Coast, the Indian River Lagoon contains the St. Lucie estuary, the Mosquito Lagoon, Banana River Lagoon, and the Indian River. It is a delicate ecosystem of shifting barrier islands and varying salinity levels due to its many inlets that open and close onto the ocean. The long, ribbon-like lagoon spans both temperate and subtropical climates, resulting in the most biologically diverse estuarine system in the United States. Nineteen canals and five man-made inlets have dramatically reshaped the region in the past two centuries, intensifying its natural instability and challenging its diversity. Indian River Lagoon traces the winding story of the waterway, showing how humans have altered the area to fit their needs and also how the lagoon has influenced the cultures along its shores. Now stuck in transition between a place of labor and a place of recreation, the lagoon has become a chief focus of public concern. This book provides a much-needed bigger picture as debates continue over how best to restore this natural resource.

First published in 1982, the purpose of this textbook is to present civil engineers with sufficient information about geology to enable them to understand those aspects of the behaviour and properties of rock and soil that are relevant to the design of buildings, bridges, highways and dams. Geotechnical surveys are made so that building design can be matched to the ground below. Dr Harvey has deliberately restricted his use of geological terminology in order to make the presentation clear and easy to understand. The geological principles are fully illustrated by drawings. The author has taught courses on this subject for twenty years. He has based the book on his teaching experiences and has written it primarily for engineering students taking a first course in rock and soil mechanics.

From the mysterious depths of Lake Vostok, Antarctica, to tropical floodplain lakes, inland seas, hydro-reservoirs and the variety of waterbodies in our local environment, lakes encompass a huge diversity of shapes, sizes, depths, colours, and even salinities. Often very large and very deep, they sustain important and unique ecosystems which can be hotspots of biodiversity, and are used by humans as sources of drinking water and food, in particular, fish. What is the origin of differences among lakes, and how does that affect the life within them? What are the seasons of a lake, and how do human actions alter lake ecosystems locally, and at a global scale? In this Very Short Introductions, Warwick Vincent outlines the essential features of lake environments and their biology, offering an up-to-date view of lake ecosystems. Vincent traces the origins of lake science (limnology) from the seminal work of Francois Forel on Lake Geneva at the edge of the Swiss Alps, to modern approaches such as environmental sensors, satellite observations, stable isotope analysis, and DNA-based technologies which are used to probe the microbial life support systems that lead from sunlight to fish. Drawing on varied case studies he considers the intimate relationship between humans and lakes, the value of lakes as indicators of environmental change, the impact of pollution,and our urgent need to improve the protection and management of these vitally important living resources via an integrated understanding of their ecology. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

In the Pacific Northwest, the river of dominance is the Columbia, and in ways both profound and mundane its history is the history of the region. In "Great River of the West" historians and anthropologists consider a range of topics about the river, from Indian rock art, Chinook Jargon, and ethnobotany on the Columbia to literary and family history, the creation of an engineered river, and the inherent mythic power of place.

Since first contact between Euro-Americans and Native peoples during the late 18th century, the river's history has been characterized by dramatic demographic, social, and economic changes. The remarkable set of essays in Great River of the West investigate these changes by highlighting important episodes in the history of the river. Readers meet mariners who challenge the Columbia River bar, a family torn by insanity, Native people who preserve fishing traditions, and dam-builders who radically change the Columbia.

The Thames Estuary is the gateway into London that had to be defended against seaborne invasion. Through proximity to the Continent, these waters were a likely passageway for those intent upon seaborne raids or invasion, necessitating the need for a powerful naval force to be on hand when threatened. The first fortifications date back to Roman times. To support the British navy in these waters, four of the nation’s royal dockyards – Chatham, Deptford, Sheerness and Woolwich – were clustered along the Thames Estuary or close by on the Medway from the sixteenth and seventeenth centuries for the commissioning, refitting and repair of warships. As well as being of importance for the defence of the country, the Thames Estuary fulfilled another role: that of underpinning naval activities designed to support British tactical and strategic operations in more distant parts of the world. Close to the mouth of the Thames, and near the point of confluence with the Medway, was the Nore, a key naval anchorage where newly commissioned warship assembled, taking on crews and receiving final instructions before joining the active seagoing fleet. In the twentieth century, additional defences against attack by submarine or from the air were established, and gunpowder factories sited along the estuary. This book will be of interest to all those who would like to know more about the remarkable military history of the Thames Estuary over the last 2,000 years.

Although of high abundance, diversity and ecological importance, meiofauna is little covered by relevant scientific media. How can this negligence be overcome? The present treatise highlights promising meiofauna research fields, selected both from basic and applied science, as well as new methods that could strengthen the potential of meiobenthology. Selected recent meiofauna studies, often supported by rapidly advancing gene-based methods, underline the relevance and potential of meiobenthology revealing characteristics and harassments of ecosystems, not the least in extreme habitats. Also in the more classical domains such as taxonomy and phylogeny, progress in meiobenthos research defines a new and deeper scientific understanding.

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.

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 have taught undergraduate hydrology courses for many years.

Second- and final-year undergraduate (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.

Reviews:

"This is a very well-written and wide-ranging volume that is both instructive and topical. It is likely to prove useful as an introduction to the general area, a reference source and for teaching purposes." ("The Holocene," November 2008)

"If you thought that paleolimnology was just mud, pollen, and diatoms then you will likely be both struck by the complexity of this field of research and grateful that John Smol, FRSC, has described it so clearly and broadly. Simply put, the second edition is an excellent book." "( Journal of Phycology, 2008)"

"This is a useful text. It provides a good level of detail so that the beginner in this area can appreciate what palaeolimnology can (and cannot) achieve. It goes beyond the simple introduction to provide a detailed understanding of how techniques can be applied ... This is a different take on the usual pollution text and would be of great use to those wishing to understand more from sedimentary records." "Taken from the British Ecological Society's Teaching Ecology website"

"John Smol has extensive experience in this field of paleoenvironmental research which he combines well with his excellent written communication skills to produce a text that is easy to read but also thought provoking." "(Quaternary Science Reviews, 2009)"

"The breadth of coverage in this text is impressive." "(Lake and Reservoir Management"," 2009)"

"If I could speak with fluidity and clarity in my lectures as consistently as John Smol writes my students would be very grateful." "(Journal of Paleolimnology, 2009)"

To understand hydrochemistry and to analyze natural as well as man-made impacts on aquatic systems, hydrogeochemical models have been used since the 1960's and more frequently in recent times. Numerical groundwater flow, transport, and geochemical models are important tools besides classical deterministic and analytical approaches. Solving complex linear or non-linear systems of equations, commonly with hundreds of unknown parameters, is a routine task for a PC. Modeling hydrogeochemical processes requires a detailed and accurate water analysis, as well as thermodynamic and kinetic data as input. Thermodynamic data, such as complex formation constants and solubility-products, are often provided as databases within the respective programs. However, the description of surface-controlled reactions (sorption, cation exchange, surface complexation) and kinetically controlled reactions requires additional input data. Unlike groundwater flow and transport models, thermodynamic models, in principal, do not need any calibration. However, considering surface-controlled or kinetically controlled reaction models might be subject to calibration. Typical problems for the application of geochemical models are: * speciation * determination of saturation indices * adjustment of equilibria/disequilibria for minerals or gases * mixing of different waters * modeling the effects of temperature * stoichiometric reactions (e.g. titration) * reactions with solids, fluids, and gaseous phases (in open and closed systems) * sorption (cation exchange, surface complexation) * inverse modeling * kinetically controlled reactions * reactive transport Hydrogeochemical models depend on the quality of the chemical analysis, the boundary conditions presumed by the program, theoretical concepts (e.g.

In the name of agriculture, urban growth, and disease control, humans have drained, filled, or otherwise destroyed nearly 87 percent of the world's wetlands over the past three centuries. Unintended consequences include biodiversity loss, poor water quality, and the erosion of cultural sites, and only in the past few decades have wetlands been widely recognized as worth preserving. Emily O'Gorman asks, What has counted as a wetland, for whom, and with what consequences? Using the Murray-Darling Basin-a massive river system in eastern Australia that includes over 30,000 wetland areas-as a case study and drawing on archival research and original interviews, O'Gorman examines how people and animals have shaped wetlands from the late nineteenth century to today. She illuminates deeper dynamics by relating how Aboriginal peoples acted then and now as custodians of the landscape, despite the policies of the Australian government; how the movements of water birds affected farmers; and how mosquitoes have defied efforts to fully understand, let alone control, them. Situating the region's history within global environmental humanities conversations, O'Gorman argues that we need to understand wetlands as socioecological landscapes in order to create new kinds of relationships with and futures for these places.

Whilst a large number of foreign and state initiated water management systems have failed for various reasons, locally developed water harvesting systems have proven their viability by surviving for hundreds of years. Whilst there has to be some recognition of the geographical limits and some questions asked about the quality of these water supplies, even with these detractors accounted for these systems often remain superior to those imposed by political and private interests, not only in terms of their reliability, but also in terms of their flexibility and more equitable control.This book aims to offer a closer look at local flexible strategies for securing water resources under demanding climatic conditions and during environmental changes. The research dealt with here aims to identify a range of initiatives that have been created by and for members of indigenous communities to address such challenges, such as traditional structures for collecting run-off and rainwater. It poses the questions: How have these strategies been formed and made to operate? What positive and negative lessons can be learned from the interplay between local knowledge, subsistence strategies, and the influx of knowledge and initiatives from the outside?As well as describing the function and social significance of water harvesting systems, a further aim of this book is to highlight the wider political and economic context of local knowledge about water harvesting and its uses, and the impact of contrasting management strategies on social development in the local communities involved. Water harvesting and irrigation systems form an important part of the vast knowledge that indigenous and local populations have of their natural environment. Such knowledge is embedded within complex social organisations, and forms the basis of both formal and important non-formal social networks. Indeed, together with the management of land, the management of water resources frequently provides the basis of social institutions and relationships to which ideas of belonging and community membership are tied.Indeed, water resources, along with other natural resources, comprise not only a vital element of subsistence, but also a vital field of social and political inter-action and practice.

Why do fish jump? Why don't lakes freeze all the way down to the bottom? Which lake plants are invasive? What are those water bugs? Is that lake healthy? Whether you fish, paddle, swim, snowshoe, ski, or just gaze upon your favorite lake, A Lakeside Companion will deepen your appreciation for the forces that shape lakes and the teeming life in and around them. You'll discover the interconnected worlds of a lake: the water; the sand, gravel, rocks, and muck of the bottom; the surface of the lake; the air above; and the shoreline, a belt of land incredibly rich in flora and fauna. Explained, too, are the physical, biological, and chemical processes that determine how many and what kinds of fish live in the lake, which plants grow there, the color and clarity of the water, how ice forms in winter and melts in spring, and much more. Useful advice will help you look out for your lake and advocate for its protection.
