Landslides are a constant in shaping our landscape. Whether by large episodic, or smaller chronic, mass movements, our mountains, hills, valleys, rivers, and streams bear evidence of change from landslides. Combined with anthropogenic factors, especially the development and settlement of unstable terrain, landslides (as natural processes) have become natural disasters.This book charts our understanding of landslide processes, prediction methods, and related land use issues. How and where do landslides initiate? What are the human and economic consequences? What hazard assessment and prediction methods are available, and how well do they work? How does land use, from timber harvesting and road building to urban and industrial development, affect landslide distribution in time and space? And what is the effect of land use and climate change on landslides?This book responds to such questions with: - Synopses of how various land uses and management activities influence landslide behavior- Analyses of earth surface processes that affect landslide frequency and extent- Examples of prediction techniques and methods of landslide hazard assessment, including scales of application- Discussion of landslide types and related costs and damagesThose who study landslides, and those who deal with landslides, from onset to after-effects--including researchers, engineers, land managers, educators, students, and policy makers--will find this work a benchmark reference, now and for years to come.

BL A practical teaching course BL Takes an environmental approach to hydrology This is a textbook in environmental hydrology DSa field of study concerned with the basic system of water circulation and patters of runoff and the major ways in which human occupation of Earth alters both processes and pattersn. It focuses on the river basin or catchment unit not only because of its geographical appeal but because it is the basic experimental and data-gathering unit, and the fundamental unit for water management. The book explores a considerable number of methodological frameworks. Most of these are scientific; an acceptable replacement for problem-solving by data collection, analysis, and prediction has yet to be found. However, it also considers non-digital values DSattitudes, preferences, policies, laws DSespecially in the case of the freshwater environment, where key data are still relatively scarce. Having developed a holistic approach to river basins, the author concludes by considering the utility of our current knowledge of environment hydrology to provide the reader with a practical response to the conservation of fresh water. This book is intended for second and third year und

In this thoroughly updated third edition, the authors provide a series of carefully designed and tested field and laboratory exercises that represent the full scope of limnology. In using the text, students will gain a solid foundation in this complex, multidisciplinary field of ecology as they explore the physical, chemical, and biological characteristics of standing and running waters. The book illustrates accepted standard methods as well as modern metabolic and experimental approaches and their research applications. Each exercise is preceded by an introductory section and concludes with questions for students as well as suggestions for further reading. As a textbook, this is a highly structured, concise presentation with a research-oriented approach that openly invites active participation by students.

‘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.

Aquatic ecosystems have formed the focus of several UNESCO research projects because of the impact on them of human activities such as intensification of agricultural activity, erosion and sedimentation due to irrigation projects, groundwater pollution and eutrophication. Interfaces, or ecotones, between terrestrial and aquatic ecosystems were found to have an essential role in the movement of water and materials throughout the landscape. Ecotones are zones where ecological processes are more intense and resources more diversified. They are also zones which react quickly to human influences and changes of environmental variables. This volume summarises the results presented at an international conference dedicated to the study of groundwater/surface water ecotones, with contributors of international scientific reputation representing the multidisciplinary viewpoints of hydrologists, biologists and ecologists. It addresses areas of active research in hydrology and biology, and is aimed towards researchers, water resource project managers and policy makers.

Freshwater is a valuable resource for human populations, and has many uses such as water for drinking, hydroelectric power and recreation. This creates conflict between conservation and exploitation. This book explores various aspects of conservation evaluation, including the selection of important areas for protection, responding to threats from catchment development, and determining the restoration potential of degraded water bodies. Aimed at academic researchers, graduate students and professionals, chapters are written by pairs of UK and US authors, who compare methods used for evaluating rivers and lakes for conservation in these countries who share a long history of freshwater science, but approach nature conservation very differently. Sweden, Australia and South Africa are also examined, and there is a chapter on developing countries, allowing examination of the role of social and economic conditions in conservation ethics.

Water resources professionals have an obligation to conceive and manage water resource systems such that they will fully contribute to an improved quality of life for all humans, now and into the future. Those water resource systems that will be able to satisfy the changing demands that will inevitably be placed on them, without significant system degradation, can be called 'sustainable'. An international group of experts have reviewed various guidelines for achieving greater degrees of sustainability and the extent to which they have been applied in a number of case studies. Approaches for measuring and modelling sustainability are provided. Ways in which these measures and models might be used when evaluating alternative designs and operating policies are illustrated. The monograph will be particularly valuable for practising engineers and planners, and as a supplementary text for graduate students in civil and environmental engineering, hydrology, geography and economics.

Whether processes in the natural world are dependent or independent of the scale at which they operate is one of the major issues in hydrologic science. In this volume, leading hydrologists present their views on the role of scale effects in hydrologic phenomena occurring in a range of field settings, from the land surface to deep fractured rock. Self-contained and thought-provoking chapters cover both theoretical and applied hydrology. They provide critical insights into important topics such as general circulation models, floods, river networks, vadose zone processes, groundwater transport, and fluid flow through fractured media. This book is intended as an accessible introduction for graduate students and researchers to some of the most significant questions and challenges that will face hydrologic science in the twenty-first century.

Completely updated, the second edition of this comprehensive volume not only covers all major areas of hydrogeology, it takes a process-oriented, integrated approach so that readers can gain a complete understanding of the relationship between physical and chemical aspects of this subject. Provides a good balance between theory and application and includes new areas such as contaminant hydrogeology. Includes extensive reference list and suggested readings.

Rivers differ among themselves and through time. An individual river can vary significantly downstream, changing its dimensions and pattern dramatically over a short distance. If hydrology and hydraulics were the primary controls on the morphology and behaviour of large rivers, we would expect long reaches of rivers to maintain characteristic and relatively uniform morphologies. In fact, this is not the case - the variability of large rivers indicates that other important factors are involved. River Variability and Complexity presents an interesting approach to the understanding of river variability. It provides examples of river variability and explains the reasons for them, including fluvial response to human activities. Understanding the mechanisms of variability is important for geomorphologists, geologists, river engineers and sedimentologists as they attempt to interpret ancient fluvial deposits or anticipate river behaviour at different locations and through time. This book provides an excellent background for graduates, researchers and professionals.

This concise, readable introduction to limnology (the science of investigating the structure and function of inland waters), places the subject in the context of modern ecology. Unlike most ecological textbooks, which use examples taken almost exclusively from terrestrial systems, this book integrates the fields of limnology and ecology by presenting empirical data drawn entirely from freshwater ecosystems in order to advance ecological theories (limnoecology).
This second edition builds upon the strengths of the first with the structure of the book following the same hierarchical concept of ecology, from habitat properties, individuals, populations, coupled populations and communities to ecosystems. However, it has been thoroughly revised throughout to incorporate findings from new technologies and methods (notably the rapid development of molecular genetic methods and stable isotope techniques) that have allowed a rapid and ongoing development of the field. There is a new emphasis on food webs, species diversity and ecosystem functioning, climate change, and conservation management. Key ecological questions are examined in the light of the latest experimental evidence. Throughout the text evolutionary theory is applied to an understanding of freshwater ecosystems, thereby filling a niche between traditional limnology and evolutionary ecology.
This accessible text is suitable for both undergraduate and graduate students taking courses in limnology, freshwater ecology, and aquatic biology as well as the many professional limnologists, ecologists and conservation biologists requiring a concise but authoritative overview of the topic.

One of the greatest problems hydrology research faces is how to quantify uncertainty, which is inherent in every hydrological process. This overview of uncertainty emphasizes non-orthodox concepts, such as random fields, fractals and fuzziness. This book reviews alternative and conventional methods of risk and uncertainty representation in hydrology and water resources. The water-related applications discussed in the book pertain to areas of strong interest, such as multifractals and climate change impacts. The authors represent a variety of research backgrounds, achieving a broad subject coverage. The material covered provides an important insight into theories of uncertainty related to the field of hydrology. The book is international in its scope, and will be welcomed by researchers and graduate students of hydrology and water resources.

Ecohydrology of Water-Controlled Ecosystems addresses the connections between the hydrologic cycle and plant ecosystems, with special emphasis on arid and semi-arid climates. This important topic is treated by building suitable mathematical models of the physics involved and then applying them to study the ecosystem structure and its response to rainfall and climate forcing in different parts of the world, including savannas, grasslands and forests. It investigates the vegetation response to water stress (drought), the hydrologic control on cycles of soil nutrients, and the dynamics of plant competition for water. The book also offers insights into processes closely related to soil moisture dynamics, such as soil-atmosphere interaction and soil gas emissions. This book will appeal to advanced students and researchers from a large range of disciplines, including environmental science, hydrology, ecology, earth science, civil and environmental engineering, agriculture and atmospheric science.

Risk, Reliability, Uncertainty, and Robustness of Water Resource Systems is based on the Third George Kovacs Colloquium organized by the International Hydrological Programme (UNESCO) and the International Association of Hydrological Sciences. Thirty-five leading scientists with international reputations provide reviews of topical areas of research on water resource systems, including aspects of extreme hydrological events: floods and droughts; water quantity and quality dams; reservoirs and hydraulic structures; evaluating sustainability and climate change impacts. As well as discussing essential challenges and research directions, the book will assist in applying theoretical methods to the solution of practical problems in water resources. The authors are multi-disciplinary, stemming from such areas as: hydrology, geography, civil, environmental and agricultural engineering, forestry, systems sciences, operations research, mathematics, physics and geophysics, ecology and atmospheric sciences. This review volume will be valuable for graduate students, scientists, consultants, administrators, and practising hydrologists and water managers.

This introductory 2004 textbook describes the nature of the Earth's environment and its physical processes so as to highlight environmental concerns arising from human use and misuse of soil and water resources. The author provides a thorough introduction to the basic issues regarding the sustainable, productive use of land resources that is vital in maintaining healthy rivers and good groundwater qualities. He develops a quantitative approach to studying these growing environmental concerns in a way that does not require prior knowledge of the physical sciences or calculus. The straightforward writing style, lack of prerequisite knowledge and copious illustrations make this textbook suitable for introductory university courses, as well as being a useful primer for research and management staff in environmental and resources management organisations. Each chapter ends with a set of student exercises for which solutions are available from [email protected].
