Changing River Channels is intended for all those with an interest in the dynamics of river channels and their management. Contributions are drawn from both the academic and river management communities and these provide perspectives based upon British, European and North American examples. The chapters are organised into four sections which consider the magnitude and dimensions of river channel adjustments over different timescales; the processes which influence those adjustments, focussing particularly upon the roles of sediment transport and storage, and of vegetation; the information sources that are available for assessing the degree and nature of change; and finally, perspectives on the management of changing river channels. This volume is one of two companion edited books to mark the contributions of Professors K.J. Gregory and D. E. Walling to research on drainage basin form and processes. Each presents a balanced range of contributions written by research colleagues and students.

River Channel Management is the first book to deal comprehensively with recent revolutions in river channel management. It explores the multi-disciplinary nature of river channel management in relation to modern management techniques that bear the background of the entire drainage basin in mind, use channel restoration where appropriate, and are designed to be sustainable. River Channel Management is divided into five sections: ·The Introduction outlines the need for river channel management . ·Retrospective Review offers an overview of twentieth century engineering methods and the ways that river channel systems operate. ·Realisation explains how greater understanding of river channel adjustments, channel hazards and river basin planning created a context for twenty-first century management. ·Requirements for Management explains and examines environmental assessment, restoration-based approaches, and methods that work towards 'design with nature' ·Final Revision speculates about prospects for twenty-first century river channel management. River Channel Management is written for higher-level undergraduates and for postgraduates in geography, ecology, engineering, planning, geology and environmental science, for professionals involved in river channel management, and for staff in environmental agencies.

River Science is a rapidly developing interdisciplinary field at the interface of the natural sciences, engineering and socio-political sciences. It recognises that the sustainable management of contemporary rivers will increasingly require new ways of characterising them to enable engagement with the diverse range of stakeholders. This volume represents the outcome of research by many of the authors and their colleagues over the last 40 years and demonstrates the integral role that River Science now plays in underpinning our understanding of the functioning of natural ecosystems, and how societal demands and historic changes have affected these systems. The book will inform academics, policy makers and society in general of the benefits of healthy functioning riverine systems, and will increase awareness of the wide range of ecosystem goods and services they provide.

Rivers are significant geomorphological agents, they show an amazing diversity of form and behaviour and transfer water and sediment from the land surface to the oceans. This book examines how river systems respond to environmental change and why this understanding is needed for successful river management. Highly dynamic in nature, river channels adjust and evolve over timescales that range from hours to tens of thousands of years or more, and are found in a wide range of environments. This book provides a comprehensive overview of recent developments in river channel management, clearly illustrating why an understanding of fluvial geomorphology is vital in channel preservation, environmentally sensitive design and the restoration of degraded river channels. It covers: flow and sediment regimes: flow generation; flow regimes; sediment sources, transfer and yield channel processes: flow characteristics; processes of erosion and sediment transport; interactions between flow and the channel boundary; deposition channel form and behaviour: controls on channel form; channel adjustments; floodplain development; form and behaviour of alluvial and bedrock channels response to change: how channels have responded to past environmental change; impacts of human activity; reconstructing past changes river management: the fluvial hydrosystem; environmental degradation; environmentally sensitive engineering techniques; river restoration; the role of the fluvial geomorphologist. Fundamentals of Fluvial Geomorphology is an indispensable text for undergraduate students. It provides straightforward explanations for important concepts and mathematical formulae, backed up with conceptual diagrams and appropriate examples from around the world to show what they actually mean and why they are important. A colour plate section also shows spectacular examples of fluvial diversity.

This book evolved from a collaborative research project between the University of Manitoba, Canada and Jahangirnagar University, Bangladesh, which commenced in 1984 to study the problems of river channel migration, rural population displacement and land relocation in Bangladesh. The study was sponsored by the International Development Research Center (IDRC), based in Ottawa, Canada. It was through this project that I started my journey into disaster research more than thirteen years ago with basically an applied problem of massive magnitude in Bangladesh. I spent two- and-a half-years, in two stages, in Bangladesh's riparian villages to collect the empirical data for this study. Then the growing disaster discourse throughout the 1980s, especially its conceptual and theoretical areas, drew me in further, gluing my interest to these issues. In the 1990s, during my research and teaching at Brandon University, Canada, I realized that, despite the large body of literature on natural disasters, there was no work that synthesized the approaches to nature-triggered disasters in a comprehensive form, with sufficient empirical substantiation. In addition, despite the great deal of attention given to disasters in Bangladesh, I found no detailed reference book on the topic. Natural hazards and disasters, in my view, should be studied under a holistic framework encompassing the natural environment, society and individuals. Overreaction to the limitations of technocratic-scientific approaches-the control and prevention of physical events through specialized knowledge and skills-has resulted in a call for "taking the naturalness out of natural disasters.

Incised river channels are ubiquitous features of landscapes disturbed by environmental change. Problems associated with channel incision include undermining of structures, downstream sedimentation, severe bank erosion and widening, and degradation of aquatic and riparian habitats. In Incised River Channels, research from the disciplines of geomorphology, hydraulics, sediment transport, ecology, environmental management and river engineering is brought together to develop a detailed, integrated treatment, over a range of spatial and temporal scales, of the dynamic behaviour of unstable incised rivers. The book emphasizes the need for improved understanding of the processes and mechanisms of channel adjustment and evolution to underpin sustainable river management and engineering. It contains important original contributions from an international authorship. Contributors include university and government scientists and researchers, as well as practitioners from regulatory and consultancy organizations. Divided into three thematic sections, Incised River Channels covers the nature and significance of incised channels, processes, and mitigation and management. Fundamental principles are illustrated using case studies from a wide range of physiographic environments, providing a wide geographical coverage. This volume will be of interest to academics and advanced level students who are studying fluvial geomorphology and/or river engineering. It will also be of appeal to all those interested in river adjustment and management.

California Rivers and Streams provides a clear and informative overview of the physical and biological processes that shape California's rivers and watersheds. Jeffrey Mount introduces relevant basic principles of hydrology and geomorphology and applies them to an understanding of the differences in character of the state's many rivers. He then builds on this foundation by evaluating the impact on waterways of different land use practices—logging, mining, agriculture, flood control, urbanization, and water supply development. Water may be one of California's most valuable resources, but it is far from being one we control. In spite of channels, levees, lines and dams, the state's rivers still frequently flood, with devastating results. Almost all the rivers in California are dammed or diverted; with the booming population, there will be pressure for more intervention. Mount argues that Californians know little about how their rivers work and, more importantly, how and why land-use practices impact rivers. The forceful reconfiguration and redistribution of the rivers has already brought the state to a critical crossroads. California Rivers and Streams forces us to reevaluate our use of the state's rivers and offers a foundation for participating in the heated debates about their future.

The first atomic bombs were constructed at the Los Alamos National Laboratory, where lab workers disposed of waste plutonium in nearby canyons leading to the Rio Grande. Today, the environmental consequences are just beginning to be understood as scientists examine the effects created by past mishandling of one of the most toxic chemical wastes known. Written in an engaging, accessible style, Plutonium and the Rio Grande is the first book to offer a complete exploration of this environmental history. It includes an explanation of what plutonium is, how much of it was released by the Los Alamos workers, and how much entered the river system directly from waste disposal and indirectly, as a result of atomic bomb fallout. The book includes extensive appendices, maps, diagrams, and photographs. Environmental managers, ecologists, hydrologists and other river specialists, as well as concerned general readers will find the book readable and informative.
