David Knighton's best-selling book looks at the wide range of forms developed by natural rivers and the processes responsible for that development. The book combines empirical and theoretical approaches, and provides a critical assessment of the many schools of thought which have emerged for dealing with adjustment in the fluvial system. It is fully illustrated throughout by a superb range of figures, photographs and tables. Starting with the network scale, the book examines the interaction of hillslopes, drainage networks and channels, and goes on to considerations of catchment hydrology and catchment denudation. Fluvial processes are analysed in detail, from the mechanics of flow to sediment transport and deposition. Detailing the major components of river channels, the book examines the nature of river adjustment, particularly with respect to equilibrium concepts, and concludes with a look at channel changes through time, affected by flood discharges, climatic change and human activities.

This volume provides a comprehensive perspective on geomorphic approaches to management of lowland alluvial rivers in North America and Europe. Many lowland rivers have been heavily managed for flood control and navigation for decades or centuries, resulting in engineered channels and embanked floodplains with substantially altered sediment loads and geomorphic processes. Over the past decade, floodplain management of many lowland rivers has taken on new importance because of concerns about the potential for global environmental change to alter floodplain processes, necessitating revised management strategies that minimize flood risk while enhancing environmental attributes of floodplains influenced by local embankments and upstream dams. Recognition of the failure of old perspectives on river management and the need to enhance environmental sustainability has stimulated a new approach to river management. The manner that river restoration and integrated management are implemented, however, requires a case study approach that takes into account the impact of historic human impacts to the system, especially engineering. The river basins examined in this volume provide a representative coverage of the drainage of North America and Europe, taking into account a range of climatic and physiographic provinces. They include the 1) Sacramento (California, USA), 2) San Joaquin (California), 3) Missouri (Missouri, USA), 4) Red (Manitoba, Canada and Minnesota, USA), 5) Mississippi (Louisiana, USA), 6) Kissimmee (Florida, USA), 7) Ebro (Spain), 8) Rhone (France), 9) Rhine (Netherlands), 10) Danube (Romania), and 11) Volga (Russian Federation) Rivers. The case studies covered in these chapters span a range of fluvial modes of adjustment, including sediment, channel, hydrologic regime, floodplains, as well as ecosystem and environmental associations.

Fluvial Geomorphology studies the biophysical processes acting in rivers, and the sediment patterns and landforms resulting from them. It is a discipline of synthesis, with roots in geology, geography, and river engineering, and with strong interactions with allied fields such as ecology, engineering and landscape architecture. This book comprehensively reviews tools used in fluvial geomorphology, at a level suitable to guide the selection of research methods for a given question. Presenting an integrated approach to the interdisciplinary nature of the subject, it provides guidance for researchers and professionals on the tools available to answer questions on river restoration and management. Thoroughly updated since the first edition in 2003 by experts in their subfields, the book presents state-of-the-art tools that have revolutionized fluvial geomorphology in recent decades, such as physical and numerical modelling, remote sensing and GIS, new field techniques, advances in dating, tracking and sourcing, statistical approaches as well as more traditional methods such as the systems framework, stratigraphic analysis, form and flow characterisation and historical analysis. This book: Covers five main types of geomorphological questions and their associated tools: historical framework; spatial framework; chemical, physical and biological methods; analysis of processes and forms; and future understanding framework. Provides guidance on advantages and limitations of different tools for different applications, data sources, equipment and supplies needed, and case studies illustrating their application in an integrated perspective. It is an essential resource for researchers and professional geomorphologists, hydrologists, geologists, engineers, planners, and ecologists concerned with river management, conservation and restoration. It is a useful supplementary textbook for upper level undergraduate and graduate courses in Geography, Geology, Environmental Science, Civil and Environmental Engineering, and interdisciplinary courses in river management and restoration.

This book is the fourth volume in the definitive series, The History of the Study of Landforms or The Development of Geomorphology. Volume 1 (1964) dealt with contributions to the field up to 1890. Volume 2 (1973) dealt with the concepts and contributions of William Morris Davis. Volume 3 (1991) covered historical and regional themes during the 'classic' period of geomorphology, between 1980 and 1950. This volume concentrates on studies of geomorphological processes and Quaternary geomorphology, carrying on these themes into the second part of the twentieth century, since when process-based studies have become so dominant. It is divided into five sections. After chapters dealing with geological controls, there are three sections dealing with process and form: fluvial, glacial and other process domains. The final section covers the mid-century revolution, anticipating the onset of quantitative studies and dating techniques. The volume's objective is to describe and analyse many of the developments that provide a foundation for the rich and varied subject matter of contemporary geomorphology. The volume is in part a celebration of the late Professor Richard Chorley, who devised its structure and contributed a chapter.

Rivers and Floodplains is concerned with the origin, geometry, water flow, sediment transport, erosion and deposition associated with modern alluvial rivers and floodplains, how they vary in time and space, and how this information is used to interpret deposits of ancient rivers and floodplains. There is specific reference to the types and lifestyles of organisms associated with fluvial environments, human interactions with rivers and floodplains, associated environmental and engineering concerns, as well as the economic aspects of fluvial deposits, particularly the modeling of fluvial hydrocarbon reservoirs and aquifers. Methods of studying rivers and floodplains and their deposits are also discussed. Although basic principles are emphasized, many examples are detailed. Particular emphasis is placed on how an understanding of the nature of modern rivers and floodplains is required before any problems concerning rivers and floodplains, past or present, can be addressed rationally. Rivers and Floodplains is designed as a core text for senior undergraduate and graduate students studying modern or ancient fluvial environments, particularly in earth sciences, environmental sciences and physical geography, but also in civil and agricultural engineering. College teachers, researchers, and practising professionals will also find the book an invaluable reference. Presents a process-based approach, which is relevant to modern curricula. Discusses methods of studying rivers and floodplains and their deposits. Provides many detailed examples throughout the text. Emphasises the basic principles of this subject. As the first synthesis of this entire field, it will be a must-have for all students studying modern or ancient fluvial environments. Teachers, researchers and practising professionals will find this an invaluable reference tool. Rivers and Floodplains will also be of interest to geologists, geographers and engineers.

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.

Periglacial and paraglacial environments, located outside ice sheet margins but responding to similar climate forcings, are key to identifying climate change effects upon the Earth system. These environments are relicts of cold Earth processes and so are most sensitive to global warming. Changes in the distribution and thickness of permafrost in continental interiors have implications for ecosystem and landscape stability. Periglacial Alpine environments are experiencing increased rockfall and mass movement, leading to rock glacier instability and sediment release to downstream rivers. In turn, these landscape effects impact on natural hazards and human activities in these sensitive and geologically transient environments.

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.

This invaluable overview of fluvial geomorphology provides river engineers and managers, who may lack specialist training, with useful insights into, and understanding of, natural channel forms and fluvial processes.Such information is a pre-requisite for carrying out environmental impact assessments and for developing environmentally sensitive design and management procedures to preserve riverine environments and restore degraded ones. Designing with nature is preferable to imposing hard engineering solutions as it sustains natural biodiversity and minimises costs. This book will also be a very useful teaching aid for students, both under- and post-graduate, studying civil engineering, environmental management or sciences, or geography who are looking to have a wider knowledge of new approaches to the subject.Geomorphology requires the collection and consideration of a wide range of data, mostly field based but also including historical information such as archive documents and maps, which are outside the experience of most river engineers and managers. These data enable the current condition of the river to be explained, both locally and within the catchment, and establish historical changes and future trends. In addition, process studies have now identified many of the mechanisms controlling river moprhology which underpin the development of soft, bio-engineering, design procedures. The book incorporates material on methods and techniques of data collection, analysis and interpretation, making extensive use of case studies throughout.Thus the experienced authors go some way towards demystifying applied fluvial geomorphology by demonstrating that, while there is still an element of judgement, major contributions to geomorphic understanding usually come from the careful assemblage and objective analysis of all available data and information.

The Norwegian Continental Shelf (NCS), focus of this special publication, is a prolific hydrocarbon region and both exploration and production activity remains high to this day with a positive production outlook. A key element today and in the future is to couple technological developments to improving our understanding of specific geological situations. The theme of the publication reflects the immense efforts made by all industry operators and their academic partners on the NCS to understand in detail the structural setting, sedimentology and stratigraphy of the hydrocarbon bearing units and their source and seal. The papers cover a wide spectrum of depositional environments ranging from alluvial fans to deepwater fans, in almost every climate type from arid through humid to glacial, and in a variety of tectonic settings. Special attention is given to the integration of both analogue studies and process-based models with the insights gained from extensive subsurface datasets.
