Each chapter in the book has been specifically commissioned to represent areas in which recent progress has been made in the field. The topics covered also represent a coherent progression through the principal areas of the subject (hydraulics; sediment transport; river morphology; tools and methods; applications of science). Definitive review of the current knowledge of gravel-bed rivers Coverage of both fundamental and applied topics Edited by leading academics with contributions from key researchers Thoroughly edited for quality and consistency to provide coherent and logical progression through the principal areas of the subject.

"Read what over 60 internationally recognized authors say about fluvial processes, the environment, and management of gravel-bed rivers. Learn about efforts to restore more-natural ecosystem functions to adversely impacted rivers. And for some mind-stretching, consider the hydraulic/geomorphic implications of cataclysmic floods on Earth and Mars. Beginning in 1980 and held at five-year intervals, these workshops have brought together leading international researchers to present and discuss new results, concepts and state-of-the-art methods to analyze fluvial processes in and manage gravel-bed rivers. The fourth workshop was held at Gold Bar, Washington, near the dynamic Skykomish River and strikingly beautiful Cascade Mountains. Workshop papers and discussions are published to document new concepts and ideas for broad use by those who study, manage or have general interests in rivers. This fourth Gravel-Bed Rivers Workshop covers three focus topics. The first topic reviews new developments regarding fluvial processes, sediment transport and channel morphology -- in eight chapters on distinct subjects. The second and third focus topics strongly emphasize gravel-beds rivers in the environment, their influences, and their management -- in the next 19 chapters. River restoration is examined for large European and North American rivers as parts of several of the environment-management chapters. Seven appended "short papers" report on research in progress, presented at the Workshop in a poster-discussion session. Also included are two special-interest chapters -- on giving a detailed analysis and morphologic/hydraulic interpretation of cataclysmic floods and one summarizing a field exercise in management options for a long braided-meandering reach of the Skykomish River near Gold Bar."--Publisher's description.

Based on the interdisciplinary approaches between earth science, engineering, physical geography, ecology and management, this text focuses on the theoretical questions, case-studies, challenges, and constraints taken from river restoration. It is illustrated with reports of new ground-breaking research covering spatial and temporal scales of physical processes in river catchments, coupling catchment and fluvial processes, grain dynamics and fluvial forms and on geo-ecology and restoration in mountain gravel-bed river environments. Each chapter includes discussions and comments providing experience and feedback from the fundamental research. This book covers scales of analysis for gravel-bed rivers, physics and modeling of processes at local and point scales, sediment delivery and storage, eco-geography and eco-hydraulics, and channel management and restoration. * Major topics in the field are presented by recognized scientific leaders * Chapters cover theories, practices, and methodologies in river management and restoration * Interdisciplinary approach includes case-studies on new, ground-breaking research

The heightened interest in gravel-bed rivers among scientists and engineers has been spurred by recent industrial utilization of water resources and forests in upland areas, as well as developmenat of these lands for recreational use. This book describes and quantifies the movement and storage of sediment in rivers with gravel-bed material based upon scientific and engineering principles. The material includes a selection of papers presented at a recent symposium, along with several discussions which develop and broaden coverage. Topics cover both theory and experimental findings, plus several case studies.

It is surprising that gravel-bed rivers meander. In laboratory settings using cohesionless sediment transported as bedload, braiding inevitably emerges. The easily entrained outer bank sediments lead to relatively rapid bank erosion, the inner bank bar reaches it shallowest depth towards the center of the channel, the flow diverges, and braiding arises. These observations have led to the inference that meandering requires some bank strength to slow outer bank erosion and allow the inner bank to keep pace with outer bank retreat. Commonly it has been suggested that vegetation can provide that outer bank strength. While this view has led recently to numerical modeling incorporating vegetation strength, no studies had successfully created meandering rivers in the laboratory such that controlling mechanisms could be explored. Nor has there been an effort to delineate under what general conditions gravel bedded meanders are found in the field. These knowledge gaps are particularly important to stream restoration work because the creation of morphologically-stable gravel-bedded meanders is a common goal. This dissertation uses flume experiments and a compilation of field data to explore the conditions that support meandering in gravel-bed rivers. Using alfalfa sprouts as model vegetation, sand as scaled-down gravel, and a lightweight plastic as scaled-down sand, I created for the first time a self-maintaining, laterally migrating meandering river with cutoff loops in a 6.1-m wide, 17-m long laboratory flume. The channel, 0.4 m wide, had a sinuosity of 1.1-1.2 and transported sediment with a median size of 0.78 mm. The sinuosity of the channel increased as bends grew, decreased as the channel cut off, and was regenerated while the channel maintained a steady width. In this experiment, we found that a steady bankfull flow was sufficient to sustain a meandering planform, and that application of higher peak flows caused the channel to widen because bank erosion outpaced bar growth. Coarse sediment was exchanged between eroding banks and the next bar downstream with little net downstream flux, consequently to prevent aggradation and avulsion at the upstream end of the experimental reach required turning off the coarse sediment feed. The input of fine sediment was crucial for blocking chute channels (a locus for braiding), filling point bars downstream of the bend apex, and plugging abandoned channels following cutoff. Hence, sustained growth of bends and development of meandering requires more than just sufficient bank strength to slow the outer bank erosion rate. A compilation of 166 gravel-bedded meanders from the literature shows that gravel meanders primarily occur in lower gradient reaches extending from mountain ranges, high-elevation valleys, and in humid areas influenced by glaciation or glacio-fluvial outwash. Unexpectedly, analysis of Google Earth imagery showed that about 1/3 of the dataset lacked cutoff scars and other evidence of active migration. Gravel bedded meanders with median surface grain size> 10 mm had low Shields stress, particularly for meanders with cutoffs and without islands. Gravel bedded meanders with median surface grain sizes
