Gravel-Bed Rivers


Book Description

With contributions from key researchers across the globe, and edited by internationally recognized leading academics, Gravel-bed Rivers: Processes and Disasters presents the definitive review of current knowledge of gravel-bed rivers. Continuing an established and successful series of scholarly reports, this book consists of the papers presented at the 8th International Gravel-bed Rivers Workshop. Focusing on all the recent progress that has been made in the field, subjects covered include flow, physical modeling, sediment transport theory, techniques and instrumentation, morphodynamics and ecological topics, with special attention given to aspects of disasters relevant to sediment supply and integrated river management. This up-to-date compendium is essential reading for geomorphologists, river engineers and ecologists, river managers, fluvial sedimentologists and advanced students in these fields.




Sediment Transport in Gravel-Bed Rivers


Book Description

Describes and quantifies the movement and storage of sediment in rivers with gravel-bed material, based upon scientific and engineering principles. Papers based on theory and experiment are interspersed with case studies. Until recently, gravel-bed rivers have been under-researched, when compared with sand-bed rivers. There is a heightened interest in these rivers now, due to pressure from water resources, forestry and recreational development in upland areas.




Dynamics of Gravel-bed Rivers


Book Description

Contains articles by leading international experts in their respective fields. Papers are grouped into 17 topics that cover fundamental and applied issues involving the considerable progress made on sediment transport dynamics. Recent research provides insights into subjects such as selective entrainment, equal mobility, armouring processes, transport of fine material, mathematical sediment transport and morphological models as well as the impact of engineering works and catchment development projects on channel stability.




Sediment Cascades


Book Description

Sediment Cascades: An Integrated Approach provides a comprehensive overview that addresses the transport of sediment through the landscape. Suitable for academic researchers, industry practitioners, research students and advanced level undergraduates, seeking detailed knowledge and an up-to-date review of the recent research literature. The emphasis is on contemporary sediment system dynamics with relevance both to landscape management and landform development. Sediment Cascades: An Integrated Approach begins with an explanation of the need for an integrated approach to sediment delivery systems and introduces the main themes of sediment production, delivery, storage and transfer. Further chapters then focus on specific environments from mountains, through floodplains, to estuaries and the continental shelf. Focuses on contemporary sediment system dynamics and current research Covers a sequence of environments from steep mountains to the continental shelf Highlights the continuity of the subject by linking each component area with its adjacent elements




River Dynamics


Book Description

Rivers are important agents of change that shape the Earth's surface and evolve through time in response to fluctuations in climate and other environmental conditions. They are fundamental in landscape development, and essential for water supply, irrigation, and transportation. This book provides a comprehensive overview of the geomorphological processes that shape rivers and that produce change in the form of rivers. It explores how the dynamics of rivers are being affected by anthropogenic change, including climate change, dam construction, and modification of rivers for flood control and land drainage. It discusses how concern about environmental degradation of rivers has led to the emergence of management strategies to restore and naturalize these systems, and how river management techniques work best when coordinated with the natural dynamics of rivers. This textbook provides an excellent resource for students, researchers, and professionals in fluvial geomorphology, hydrology, river science, and environmental policy.







Gravel-bed Rivers in the Environment


Book Description

"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.




Guidelines for Using Bedload Traps in Coarse-bedded Mountain Streams


Book Description

A bedload trap is a portable sampler designed specifically for collecting gravel and cobble bedload (4 to 180 mm in diameter) in wadeable streams. Bedload traps consist of an aluminum frame with a 12 by 8 inch (0.3 by 0.2 m) opening to which a 3- to 5.5-ft (0.9 to 1.65 m) long trailing net is attached. Bedload traps are installed on ground plates that are anchored to the stream bottom with metal stakes. Traps do not have to be hand-held while sampling and have a large volumetric capacity. This permits collection of bedload over relatively long intervals, typically one hour per sample. In this document, we provide detailed guidelines for bedload trap construction and operation. We describe component parts and offer instructions for making the nets and assembling the sampler. Appropriate site selection and preparation are discussed as well as bedload trap installation, use, and maintenance. These guidelines also show how to process the collected bedload samples in the field and how to perform some of the typical calculations used in bedload evaluation.
