Available in PDF, EPUB and Kindle. Book excerpt: This thesis examines the morphological changes of non-tidal meandering rivers at the spatial scale of several meanders. With this purpose, a physics-based mathematical model, MIANDRAS, has been developed for the simulation of the medium-term to long-term evolution of meandering rivers. Application to several real rivers shows that MIANDRAS can properly simulate both equilibrium river bed topography and planimetric changes. Three models of different complexity can be obtained by applying different degrees of simplification to the equations. These models, along with experimental tests and field data, constitute the tools for several analyses. At conditions of initiation of meandering, it is found that river bends can migrate upstream and downstream. This depends on meander wave length and width-to-depth ratio, irrespective of whether the parameters are in the subresonant or the superresonant range.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Understanding the mechanism and behaviour of rivers flowing in alluvium is a most challenging subject. The conditions presented by a natural river are far from simple: the flow varies with location and time, and the granular structure and cohesive properties of the alluvium are rarely homogeneous. River Mechanics addresses this subject and aims to improve the understanding and formulation of the fluvial processes which occur in rivers. Topics covered include the interpretation of turbulence in the light of recent advances in the field, and current thinking on the regime concept.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Fluvial System written by Stanley Alfred Schumm and published by . This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1977, this is a classic of the geomorphology literature. Erosion, transport, and deposition of sediment within river catchments concern a wide range of earth scientists and profoundly affect land management. Upland soil removal engages the attention of soil conservationists, hydraulic engineers deal with fluvial sediment transport and river channel morphology, and patterns of sediment deposition in riverine and coastal lowlands affect navigability, the habitability of valley floors and the distribution of groundwater and minerals. The author argues persuasively that fluvial geomorphology, sedimentology and stratigraphy provide insights into each of these components of the river basin. "This volume, with its generous illustrations will be welcomed by earth scientists generally. It fills an important niche in the fluvial literature and its lucid style and clear exposition place it well within the range of students in any form of higher education." Nature "As a synthesis of the fluvial system and its effects on the landscape, as a primer in fluvial geomorphology and sedimentation for the planner, engineer and economic geologist, and as a stimulator of geomorphic thought, this book is most valuable." American Scientist Dr. Schumm is an internationally recognized geomorphologist who has published 150 papers and authored and edited 11 books. His primary experience has been in the investigation and analysis of fluvial systems. He has applied the concepts of geomorphology, fluvial hydraulics and geology to analyze alluvial river form and shape, sediment transport and effects of man-induced changes on river systems throughout the United States and in numerous foreign countries. He has also been involved in the interpretation of lunar and Martian landforms. Dr. Schumm is a past Chairman of the Geopmorphology Division of the Geological Society of America, has served on technical and committees of the National Research Council, the Geological Society of America, the American Geophysical Union, International Geographic Union, the National Science Foundation and NASA. He has performed research, lectured and advised government agencies around the world.

Download or read book Quantifying the Connections Between Flow, Bar Deposition, and Meander Migration in Large Gravel-bed Rivers written by Candice R. Constantine and published by . This book was released on 2006 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predicting channel migration is a key component of designing plans for river management and restoration. Fundamentally, the lateral migration rate depends on the rate of excavation of the outer bank toe. This rate is a function of bank resistance to erosion, flow velocity, bend geometry, and sediment transport and storage. Although it is certain that all these variables play some role in determining migration rates in gravel-bed rivers, the importance of sediment storage in particular has not been thoroughly investigated. Currently employed meander migration models are driven by curvature effects on near-bank flow and account for differences in bank erodibility through use of a calibrated bank erosion coefficient. Despite increasing application of such models to sensitive management problems, it remains unclear how the coefficient varies with properties of the channel and to what extent it incorporates the effects of changes in bed-material storage on migration rate.

Available in PDF, EPUB and Kindle. Book excerpt: The main focus of this Special Issue of Water is the state-of-the-art and recent research on turbulence and flow–sediment interactions in open-channel flows. Our knowledge of river hydraulics is deepening, thanks to both laboratory/field experiments related to the characteristics of turbulence and their link to erosion, transport, deposition, and local scouring phenomena. Collaboration among engineers, physicists, and other experts is increasing and furnishing new inter-/multidisciplinary perspectives to the research of river hydraulics and fluid mechanics. At the same time, the development of both sophisticated laboratory instrumentation and computing skills is giving rise to excellent experimental–numerical comparative studies. Thus, this Special Issue, with ten papers by researchers from many institutions around the world, aims at offering a modern panoramic view on all the above aspects to the vast audience of river researchers.
