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.

This book was released on 2024-04-05 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph discusses the mechanics of Meandering Rivers with the help of the mathematical and modeling tools built up in the previous monograph of the same Authors (monograph 1 of the present series). After introducing the reader to the ubiquitous character of meandering streams, we discuss the hydrodynamics of curved channels with fixed beds and banks. Next, we extend the analysis to account for the mobile character of the bed and show that it gives rise to the alternate sequence of riffles and pools that characterize river meanders. Allowing for the erodible character of the river banks then allows to build up a rational theory of meander formation able to explain most of the features observed in nature: meander growth, migration, skewing, multiple loops, cutoffs and meander belts.

Download or read book River Dynamics written by Bruce L. Rhoads and published by Cambridge University Press. This book was released on 2020-04-29 with total page 544 pages. 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.

Download or read book River Mechanics written by Pierre Y. Julien and published by Cambridge University Press. This book was released on 2002-08-19 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook offers a thorough analysis of rivers from upland areas to oceans. It scrutinizes select methods underlining both theory and engineering applications, emphasizing the mechanics of flood wave propagation and sediment transport in rivers. The text covers fundamental principles, engineering analysis, and engineering design, with problems, examples, and case studies throughout. Channel stability and river dynamics are examined in terms of river morphology, lateral migration, aggradation, and degradation. Detailed treatments of riverbank stabilization and engineering methods are provided, while separate chapters cover physical and mathematical models. This essential text presents both the theory and design of measures to reduce flood impact and bank erosion, to improve navigation, and to increase water supply to cities and irrigation canals. Over 100 exercises and nearly twenty case studies make this book an invaluable learning tool for students, and researchers and practitioners will find it a concise resource on the mechanics of rivers.

Download or read book Prediction of Meander Migration for Four Rivers in Texas at Roadway Crossings written by Fahmidah Ummul Ashraf and published by . This book was released on 2013 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: River meandering can endanger the hydraulic structures by lateral expansion and down-valley translation of meander bends. In this study, the RVR Meander model was used to predict the meander migration for four bridge crossings in the state of Texas, USA. The bridge crossings are SH 105 at the Brazos River, FM 787 at the Trinity River, US 90 at the Nueces River and SH 63 at the Sabine River. A widely used migration coefficient approach developed by Ikeda et al. (1981) was adopted, which relates migration rate linearly to vertically-averaged near bank excess velocity through the use of a coefficient of bank erosion. This study estimates erosion coefficient values for eroded banks from measured long term migration rates and computed near bank excess velocities. The values of erosion coefficients are calibrated using the RVR Meander model with the least prediction error. The predicted planform evolution using the model suggests that the migration coefficient approach used in the model can capture the growth of meander bends if they do not change the migration direction. In general, the model can predict migration well in lateral and downstream direction. This study also attempts to examine the extent to which erosion coefficient depends on resistance of bank material to fluvial erosion. Erosion Function Apparatus (EFA) erodibility values represent the resistance of bank material to fluvial erosion. At the upstream bends adjacent to the road crossings for which both erosion coefficients and EFA erodibility values were obtained, it was found that erodibility values follow the trend of erosion coefficients, unless significant hydraulic or geomorphic changes occurred in the watershed and in the channel due to the human activities. It opens up the possibility that erosion coefficients may be estimated directly from the bank material properties instead of using the historical maps. This suggests that for long term (several decades) meander migration riparian vegetation is not a major controlling factor. This hypothesis requires further testing with data sets from other road crossings over rivers.

This book was released on 2008-03-11 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Klamath River basin, which spans parts of southern Oregon and northern California, has been the focus of a prominent conflict over competing uses for water. Management actions to protect threatened and endangered fish species in the basin have left less water available for irrigation in dry years and heightened tensions among farmers and other stakeholders including commercial fishermen, Native Americans, conservationists, hunters, anglers, and hydropower producers. This National Research Council book assesses two recent studies that evaluate various aspects of flows in the Klamath basin: (1) the Instream Flow Phase II study (IFS), conducted by Utah State University, and (2) the Natural Flow of the Upper Klamath Basin study (NFS), conducted by the U.S. Bureau of Reclamation (USBR). The book concludes that both studies offer important new information but do not provide enough information for detailed management of flows in the Klamath River, and it offers many suggestions for improving the studies. The report recommends that a comprehensive analysis of the many individual studies of the Klamath river basin be conducted so that a big picture perspective of the entire basin and research and management needs can emerge.
