Download or read book Theoretical Morphodynamics: River Meandering written by Giovanni Seminara and published by Firenze University Press. 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.

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.

This book was released on 2024-03-15 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents the mechanistic foundations of the theory of Morhodynamics, a discipline that investigates the shape of the erodible boundary of natural water bodies. We focus on the fluvial Morphodynamics of straight erodible channels, providing the basis for subsequent extensions to meandering rivers (treated in the companion monograph 2 of this series) and braided rivers. We present basic notions on the Mechanics of Turbulent Flows and Sediment Transport in straight open channels with mobile beds. We then investigate their morphodynamic equilibrium and its instability, that leads to the formation of a variety of bedforms observed in natural rivers. In particular, fluvial bars will deserve special attention as the fundamental building block of large scale fluvial patterns.
Book Synopsis Analysis and Modelling of River Meandering by : Alessandra Crosato
Download or read book Analysis and Modelling of River Meandering written by Alessandra Crosato and published by IOS Press. This book was released on 2008 with total page 272 pages. 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.

Book Synopsis River Morphology by : Joachim Mangelsdorf
Download or read book River Morphology written by Joachim Mangelsdorf and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: River Morphology deals with the interaction between flowing waters in rivers and their environment. Based on the representation of basic flow parameters, the geometry, classification and historic development of rivers are treated. Any change in the environment, occurring naturally or caused by man, leads to very sensitive reactions in river flow and transport. Thus this synopsis of geoscientific studies and hydraulic engineering experience is presented to help develop the unterstanding of how to handle nature with care.
Book Synopsis Multi-scale Approach of River Morphodynamics by : Filippo Chiodi
Download or read book Multi-scale Approach of River Morphodynamics written by Filippo Chiodi and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis has been devoted to three different problems related to the morphodynamics of rivers. The first of them concerns sediment transport, for which a two-phase flow model has been proposed, valid in both viscous and turbulent regimes. As a main result, this model describes the transition from bed load to suspended load when the Shields number is increased. The second subject was the formation of bars. We revisited the linear stability analysis of these bedforms in order to emphasize the role played by the saturation length. We have shown that this saturation length controls the transition from ripples to bars. The third and most developed aspect of this PhD work was dedicated to the formation of meanders. By means of 3D RANS equations, we have performed a detailed description of hydrodynamics in a channel with both modulated bed and undulating banks. Coupled to sediment transport, the linear stability analysis of the problem gives predictions for the growth rate, the migration velocity and the shape of the bed for given meandering banks of wavenumber k. These predictions are in quantitative agreement with experimental data we obtained in a small flume: the entire dispersion relation is fitted with reasonable parameters of the modeling, but also the bed modulation is correctly reproduced. On the qualitative sicle, we have identified the mechanism responsible for this instability. This mechanism is different to thàt proposed by Einstein and it is also different to the resonance proposed by Blondeaux & Seminara. Finally, we have shown that depth-averaged (Saint-Venant) equations are not able to reproduce the instability.

Download or read book River Hydro- and Morphodynamics: Restoration, Modeling, and Uncertainty written by Ari Joseph Posner and published by . This book was released on 2011 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of fluvial geomorphology is one of the critical sciences in the 21st Century. The previous century witnessed a virtual disregard of the hydro and morphodynamic processes occurring in rivers when it came to design of transportation, flood control, and water resources infrastructure. This disregard, along with urbanization, industrialization, and other land uses has imperiled many waterways. New technologies including geospatially referenced data collection, laser-based measurement tools, and increasing computational powers by personal computers are significantly improving our ability to represent these complex and diverse systems. We can accomplish this through both the building of more sophisticated models and our ability to calibrate those models with more detailed data sets. The effort put forth in this dissertation is to first introduce the accomplishments and challenges in fluvial geomorphology and then to illustrate two specific efforts to add to the growing body of knowledge in this exciting field. First, we explore a dramatic phenomenon occurring in the Middle Rio Grande River. The San Marcial Reach of the Rio Grande River has experienced four events that completely filled the main channel with sediment over the past 20 years. This sediment plug has cost the nation millions of dollars in both costs to dredge and rebuild main channels and levees, along with detailed studies by engineering consultants. Previous efforts focused on empirical relations developed with historical data and very simple one dimensional representation of river hydrodynamics. This effort uses the state-of-the-art three-dimensional hydro and morphodynamic model Delft3D. We were able to use this model8to test those hypotheses put forth in previous empirical studies. We were also able to use this model to test theories associated with channel avulsion. Testing found that channel avulsions thresholds do exist and can be predicted based on channel bathymetric changes. The second effort included is a simple yet sophisticated model of river meander evolution. Prediction of river meandering planform evolution has proven to be one of the most difficult problems in all of geosciences. The limitations of using detailed three dimensional hydro and morphodynamic models is that the computational intensity precludes the modeling of large spatial or temporal scale phenomenon. Therefore, analytical solutions to the standard Navier-Stokes equations with simplifications made for hydrostatic pressure among others, along with sediment transport functions still have a place in our toolbox to understand and predict this phenomenon. One of the most widely used models of meander propagation is the Linear Bend Model that employs a bank erosion coefficient. Due to the various simplifications required to find analytical solutions to these sets of equations, efforts to build the stochasticity seen in nature into the models have proven useful and successful. This effort builds upon this commonly used meander propogation model by introducing stochasticity to the known variability in outer bank erodibility, resulting in a more realistic representation of model results.
