The geometry of a meander is that of a random walk whose most frequent form minimizes the sum of the squares of the changes in direction in each unit length. Changes in direction closely approximate a sine function of channel distance. Depth, velocity, and slope are adjusted so as to decrease the variance of shear and the friction factor in a meander over that in an otherwise comparable straight reach of the same river.

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.

Originally published in 1982, this book presents a detailed review of alluvial river form and process and integrates the distinct but related approaches of geomorphologists, geologists and engineers to the subject. It outlines the environmental catchment factors that control the development of channel equilibrium and provides a detailed account of the sediment transport processes that represent the physical mechanisms by which channel adjustment occurs. Where possible it evaluates theoretical analyses in the context of the empirical evidence. Rivers should prove a valuable textbook for geomorphology students on advanced undergraduate courses on river behaviour and will also be of interest to students of hydraulics and sedimentology and to those concerned with civil and environmental engineering, river management and channel design, maintenance and management in the water industry

Resilience and Riverine Landscapes presents contributed chapters from global experts in Riverine Landscapes, making it the most comprehensive reference available on the topic. The book explores why rivers are ideal landscapes to study resilience and why studying rivers from a resilience perspective is important for our biophysical understanding of these landscapes and for society. The book focuses on the biophysical character of resilience in riverine landscapes, providing an interdisciplinary perspective of the structure, function, and interactions of riverine landscapes and the ecosystems they contain. The editors conclude by proposing a research agenda for the future, emphasizing the need for transdisciplinary research across a range of spatial and temporal scales and research domains. - Presents the resilience of rivers with both a theoretical and applied focus - Includes case studies from a wide geographical base, allowing for a full range of viewpoints - Showcases how resilience is being incorporated into the study and management of riverine landscapes - Includes a transdisciplinary focus on riverine landscapes, from theory to applied, and from biophysical to social-ecological systems

The plate tectonics revolution in the earth sciences has provided a valuable new framework for understanding long-term landform development. This innovative text provides a comprehensive introduction to the subject of global geomorphology, with the emphasis placed on large-scale processes and phenomena. Integrating global tectonics into the study of landforms and incorporating planetary geomorphology as a major component the author discusses the impact of climatic change and the role of catastrophic events on landform genesis and includes a comprehensive study of surface geomorphic processes.

This book presents approaches to landscape modelling not only from geography but also from various related disciplines, especially from applied mathematics, computer science, and geophysics. New methods of terrain representation, analysis and classification are presented as well as short- and long-term process models. The intention of the book is not to give a complete overview of these broad and complex topics, but to stimulate interdisciplinary cooperation and to encourage scientists to consider the ideas of related disciplines.

This book explains the causes, mechanisms and dimension of sedimentation in the Rupnarayan River, which offers a representative example of a tidal river combining fluvial and marine processes. The book is unique in addressing all the hydrodynamic characteristics of the river, especially the tidal impact, sediment load and textural characteristics of the sediments. ; The data presented here was gathered through continuous field monitoring using state-of-the-art techniques and robust laboratory analysis, and will help readers develop a systematic understanding of sedimentation processes. As such, the book offers a valuable resource for all students and researchers conducting research on fluvial geomorphology and sedimentology. In addition, the outcomes it presents will benefit engineers, hydrologists, planners and other authorities affected by a number of aspects related to sedimentation.

Rivers form one of the lifelines in our society by providing essential services such as availability of fresh water, navigation, energy, ecosystem services, and flood conveyance. Because of this essential role, mankind has interfered continuously in order to benefit most and at the same time avoid adverse consequences such as flood risk and droughts. This has resulted in often highly engineered rivers with a narrow set of functions. In the last decades rivers are increasingly considered in a more holistic manner as a system with a multitude of interdependent processes. River research and engineering has therefore added to the river fundamentals also themes like ecohydraulics, consequences of climate change, and urbanisation. River Flow 2020 contains the contributions presented at the 10th conference on Fluvial Hydraulics, River Flow 2020, organised under the auspices of the Committee on Fluvial Hydraulics of the International Association for Hydro-Environment Engineering and Research (IAHR). What should have been a lively physical gathering of researchers, students and practitioners, was converted into an online event as the COVID-19 pandemic hindered international travelling and large gatherings of people. Nevertheless, the fluvial hydraulics community showed their interest and to be very much alive with a high number of participations for such event. Since its first edition in 2002, in Louvain-la-Neuve, this series of conferences has found a large and loyal audience in the river research and engineering community while being also attractive to the new researchers and young professionals. This is highlighted by the large number of contributions applying for the Coleman award for young researchers, and also by the number of applications and attendants to the Master Classes which are aimed at young researchers and students. River Flow 2020 aims to provide an updated overview of the ongoing research in this wide range of topics, and contains five major themes which are focus of research in the fluvial environment: river fundamentals, the digital river, the healthy river, extreme events and rivers under pressure. Other highlights of River Flow 2020 include the substantial number of interdisciplinary subthemes and sessions of special interest. The contributions will therefore be of interest to academics in hydraulics, hydrology and environmental engineering as well as practitioners that would like to be updated about the newest findings and hot themes in river research and engineering.
