About the Edition

Examines the morphological changes of non-tidal meandering rivers at the spatial scale of several meanders. A physics-based mathematical model, MIANDRAS, was developed for simulation of medium-term and long-term evolution of meandering rivers.

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 .

Consisting of 12 chapters, this publication contains information on sediment types and transport modes, channel morphology, methods of facies analysis, bars, facies models for alluvial fans and braided rivers, facies models for meandering rivers, facies models for anastomosed rivers, recognition of large rivers, large scale fluvial cycles, basin architecture and tectonic settings, and fuels and minerals . Also neglected by previous modelling efforts is bank–flow interaction and its role in meander evolution. We introduce a simple river meandering model based on topographic steering that has more in common with cellular approaches to channel braiding and landscape evolution modelling than to rigorous, physics‐based analyses of river meandering. First, flow and riverbed variation in a meandering channel are formulated in one dimension, after which the model is verified by comparing the numerical computation results with the existing flume experimental data. Next, the model for describing channel meandering shape deformation is . The analyzed data have been obtained by using a suitable physics‐based simulation model for river meandering able to reproduce reasonably the features of real rivers.

  Meandering-anabranching reaches are common in the lower Yangtze River. We used multi-source data to examine meandering-anabranching channel evolution. Main channel shifted in response to flow-sediment partition in each branch. Anabranching channels adjusted to reach sediment transport balance.   Abstract. Flood flow studies contribute to a huge percentage of research in the field of water resource. Considering a few simplifications, an attempt has been made to create an accurate one-dimensional, unsteady, flow model for the Barak River defining upstream section at Fulertaal ghat and downstream section at Badarpur ghat of the Barak River. Abstract A computer model for the dynamics of meandering rivers has been used to study the interplay between the migrating river and the changing sedimentary environment created by the meandering river itself. The model is based on the theory of Ikeda et al. and is closely related to that proposed by Howard. Bangshuai Han, Theodore A.
