Synopsis In this book an effort was made to examine the reach-scale braiding process and its impacts on bank erosion and channel morphodynamics, to assess sedimentary properties and downstream sorting of sediment size classes in connection with flow patterns, and to estimate morphological changes and sediment balance over decadal timescales using the status of recent methodological advancement and progress of studies in braided systems. In addition, impact of flooding on bar instability and human settlements, agricultural lands and natural vegetation are also considered.
