Detailed Summary of the Book

The book meticulously covers the essential topics of fluvial hydrodynamics and sediment transport, ranging from the fundamental principles of fluid mechanics to the intricate dynamics of sediment-laden flows. The major content is divided into logically sequenced chapters that build progressively on each other to provide a holistic understanding of the subject.

Initial chapters delve into the properties of natural flows, such as velocity profiles in open-channel flows, energy gradients, and turbulence properties. The book then transitions into sediment transport phenomena, addressing issues such as bedload and suspended transport, sediment re-suspension, and particle sorting. Advanced sections explore topics like erosion processes, channel morphology, river stability, and sediment transport modeling.

Characterized by both depth and breadth, the discussions include mathematical derivations, observational studies, and experimental data to reinforce theoretical concepts. Innovative methods in numerical modeling, laboratory flume studies, and in situ field observations receive special attention, tackling real-life applications such as river engineering, dam impacts, and sediment-related disasters. Each chapter contains numerous solved examples, thought-provoking exercises, and graphical illustrations to enhance comprehension.
