Interpretive Summary: Coherent Flow Structures in Open Channels presents the first integrated treatment, across a wide range of spatial and temporal scales, of the origins and characteristics of coherent (organized) fluid motions and their influence on sediment transport and stream bed morphology. Coherent flow structures are examined systematically across a range of scales from completely flat beds, stream beds with grain and bedform through to the largest scales, where structures may be associated with stream channels. A total of thirty-three (33) chapters are presented from an international and interdisciplinary authorship comprising geologists, geographers, engineers, and mathematicians, each of whom is examining the nature of turbulent coherent flow structures using theoretical, experimental and field-based approaches.

Technical Abstract: Coherent Flow Structures in Open Channels presents the first integrated treatment, across a wide range of spatial and temporal scales, of the origins and characteristics of coherent fluid motions and their influence on sediment transport and bed morphology. Coherent flow structures are examined systematically across a range of scales from flat-bed boundary layers and the origins of turbulence, grain and bedform roughness generated structures over individual grains, gravel- beds, and bed waves through to the largest scales, where structures may be associated with bars, meander bends and channel confluences. A total of thirty-three (33) chapters are presented from an international and interdisciplinary authorship comprising geologists, geographers, engineers, and mathematicians, each of whom is examining the nature of turbulent coherent flow structures using theoretical, experimental and field-based approaches.
