River Bedforms: Flow, Sediment and Morphological Dynamics

Daniel Parsons, Jim Best

Complex interactions between river flow and the transport of mobile sediment give rise to a suite of bedforms that are essential to interpretations and reconstructions of fluvial palaeoenvironments. This session aims to highlight and explore the latest developments in research concerning the many aspects of the complex interactions between flow, bedforms and alluvial sedimentary structures. The session seeks to integrate research from the description and interpretation of bedforms in the rock record, through to field quantification of modern rivers, and experimental and numerical models of alluvial bedforms and their morphodynamics. We encourage contributions across a suite of spatial and temporal scales, from channel scale to the grain-scale, and from turbulence scales through to extreme events and longer-term impacts on bedform dynamics. The session encourages contributions from field, laboratory, theoretical, and numerical approaches intended to advance our knowledge of how to decipher information contained in alluvial bedforms, with an aim to foster discussions and debate between researchers investigating bedform dynamics and their sedimentary signatures.
