スコープ | 和文 | In the last decade, flow processes, particularly supercritical flows and their deposits have become an important topic in order to improve our understanding of the formation and evolution of sedimentary fans including alluvial and fluvial systems but also glacigenic subaqueous and submarine fans. Researchers using numerical modelling, flume-tank experiments, and outcrop observations, described and analysed a wide range of bedforms that develop under supercritical conditions such as cyclic steps, unstable and stable antidunes and upper-plane beds. Nevertheless, some questions remain regarding the formation and evolution of these bedforms in different settings from rivers to submarine fans. This session aims to bring together experimentalists, numerical modellers and field researchers with an expertise in sedimentology, fluid mechanics both in open-channel and density flows, and related disciplines to further explore supercritical-flow and their deposits as well as the impact of flow criticality on the architecture of river, delta, subaqueous glacigenic fans and submarine fans. The session welcomes studies across different scales, from the grain-scale and the impact of grain-size of the formation of supercritical bedforms and associated sedimentary structures to large-scale flow processes controlling the architecture of rivers, deltas, subaqueous glacigenic and submarine fans. | |
