Supercritical flows include catastrophic free-surface flows, subaqueous density currents, pyroclastic density currents, and katabatic winds. These flows create bedforms such as antidunes, chutes-and-pools, cyclic steps and rhomboidal patterns, which lead to the formation of upper flow-regime sedimentary structures that are often ascribed a low preservation potential in the stratigraphic record as a result of their high-energy formative conditions. However, the scarcity of observations may in part be due to a lack of diagnostic criteria for their recognition. Flume experiments have been pivotal to our understanding of the morphodynamics of upper flow-regime bedforms, showing a close association with stationary waves and hydraulic jumps. Our knowledge is enlarged with studies reporting on direct measurements of supercritical flows, in particular in (glacio-)fluvial settings and, more recently, modern turbidity currents. Numerical simulations also have significantly contributed to this exciting field of research. This session aims to bring together experimentalists, numerical modellers and field geologists with an expertise in sedimentology, fluid mechanics and related disciplines to further explore the genesis of supercritical-flow bedforms and related sedimentary structures. Students and young researchers are encouraged to submit. ----------------------------------------------------------------------------------------------- ================================================================ # 不達メールアドレスは随時配信リストより削除します. # メルマガのバックナンバーは堆積学会ホームページからご覧いただけます. ■■■■■■■■■■■■■■■■■■■■■■■■■■■ 日本堆積学会 事務局 〒305-8567 茨城県つくば市東1-1-1中央第七 産業技術総合研究所地質調査総合センター(田村 亨)内 メールアドレス: ホームページURL: http://sediment.jp/ ■■■■■■■■■■■■■■■■■■■■■■■■■■■■■
