Particle-laden density flows (e.g. pyroclastic flows, snow avalanches, rivers, turbidity currents) transport huge amounts of sediments across our planet and form some of the largest sediment accumulations on Earth. Interaction of density flows with erodible beds can create a wide range of bedforms and deposits whose morphology relates to the parent flow conditions (e.g. antidunes, chutes-and-pools, cyclic steps which are suggested to result from supercritical flows). However, we know little about the triad of flow dynamics, flow interaction with erodible beds and bedforms, and the resulting sedimentary products. How can we read resting sedimentary deposits and invert the parent dynamic flow conditions from them?
This session aims to bring together field researchers, experimentalists and numerical modellers with an expertise in sedimentology, fluid mechanics and related disciplines to further explore density and supercritical flow dynamics, bedform dynamics and the sedimentary structures they produce. The session welcomes studies across differing spatial and temporal scales, from large-scale organisation patterns down to the grain-scale, as well as the palaeo-dynamic and morphodynamic aspects of control and feedback between flow, sediment transport, bedform evolution and deposits.
