Bedform morphodynamics on Earth and in extra-terrestrial environments: current understanding of a complex interplay
Topographic sediment features arise from the complex interaction between flow and transport of sediment under the action of a current - unidirectional, oscillatory, combined or multidirectional. Depositional bedforms occur in a wide variety of environments, including deserts, rivers, estuaries, deltas, beaches, continental shelves, deep seas, volcanic regions, and sub- and pro-glacial environments. They are generated and affected by a wide range of flows and forcings, such as aeolian transport, waves, tidal currents, offshore storms, temperate glacier flows, turbidity currents and subaqueous mass flows, deep-sea currents, pyroclastic currents on Earth and other flows on extra-terrestrial bodies. Bedforms leave a unique signature in sedimentary records, allowing stratigraphic interpretation and reconstruction of contemporary and past climate and landscape evolution in terrestrial and other planetary environments.
This session aims to highlight many aspects of the complex interaction between flow, bedforms and sedimentary structures on Earth as well as on extra-terrestrial surfaces, from their description to interpretation, and from modelling to experiments and field quantification, with studies ranging 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 and bedform evolution.
The session welcomes contributions from field, laboratory, theoretical, and numerical approaches intended to advance our knowledge of how to decipher information contained in terrestrial and extra-terrestrial sedimentary bedforms, and help foster fruitful discussions between sedimentologists, geomorphologists, hydrologists, physicists and all researchers working on understanding bedform dynamics and their sedimentary signatures.
