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.

How to access SSP3.5
Session SSP3.5 runs as a vPICO session. Everybody, conveners/chair/speakers as well as attendees, join the live session page on EGU21. While attendees stay on this live session page and see the live presentations via stream, you as convener/chair/speaker are required to enter the BigBlueButton (BBB) live video chat to give your presentation.
Please keep the live session page open on this browser tab and join the BBB video chat in parallel on another browser tab through the button below. Your personal breakout text chat following the live presentations are linked from the live session page tab, not from the additional BBB video chat tab.Enter BBB video chat
