Sedimentary bedforms are the result of a complex interplay between the erosion, transport and deposition of grains under the action of a current - unidirectional, oscillatory, combined or multidirectional. Each lamina preserved within a depositional sedimentary structure thus represents a palaeo-surface expression, and therefore these bedforms contain the record of the geomorphology driven by the palaeo-flow conditions, provided that one understands how to invert and read this history.

Sedimentary structures are also generated in a wide variety of environments, including:
-rivers
-pyroclastic currents
-aeolian wind-driven transport
-glacial- , sub- and pro- glacial environments
-estuarine, lacustrine and deltaic settings
-shoreline and continental shelf
-offshore storms (tempestites)
-turbidity currents and subaqueous mass flows
-deep sea currents

This session invites contributions regarding all aspects of depositional sedimentary structures, from their description to interpretation, and from modelling to experiments to field quantification. The session will also concern 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 and bedform evolution.

Contributions from field, laboratory, theoretical, and numerical approaches are welcome in order to progress our knowledge of how to decipher the information contained in sedimentary bedforms, and help foster fruitful discussions between sedimentologists, geomorphologists, hydrologists, physicists and all researchers working on understanding bedform dynamics. Significant attention will be given to questions on supercritical flows.
