Bedform dynamics, deposits and sedimentary structures (co-organized)PICO session 
Convener: Thaiënne van Dijk  | Co-conveners: Sophie Hage , Jim Best , Maria Azpiroz-Zabala , Guilhem Amin Douillet 
Sedimentary bedforms, and their depositional products, 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 sedimentary structure thus represents a palaeo-surface expression, and therefore these bedforms contain a record of the geomorphology driven by the flow conditions, provided that one understands how to invert and read this history.

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

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

Contributions from field, laboratory, theoretical, and numerical approaches are invited in order to advance 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 and their sedimentary products.
