Bedform dynamics: toward quantitative interpretations (co-organized)PICO Session
Convener: Guilhem Amin Douillet 
PICO
 / Mon, 18 Apr, 15:30–17:00  / PICO spot 3
Sediment bedforms are the result of a complex interplay between erosion, transport and deposition of clasts under the action of a current. Each lamina forming a sedimentary structure represents a palaeo-surface expression. Sediment bedforms thus contain the record of palaeo-flow conditions, provided that one understands how to read this history.
The session will encompass all aspects around flow-driven sedimentary structures, from their description to the interpretation, going through modeling and experiments. From large-scale organisation patterns down to the grain-scale, the palaeo-dynamics and morphodynamics aspects of control and retro-control between the flow, the particle load and the bed will be investigated.
Contributions from field, laboratory, theoretical, and numerical approaches are welcome to decipher the information contained in sediment bedforms, and trigger fruitful discussion between sedimentologists, hydrologists, physicists and all researchers working on bedform understanding.
