Projet ANR SegSed : Ségrégation en transport de Sédiments.

SegSed is a multi-scale and multi-disciplinary study of size segregation to ultimately improve sediment transport modelling.

An important reason for our limited ability to predict sediment transport is due to the very wide range of grain sizes leading to size segregation or grain size sorting. Segregation in bedload, a major experimental and modelling scientific bottleneck largely modifies fluxes and results in patterns seen ubiquitously in nature.
The specific objectives of the project are to (i) experimentally improve our understanding of size segregation physical processes, especially particle-particle interactions and the feedback with the transporting fluid (ii) develop a hierarchy of process-based models at different scales for
understanding, predicting and upscaling .
