A modified kinetic theory for frictional-collisional bedload transport valid from dense to dilute regime
Rémi Chassagne, Julien Chauchat, Cyrille Bonamy
Modelling sediment transport is still a challenging problem and is of major importance for the study of particulate geophysical flows. In this work, the modelling of sediment trans…

Mobility of bidisperse mixtures during bedload transport
Rémi Chassagne, Raphaël Maurin, Julien Chauchat +1
The flow of segregated bidisperse assemblies of particles is of major importance for geophysical flows and bedload transport in particular. In the present paper, the mobility of bi…

Grain size segregation during bedload transport on steep slopes
Rémi Chassagne, Raphaël Maurin, Julien Chauchat +2
Size segregation in bedload transport is studied numerically with a coupled fluid-discrete element model. Starting from an initial deposit of small spherical particles on top of a…
