The SUCHY project: seeing through the hyporheic interface.

Experiments shows that 3D Stokes flow through granular porous media have chaotic streamlines at pore scale.

Dense granular flows driven by gravity show non-trivial rheologies

Bedload transport in montaineous streams present spatio-temporally correlated fluctuations

Cyclic steps results from sub-critical bifurcation and show hysteretical behavior
