 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 |
