Pore fluid pressure diffusion in defluidizing granular columns

Pore fluid pressure variations play an important role in the motion of natural granular flows like debris and pyroclastic flows. Pore pressure in a defluidizing air‐particle bed was investigated by means of experiments and numerical modeling. Experiments consisted of recording the defluidization pro...
