X–ray computer–tomography scan images obtained during these tests show a process which could be described as a kinematic density or porosity–wave motion. Forchheimer's flow law, holding in the post–critical regime, is calibrated by using the storage equation and the data concerning the propagation velocity of the observed porosity waves. Finally, the observed rarefaction waves are simulated mathematically and experimental results are back–analysed.
