This note presents some constant-head permeability test results on 30 granular mixtures. These data are then interpreted using the grading entropy approach, as well as the ‘Hazen’, ‘Shepherd’, ‘Kozeny-Carman’, and ‘Chapuis’ models. The predictive power of each of the five methods is compared. A correlation between the normalised grading entropy coordinates and the coefficient of permeability is presented. Permeability zones on the normalised entropy diagram are identified.
