ABSTRACT: A Guelph permeameter test is modelled using SEEP/W software using the full unsaturated property functions of six soils. The results of the tests are analysed using Glover's equations, the Guelph Richards single head analysis and the Guelph Richard's simultaneous equations analysis. The results are compared to the known values of the hydraulic conductivity of each soil. The accuracy of the Glover analysis was between -46% to 240%, the accuracy of the Guelph permeameter single head analysis was between -82% to 39% and the Guelph permeameter simultaneous equations approach yielded negative values of Kfs.

RÉSUMÉ: Un essai de perméabilité de Guelph a été modélisé à l'aide du logiciel SEEP/W en utilisant les courbes complètes de propriétés non saturées de six sols. Les résultats de la modélisation ont été analysés à l'aide de la méthode de Glover, de la méthode à charge unique de Guelph-Richards et de la méthode de résolution simultanée des équations de Guelph-Richards. La méthode de Glover a donné des valeurs entre -46% et 240% de la réelle valeur de la conductivité hydraulique saturée, la méthode à charge unique de Guelph-Richards a donnée des valeurs entre -82% et 39% de la valeur réelle alors que la méthode par résolution d'équations simultanée de Guelph-Richards à donné des valeurs négatives de Kfs.
