Perméabilité estimée par la granulometrie. Proposition d’une méthode et test de son efficacité

Abstract

We propose a new method of estimation of permeability based on Konezy formula. We show that this method is better than Hazen formula employed when d60/d10 > 2. The probability to obtain with our method a factor 10 over or under estimation of permeability is less than 10 %.
