 Subject group   Keyword   Abstract (in english)    The hydraulic conductivity of sands depends aminly on their granulometric composition, which heterogeneity is expressed with the ratio U=d 60/d10, where d60, (d10) is the grain size belonging to 60% (10%) of the undersizes. The representative size of grains is being defined in different ways, often, it is the value d10, sometimes it is dw, which in substance is the size of grains, which hydraulic resistance would be equal to resistance of the equal number of different size grains of given soil. In this study, a proposition is given to describe the granulometrics of sands with the characteristics of Gauss logarithmic  normal distribution LN ( , 2), and so, with the factors , , which would also be the basis for determining of the coefficient of hydraulic conductivity
