The saturated hydraulic conductivity of soil is one of the most importanthydrophysical characteristics. The ability of saturated hydraulic conductivity is leadthe water in soil, that is saturated with water. The content of this task was comparevalues of the saturated hydraulic conductivity of soil measured in laboratory on thedevice with variable hydraulic slope, against values measured by Špaček, where thevalues entered into the calculation by reading from the grading curves, which weregained by hydrometer method. Laboratory and calculated method of the saturatedhydraulic conductivity were subsequently evaluated by correlation. The result ofcorrelation was correlation coefficient, which showed that dependence betweenvalues of saturated hydraulic conductivity obtained by those above methods is nottoo significant.
