摘要：

A series of steady, spherically symmetric flows are used to determine the dependence of the hydraulic conductivity upon the pressure head. A feature of the method is that for each flow the pressure head needs to be measured at only one point. The effect of gravity can be evaluated on the basis of an analytical solution for a soil with an exponential dependence of the hydraulic conductivity upon the pressure head.
