Apparatus for Measuring Hydraulic Conductivity of Undisturbed Soil Samples


Since undisturbed soil samples can be obtained to a depth of about 50 m, a laboratory apparatus for the determination of the hydraulic conductivity has been developed. The tests with this apparatus provide data on vertical hydraulic conductivity; horizontal conductivity; the presence of semipervious or pervious confining layers; and the correlation between hydraulic conductivity and granular composition, porosity, minor structures, etc. The data are used for comparison with data obtained from other methods and as a basis for computation of directionand intensity of flow under natural conditions. The permeameter consists of a container in which simultaneous tests of 50 samples are possible, with both the constant-head and the falling-head methods. The hydraulic head applied for the flow ranges from 2 to 20 mm, depending on structure and texture of the samples.
