Methods for measuring the saturated hydraulic conductivity of tills

Abstract

The texture of tills excludes many of the traditional methods for measurement of the saturated hydraulic conductivity. In the unsaturated zone a variant of the inverse auger hole method using a constant head and a lined pit is recommended. In the saturated zone measurements in dug wells are considered as the most representative method. Correlative methods can only be used for very approximate predictions of the saturated hydraulic conductivity in till. -from Author
