AbstractDielectric methods are widely used to monitor in situ volumetric water content in granular or fine-grained soils with low to medium plasticity. However, the use of these methods in highly plastic, unsaturated, expansive clay soil is very limited. For highly plastic clay, manufacturer-provided calibration curves are generally not applicable and soil-specific calibrations are required. This paper presents the results of a calibration program carried out for various commercially available probes using compacted specimens of highly plastic Regina Clay in the laboratory. The influence of dry density and temperature on dielectric permittivity for the soil was also studied. The applicability of the dielectric methods to monitor water content in Regina Clay is also discussed.
