ABSTRACT

This chapter presents a review of the available electrical mixing models, their applicability and limitations, descriptions of practically applicable models developed by G. Kibria and S. Hossain, and an evaluation of geotechnical parameters, using Kibria and Hossain's models. During evaluation of the geotechnical properties, cation exchange capacity (CEC) was empirically estimated, using the correlation proposed by Y. Yukselen and A. Kaya. It should be noted that the geotechnical properties are only valid for the compacted clay model assumptions and within the parameter ranges applicable for that model. According to P. Shah and D. Singh study, the clay fraction can be linearly correlated with the CEC of the soils. Shewartz et al. conducted a study to quantify field-scale moisture content using electrical resistivity imaging. Kibria and Hossain's undisturbed clay model was validated in the laboratory and in two sites, using borehole data and moisture sensor results.
