Abstract

In this study, the electrical resistivity of soil having different chemical weathering index (CWI) was measured, and the correlation between CWI and the electrical resistivity was estimated. The electrical resistivity of soil varies with CWI of soil. The difference in the electrical resistivities of soils having different weathering degrees is clear at lower water contents. At the volumetric water contents estimated in this study, CWI could be described by a linear equation of electrical resistivity with the constants related to the volumetric water content. The findings in this study suggest that the electrical resistivity could be used as an effective alternative for estimating the weathering degree of soil.
