Frequency-dependent electrical measurements of soils contain useful information about their texture and structure that can be linked to their engineering and transport properties. We performed frequency-dependent electrical measurements on 29 natural soils with wide variability in physical and textural properties in a laboratory environment at a constant stress level and in the frequency range of 0.01 Hz–10 kHz. The engineering and hydraulic properties of these soils, that is, the hydraulic conductivity , void ratio , fines content , intergranular void ratio and the dry density are concurrently measured. The electrical behaviors of the soils are modeled with an equivalent circuit model, which are described by six circuit parameters. Relationships between the circuit parameters and the soil properties (geotechnical engineering and hydraulic) are investigated. Crossplots of frequency exponent and resistivity and that of and grain percent resistivity clusters soils with high and low values of hydraulic conductivity, whereas crossplots of relaxation time and clusters soils with high and low intergranular void ratio. Regression models are developed using the parameters and to predict the hydraulic conductivity with ; and to predict the intergranular void ratio with and and to predict the dry density with .
