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\u00a0Hz\u201310\u00a0kHz. The engineering and hydraulic properties of these soils, that is, the hydraulic conductivity K, void ratio e, fines content fc, intergranular void ratio eg and the dry density \u03b3d 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 \u03b7 and resistivity \u03c10 and that of \u03b7 and grain percent resistivity \u03b4r clusters soils with high and low values of hydraulic conductivity, whereas crossplots of relaxation time \u03c4 and \u03c10 clusters soils with high and low intergranular void ratio. Regression models are developed using the parameters \u03b7 and \u03b4r to predict the hydraulic conductivity with R2=0.85; \u03c10 and \u03c4 to predict the intergranular void ratio with R2=0.74 and \u03c10 and \u03b7 to predict the dry density with R2=0.67.<\/jats:p>","DOI":"10.1190\/geo2010-0299.1","type":"journal-article","created":{"date-parts":[[2011,11,21]],"date-time":"2011-11-21T18:33:51Z","timestamp":1321900431000},"page":"F329-F338","source":"Crossref","is-referenced-by-count":9,"title":["Predicting the engineering and transport properties of soils using fractal equivalent circuit model: Laboratory experiments"],"prefix":"10.1190","volume":"76","author":[{"given":"Fred Kofi","family":"Boadu","sequence":"first","affiliation":[{"name":"Duke University 1 , Department of Civil and Environmental Engineering, Durham, NC, .
