Özet

Soil is a heterogeneous medium which consist of liquid, solid, and gaseous phases. The solid and

liquid phases play an essential role in soil spontaneous electrical phenomena and in behavior of

electrical fields, artificially created in soil. Soil air can be considered as a dielectric. Soil electrical

properties are the parameters of natural and artificially created electrical fields in soils and influenced

by distribution of mobile electrical charges, mostly inorganic ions, in soils. Geophysical methods of

vertical electrical sounding were used for measuring soil electrical properties and tested in different

soil studies. For our aim, study area is selected in Istanbul (Yesilkoy, Florya, Basinkoy) and Golcuk. In

this area, the electrical resistivity is measured by VES (Vertical Electrical Sounding) and in many points

of this location by McPHAR resistivity equipment. For geotechnical purposes, on the soil samples from

borings, it was applied soil mechanics laboratory procedures and the soil water contents are

determined from these samples. Relationships between soil water content and electrical parameters

were obtained by curvilinear models. The ranges of our samples are changed between 1 - 50 ohm .m

(for resistivity) and 20 - 60 %( for water content). For this range, the relation between resistivity (R) and

water content (W) of soils is found to be given as W = 49, 21e-0,017R.
