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.
