The flow of water inside the soil can cause geothechnical problems, landslides for example. Hydraulic conductivity is the value that describes the ease with which a water can move through pore spaces of soil. The method used to find the value of hydraulic conductivity is usually impractical and expensive. Therefore, a more fruitful geophysical exploration method is required to become an alternative method, one of which is geoelectric method. Resistivity values obtained from 2D geoelectric method with Wenner-Schlumberger configuration will be used to estimate the hydraulic conductivity values of the underground soils. Ten samples of surface soil will be taken on two measurement fields in Cillin area. These soil samples’ hydraulic conductivity values were calculated using a simple test instrument made by the author with a permeability test including Falling Head method and Constant Head method. Linear equation relationship betweeen the hydraulic conductivity value and the resistivity value of the surface soil sample was used to calculate the values of hydraulic <br /> <br /> conductivity of the underground soils. The results showed that the values of the sandy soil hydraulic conductivity is in the order of 10-4 m / s and clay is in the order 10-7 – <br /> <br /> 10-8 m / s. There are irregularities in the estimation of hydraulic conductivity values for soil types that differ from surface soil samples. This is caused by the estimation <br /> <br /> equation that can only be used for the same soil type with the taken surface soil samples.
