APPLICATION OF THE ELECTRICAL IMPEDANCE SPECTROMETRY METHOD FOR MONITORING FILTRATION PHENOMENA ON THE EXAMPLE OF KAROLINKA EARTH DAM

The paper presents the results of monitoring electrical properties of the soil of the body of the earth-fill dam of the Karolinka water reservoir in the fourth year after its reconstruction ended. Monitoring was carried out using the Z-meter device applying the electric impedance spectrometry method with the focus on seepage through the earth-fill dam of the water reservoir. Information about the changes that occurred in the dam body before and after the implementation of the measure (the construction of a cut-off wall when the dam was reconstructed in 2013) was obtained by monitoring the changes of the electrical resistances of the soil of the dam with time.
