The purpose of the study was to evaluate the usefulness of EIS (Electrical Impedance Spectroscopy) to observe the process of water filtration through the earth embankment body. The tests were carried out in a hydraulic channel on a model of the embankment made of silty coarse sand. The filtration flow was caused by multi-stage lifting and lowering the water level in the hydraulic channel. Measurements of soil resistivity values were referred to automatically registered piezometric water level. The obtained results showed significant convergence of changes in soil resistance due to the water flow with changes in the level of filtration water measured in the piezometer. ER -
