Description(s):Abstract: Accurate knowledge about the spatial distribution of hydraulic properties in the subsoil are of great importance for any kind of hydrological modeling. Geophysical methods are able to provide high resolution images of physical properties in the soil which can be related to hydraulic properties. One of these techniques, electrical impedance tomography (EIT) images the complex electrical resistivity distribution in the ground. It has recently been shown, that spectral electrical properties can be related to hydraulic properties of saturated and partially saturated soils and rocks. As EIT can be performed also in a spectral manner (i.e. for a number of specified frequencies) spectral electrical parameters can be imaged by using this method which then allows for imaging hydraulic properties. In this study spectral electrical imaging was performed on successively drained artificial soil columns (homogeneous and heterogeneous). We compare our results obtained by imaging with reference data from effective spectroscopic measurements on the same material and investigate the reproducibility of the spectral electrical properties in an imaging approach for different degrees of heterogeneity and different artificial soils and in dependence on the hydraulic state.
