Hydraulic Conductivity Estimation from Spectral Induced Polarisation Data – A Case History

P035 HYDRAULIC CONDUCTIVITY ESTIMATION FROM SPECTRAL INDUCED POLARISATION DATA – A CASE HISTORY Abstract 1 We carried out a spectral induced polarisation (SIP) survey at the Krauthausen hydrogeological test site in Germany. Data were recorded along three profiles with a dipoledipole configuration and 4 m electrode spacing. The data were inverted with a 2-D inversion code to obtain images of resistivity and phase distribution for each frequency. From the complex conductivity distribution we calculated the hydraulic conductivity using different empirical equations. The results are encouraging in the sense that the hydraulic conductivities have the same order of magnitude as those
