A017 USING RESISTIVITY MEASUREMENTS FOR DAM SAFETY EVALUATION AT ENEMOSSEN TAILINGS DAM 1 SJÖDAHL P.* DAHLIN T.* JOHANSSON S.** * Dept. of Engineering Geology Lund University Box 118 221 00 Lund Sweden pontus.sjodahl@tg.lth.se torleif.dahlin@tg.lth.se ** HydroResearch Sam Johansson AB St. Askens väg 6 183 65 Täby Sweden sam.johansson@hydroresearch.se INTRODUCTION Internal erosion is one of the major reasons for embankment dam failures. Resistivity measurements may have the possibility of detecting internal erosion processes and anomalous seepage at an early stage before the safety of the dam is at stake. The technique is essentially non-destructive which is particularly important when working with
