Contribution of a combined TDEM (Time-Domain Electromagnetism) and electrical survey to the investigation of the Super Sauze flowslide internal structure

The aim of this study is to determine an investigation protocol that permit s the Super Saute flowslide to be described along continuous lines, through the association of electrical and TDEM (Time-Domain Electromagnetism) meth ods. The transition from one resistivity range to another often corresponds to the three layer limits defined by geotechnical soundings. The results p resented show that the combined methods are well suited to the question inv estigated and that they are validated by the geotechnical data.
