Abstract

A multidisciplinary methodology based on the analysis of slope systems was used for researching the present and past dynamics of 2 hillslopes. Using the results of direct dilatometric monitoring, GPS field mapping, sedimentology, geodetic measurements and DEM analyses, several common rules have been observed for the behaviour of 2 model localities and a likely polycyclic development established, with recurrence of mass-wasting cycles related to material supply thresholds. Radiometric dating of debris flow activity showed that the cycles span approximately 4000 years. In this area of rather stable bedrock conditions, at least 2 factors that decrease slope stability need to act together to activate slope processes: i.e. a favourable structural predisposition (dip of major joint or bedding planes) and an increase in relief through either glaciation or river incision
