Abstract

The aim of this study is to document the use of a time-series of orthophoto information since 1951 to support a dendrogeomorphic analysis of debris flows on a highly active cone in the western Austrian Alps, and to highlight the effect of severe tree loss on reconstructed tree-ring analysis. The study investigated the Bärenrüfe torrent located in the province of Vorarlberg. Based on 3 annual field observations, it is evident that this catchment produces very frequent and small debris flows with minor material relocation. The specific challenges of tree-ring analysis in this tree species and in highly active environments are explicitly addressed in the discussion and underline the necessity of employing complementary methods of analysis in an integrative manner
