Can we use dendrogeomorphology for the spatial and temporal analysis of less intensive mass movement processes?: A case study of three debris flows in NW and W Slovenia

Debris flows can transport large amounts of material and therefore present a significant threat to infrastructure and human life. In this research, we used tree-ring width analyses to quantify the response of trees to three debris flow events in NW Slovenia (Javoršček, Srpenica) and W Slove...
