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 human life. In this research, we used tree-ring width analyses quantify the response trees three debris flow events in NW Slovenia (Javoršček, Srpenica) W (Nikova) for which know time origin. We attempted date these similar tree responses past compared patterns between different species. Altogether, sampled 147 across range species (Fagus sylvatica, Pinus sylvestris, Fraxinus excelsior, ornus, Acer pseudoplatanus, Picea abies, Juglans regia, campestre, Tilia cordata Ostrya carpinifolia), including reference that were outside fan. For 91 trees, constructed chronologies pointer-year analysis identify years had abnormal growth. remaining (mostly carpinifolia, pseudoplatanus), either could not accurately distinguish rings or two samples from single showed significantly growth patterns. The Fagus sylvatica abies following weak at Javoršček site no clear other sites. Tree responded similarly same locations. Due lack pattern, able reconstruct flows.
