Dendrogeomorphological analysis of the evolution of slope processes on flysch rocks (Vsetínské vrchy Mts; Czech Republic)

Popis výsledku v původním jazyce

Slope movement and gully erosion represent important slope-modelling processes. In a selected locality within Vsetínské vrchy Mts. we have investigated a landslide area via 73 cross sections from Picea abies and Larix decidua and a gully network via 21 cross sections from exposed roots. The analysis was carried out on the basis of tree-ring eccentricity, reaction wood formation and anatomic changes on root cells. We reconstructed a 15-year-long series of landslide movement and a 40-year-long series of erosion events. Only slight dependence was proved between reaction wood formation and treering eccentricity. The years 1997, 2002 and 2006 were evaluated as the years of the most pronounced landslide activity. Dendrogeomorphology revealed 12 erosion events. Steep slopes of the gullies were dominated by upward erosion, whereas less steep concave parts showed upward erosion alternating with downward erosion.
