First dendrogeomorphological dating of DSGSD: specificity of the reconstruction

Popis výsledku v původním jazyce

Globally, one of the most widespread types of slope deformation is DSGSD (deep-seated gravitational slope deformation), which typically takes tens of thousands of years to develop, but can also be catastrophically reactivated and may represent a recent natural hazard. Knowledge of their past evolution is based mostly on absolute dating of old whereas recent evolution can be covered by appropriate monitoring. Bridging these two time periods is currently a major challenge. This study thus presents unique dating of DSGSD evolution using dendrogeomorphic (tree-ring-based) methods over the last 60 years. The uniqueness of the study also lies in the origin of DSGSD, which was anthropogenically induced through deep lignite mining that began in 1962. Tree-ring-based data from 71 disturbed trees (<jats:italic>Fagus sylvatica</jats:italic> L. and <jats:italic>Larix decidua</jats:italic> Mill.) revealed the specific effects of DSGSD movements on the growth of both tree species, which are usable in future research. At the same time, the obtained chronology of movements revealed the occurrence of initial failure of DSGSD and their subsequent cessation, except for one part of the studied slope, in which there is a simultaneous recovery of movements. The dendrogeomorphic analysis confirmed the generally assumed evolution of DSGSD but in a very limited time period, which may be related to the anthropogenic influence on its formation. The research was complemented by an analysis of the dynamics of post-failure evolution of landforms based on anatomical data from exposed tree roots. The results suggest rapid erosional modelling of the newly formed DSGSD.
