Tree ring based estimation of landslide block displacement: Evaluation of a new experimental approach

Popis výsledku v původním jazyce

The mechanisms and velocities of landslide movements are important information for assessing hazards associated with landslides. This contribution introduces a new approach in reconstructing the past rate of landslide displacement using dendrogeomorphic methods. The principle of this method is based on the analysis of exposed roots in tension cracks or scarps of active landslides. The identification and dating of anatomical changes in root ring series in various root segments, induced by gradual root exposure due to crack spreading, enable the estimation of the rate of root exposure and the calculation of the displacement rate of landslide blocks. We analysed anatomical reactions of 87 root cross sections in tension cracks of an active landslide the Morayskoslerske Beskydy Mts. in the Outer Western Carpathians. Microscopical analysis of microcuts from cross sections showed the reduction in the earlywood vessel sizes, indicating the year of root exposure.
