Contrasting landslide activity on slopes with different structural geology: evidence from dendrogeomorphic analysis
Original language description
Slope movements are one of the most widespread geomorphic processes and can cause material damage due to their rapid and unpredictable action. The structural-geological conditions of the slope can play an important role in the resulting activity of landslide movements, and their type and mechanism. The environments in which slopes with different structural-geological structures regularly occur are cuesta. In order to define landslide activity on slopes with different structures, it is necessary to know their detailed historical behaviour. In this study, dendrogeomorphic methods were used to spatio-temporally reconstruct the activity of two landslides on slopes with contrasting structural-geological structure (bedding planes slope and escarpment slope) in the Hřebečský hřbet (Czech Republic) cuesta area. A total of 174 individuals of common spruce (Picea abies (L.) Karst.) were sampled using 348 increment cores. The internal structure and depth of the landslides on both slopes were analyzed using ERT (electrical resistivity tomography) geophysical measurements. The escarpment slope was affected by a rotational landslide that transitioned to a shallow plastic front at the base. Activity on this front was very high, which can be attributed to its heavy waterlogging, as confirmed by ERT measurements. Moreover, the chronological occurrence of landslide activity on this slope corresponded very well with the occurrence of above-average 3-day rainfall. In contrast, the slope on bedding planes was affected by rotational-translational landslide, which activity was significantly lower (four dated events in the last 80 years). Moreover, these events did not correspond to the occurrence of any pattern of above-average rainfall events. Thus, in this case, dendrogeomorphological analysis revealed distinct landslide behaviour on slopes with contrasting structural-geological conditions.
