Assessment of Slope Soil Movement Rate from Tree Trunk Deformation

Popis výsledku v původním jazyce

Tree trunk deformation can be related to the occurrence of soil movement on slopes. Hence, the deformation of tree trunks is a continuous record of soil movement rates on slopes during tree development. The present study explains why this phenomenon occurs and shows an approach to assess the soil movement rate extracted from tree trunk deformation. This approach does not require time-consuming measurements or costly technical support, it simply maps the deformation curve of the tree trunk. This method provides the average value of soil movement rates on slopes from the past to the present. The estimation of the soil movement rate is practicable only if the last accretion of a treetop crown fully sets off changes in tilting the trunk caused by soil movement on the slope and maintains a vertical direction. This condition applies usually to small and long-lasting permanent soil movement, which is hard to record with other available techniques.
