abstract = {Rainfall-induced landslides are one of the most important
natural hazards that endanger human life and
infrastructureall around the world. Different model concepts
have been developed to consider the effect of soil
hydrologyon the mechanical balance and to predict the
stability of hillslopes. One state-of-the-art modelling
approach forcoupled hydromechanical slope stability analysis
is based on the Mohr-Coulomb concept that allows evaluating
thestability at each point within a hillslope using the
so-called Local-Factor-of-Safety (LFS) approach. However,
theLFS approach has so far mainly been used to analyze in
silico experiments with relatively simple slope
geometry.Therefore, this study aims to apply the LFS concept
to a slope with complex morphology and spatially
distributedmaterial properties that are expected to have a
strong influence on flow orientation, water content, stress
distribution,and slope stability. Our study site is located
at Dollendorfer Hardt, Germany, and has been investigated in
arange of previous studies. The slope geometry was obtained
from a high resolution digital elevation model, andthe
subsurface layering was derived from geophysical site
characterization. The results of the
hydromechanicalsimulations will be compared to available
soil water content monitoring data obtained using a wireless
sensor networkand time-lapse electrical resistivity
tomography. In a final step, slope stability will be
evaluated for severalhypothetical rainfall scenarios to
determine conditions for potential slope movement.},
