      abstract     = {Landslides are one of the most important natural hazards
                      that endanger human life and infrastructure all around the
                      world. Landslides occur as a result of failure in the
                      mechanical balance within slopes. Failure may be initiated
                      by various causes including earthquakes or man-made
                      activities such as excavation that influence the stress
                      distribution. However, in many cases, landslides are induced
                      by rainfall due to the direct influence of subsurface
                      hydrological processes on the mechanical balance of soils.
                      In particular, changes in water content of the soil because
                      of infiltration alter the matric suction and weight of the
                      slope material and therefore the effective stress
                      distribution and slope stability. In the past decades,
                      different hydromechanical models have been developed to
                      consider the interaction between soil hydrology and soil
                      mechanics for slope stability predictions. Available models
                      have typically considered a range of simplifying assumptions
                      to lower the computational costs and increase the numerical
                      robustness of the simulations. For example, many models only
                      consider a one-way influence of hydrological processes on
                      the mechanical status of a soil and feedbacks from soil
                      mechanics to hydrology are ignored. In addition, the actual
                      twophase flow system of water and air is commonly replaced
                      with a one-phase flow system by ignoring the variation in
                      pore air pressure. Moreover, most of the available models
                      that couple hydromechanical processes use 1D or 2D
                      representations of subsurface flow, which may lead to an
                      overly simplified representation of hydromechanical
                      processes in the case of more complex subsurface layering.
                      Finally, many models use simplified limit-equilibrium
                      methods to analyze slope stability despite known
                      limitations, such as the need to assume a failure surface a
                      priori. Recently, fully coupled hydromechanical models have
                      been developed that overcome the above-mentioned
                      simplifications in the modeling of coupled hydromechanical
                      processes. A state-of-the-art coupled hydromechanical
                      modelling approach for slope stability analysis is based on
                      the Mohr-Coulomb concept, which allows to evaluate the
                      stability at each point within a hillslope using the
                      so-called Local Factor of Safety (LFS) approach. [...]},
