      abstract     = {Bedrock topography is known to affect subsurface water flow
                      and thus the spatial distribution of pore water pressure,
                      which is a key factor for determining slope stability.
                      Therefore, the aim of this study is to investigate the
                      effect of bedrock topography on the timing and location of
                      landslide initiation using 2D and 3D simulations with a
                      hydromechanical model and the Local Factor of Safety (LFS)
                      method. A set of synthetic modeling experiments was
                      performed where water flow and slope stability were
                      simulated for 2D and 3D slopes with layers of variable
                      thickness and hydraulic parameters. In particular, the
                      spatial and temporal development of water content, pore
                      water pressure, and the resulting LFS were analyzed. The
                      results showed that the consideration of variable bedrock
                      topography can have a significant effect on slope stability
                      and that this effect is highly dependent on the intensity of
                      the event rainfall. In addition, it was found that the
                      consideration of 3D water flow may either increase or
                      decrease the predicted stability depending on how bedrock
                      topography affected the redistribution of infiltrated
                      water.},
