Subaqueous slope failures can evolve in various patterns. Whereas some slides run out and furtherevolve into highly mobile turbidity currents, others maintain a continuum-like structure and remainfrontally confined. The different failure modes impose different hazard scenarios, making anunderstanding of their origin crucial for reliable hazard assessments. Yet many of the factorscontrolling their post-failure behaviour remain not well understood. In this paper, a procedure ispresented for the analysis of the post-failure evolution of subaqueous landslides, using a coupledEulerian–Lagrangian finite-element analysis approach. The procedure is applied to analyse the StNiklausen slide in Lake Lucerne (Switzerland), providing a good prediction of observed landslidefeatures, without back-calibration of input parameters. The approach is further applied to investigatethe influence of controlling parameters, highlighting effects of different strength parameters, thesurrounding water and the slope stratigraphy and geometry on the landslide dynamics. The procedurepresented can be generally applied to predict the post-failure evolution of subaqueous landslides andfacilitates the extraction of the moving soil–water boundary, which can serve as source input fortsunami propagation modelling.
