ABSTRACT: In eastern Canada, superficial landslides are a frequent type of landslides in clay slopes. On April 27, 2019, such a landslide occurred in Deschaillons-sur-le-Saint-Laurent along the Saint-Laurent River in Québec. To investigate the post-failure impact force of this case, a model based on the Material Point Method (MPM), MPM-PUCRio, and another based on Smoothed Particle Hydrodynamics (SPH), DAN3D, are used in this study. The pre- and post-failure surfaces used in the models are generated from available Digital Elevation Models (DEM). The clay material that constitutes the sliding mass is considered viscoplastic and is simulated using the Bingham model. The results from the MPM-PUCRio software are compared with the results from the DAN3D software in order to define and validate the impact force estimation for the Deschaillons superficial landslide.
