Landslide-generated tsunamis are a relevant source of hazard for coastal areas. In this paper, the preliminary modelling results of tsunamis generated by deformable landslides by using computational fluid dynamics (CFD) methods, in OpenFOAM®, is presented. The numerical approach presented here consists in modelling the granular material by using a Coulomb viscoplastic rheology. This numerical model is applied to reproduce three literature benchmark cases (2D submerged, 2D and 3D subaerial, respectively). Some preliminary qualitative and quantitative numerical results, compared to the experimental ones, are presented in the paper.

Abstract
Landslide-generated tsunamis are a relevant source of hazard for coastal areas. In this paper, the preliminary modelling results of tsunamis generated by deformable landslides by using computational fluid dynamics (CFD) methods, in OpenFOAM®, is presented. The numerical approach presented here consists in modelling the granular material by using a Coulomb viscoplastic rheology. This numerical model is applied to reproduce three literature benchmark cases (2D submerged, 2D and 3D subaerial, respectively). Some preliminary qualitative and quantitative numerical results, compared to the experimental ones, are presented in the paper.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
