Abstract
Landslides in reservoirs constitute one of the main threats to dams. Although they are not frequent, they may generate severe damages in the population and goods placed near the shores. It is a complex phenomenon, because of the interaction between the landslide, the still water in the reservoir, and the dam. The Particle Finite Element Method (PFEM) is an innovative numerical scheme which combines a lagrangian approach with the resolution of FEM equations via mesh generation. After running some validation cases, Lituya bay rock slide has been simulated in 3D, in which 90 × 106 tons of rocks fell on the bay, generating a wave that caused a maximum run-up of 524 m on the opposite shore. The results show that PFEM is a useful tool in risk assessment related with this phenomenon, because it gives a good approximation to the potential affections, thus allowing the appropriate design of protection measures.
