Numerical simulation of waves generated by landslides using a multiple-fluid Navier–Stokes model
a r t i c l e i n f o This work reports on the application and experimental validation, for idealized geometries, of a multiple-fluid Navier–Stokes model of waves generated by rigid and deforming slides, with the purpose of improving predictive simulations of landslide tsunamis. In such simulations, the computational domain is divided into water, air, and slide regions, all treated as Newtonian...
متن کاملNumerical Modeling of water-waves induced by landslides with WC-MPS method
The rapid movement of sediments, which is often induced by a very erosive and transient flow in rivers and rivers, causes a lot of geomorphology and engineering problems. Failure of the dam with a moving bed, submerged landslide, sedimentation flushing in reservoirs are just a few examples of these problems. The study of waves is challenging due to the interference of several complex physical p...
متن کاملEvolution of water waves generated by subaerial solid landslide
Waves generated by aerial and subaerial landslides are studied experimentally, theoretically and numerically. A set of experiments are done in a wave tank of 18 m long, 0.65 m wide and 1.5 m deep. Numerical simulations are in good agreement with the experiments. Based on numerical and experimental results, we derive different scaling laws which show a good agreement with the experiments and the...
متن کاملBoussinesq modeling of surface waves due to underwater landslides
Consideration is given to the influence of an underwater landslide on waves at the surface of a shallow body of fluid. The equations of motion which govern the evolution of the barycenter of the landslide mass include various dissipative effects due to bottom friction, internal energy dissipation, and viscous drag. The surface waves are studied in the Boussinesq scaling, with time-dependent bat...
متن کاملModelling Combined Subaerial-Subaqueous Flow-Like Landslides by Cellular Automata
Macroscopic Cellular Automata characterize a methodological approach for modelling large scale (extended for kilometres) complex acentric phenomena, e.g. surface flows as lava flows, debris flows etc.. This paper concerns the extension of such a method in order to simulate combined subaerial-subaqueous flow-like landslides. The occurrence of heterogeneous interacting processes requires a more p...
