Abstract

Smoothed particle hydrodynamics (SPH) is used to simulate both two and three-dimensional cases of tsunami generation and propagation. A combined SPH-LES type scheme or sub-particle scale (SPS) scheme is used to describe viscous effects. Results for 2-D compare well with other nonlinear numerical models in the case of a 2-D landslide-generated tsunami. The application of the 2-D model to the 3-D landslide problem is shown to be inappropriate, necessitating a fully 3-D model. However, the resolution required for 3-D is beyond the current capabilities of the JHU-SPH code necessitating high performance parallel computing.
