| Zusammenfassung |
| In this work we present some real applications of the two-layer Savage-Hutter type model
developed by E. D. Fernández-Nieto et al (JCP, 2008) to study submarine avalanches. In this
model, a layer composed of fluidized granular material is assumed to flow within an upper
layer composed of an inviscid fluid (e. g. water). The model is derived in a system of local
coordinates following a non-erodible bottom and takes into account its curvature, and it is
discretized using a two dimensional high-order finite volume scheme implemented on GPU
cards for increasing the speed-up.
Simulation of a paleotsunami occurred in the Alboran Sea is presented focusing on its
coastal impact. Besides some comparisons with laboratory experiments of submarine and
sub-aerial avalanches will be presented. |
