| Zusammenfassung |
| A numerical model based on the mild slope equation, suitable to reproduce the
propagation of small amplitude tsunamis in the far field, is extended to
reproduce the generation and the propagation of waves generated by
landslides. The wave generation is modeled through a forcing term included in
the field equation, which reproduces the effects of the movement of a
submerged landslide on the fluid. The measurements of three dimensional
laboratory experiments, which simulate tsunamis generated by landslide
sliding along the flank of a conical island, are compared with the
theoretical calculation results. The present approach is also compared with
the similar method of Tinti et al. (2006) used for the generation of these
waves in depth integrated model, and the different behavior when using
frequency-dispersive and non-dispersive equations is highlighted. |
