Numerical modeling of waves for a tsunami early warning system

Numerical modeling of waves for a tsunami early warning system
carried out in a wave tank of the Ocean Engineering Department at the
University of Rhode Island, USA. In their model the landslide is reproduced
with a smooth and streamlined rigid body which slides down a plane slope,
starting from different underwater positions. They have carried out a detailed
study of the law of landslide motion and relative discussions about the
generated waves features.
With regard to the landslide generated tsunami, the works of Di Risio
et al. (2009a; 2009b) need to be mentioned even because were used in the
present work to validate the numerical model. The paper of Di Risio et al.
(2009a) describes three dimensional laboratory experiments carried out at the
Environmental and Maritime Hydraulic Laboratory (LIAM) of the University
of L’Aquila, Italy, and reproduce a rigid landslide body sliding on a plane
slope. The paper of Di Risio et al. (2009b) describes other three dimensional
experiments which simulate an equal landslide body sliding down the flank
of a conical island, builded in the middel of a large wave tank. This physical
model is built at the Research and Experimentation Laboratory for Coastal
Defence (LIC), of the Technical University of Bari, Italy. More details about
both physical models are given in sections 4.4 and 4.5 where their results are
used to validate the numerical model.
