Implication

Laboratory experiments reveal surface roughness and particle shape affect tsunami wave generation in landslides, highlighting disaster prevention needs.

Key Points

The central aim is to investigate the effects of granular material properties on tsunami generation from landslides.
Conducted 43 2D flume experiments with gravity-accelerated granular slides.
Utilized granular materials with varying surface roughness and particle shapes.
Maintained a consistent slope angle of 30 degrees for all experiments.
Rough materials significantly reduced slide impact velocity and maximum wave amplitude compared to smooth glass beads.
Larger wave amplitude reduction observed for rough materials with non-uniform grain size distributions.
Minor variations in surface roughness showed negligible impact on wave amplitude along the flume.
