Previous studies:•very simple bathymetry: linear slope + flat bottom,•Watts’s law of motion.
Questions:•Nonlinearity, dispersion – when and where?•Which NLD model is better?
Methodology:•Numerical modelling (SWE, Full model for potential flow)•Laboratory experiments

Now:From model bathymetry to «real» one
• The «reality» during the wave propagation• The «reality» in the law of landslide motion
From 1D simulation to 2D simulation • 2D effects in the law of landslide motion• 2D effects during the wave propagation
