Simulation on 2D underwater landslide-induced tsunamis

The Green-Naghdi (GN) theory is used here to simulate two-dimensional (2D) underwater landslide-induce tsunamis. Finite difference method is used to solve the GN equations. GN theory has different levels. There are GN-1, GN-2, ⋯, GN-K theory in GN theory. When K goes up, the GN equations will be more complicated, and the results will be more accurate. For the case simulated here, results of GN-5 theory are better than results of GN-3 theory. GN-7 results are almost the same as GN-5 results. That means GN-5 results are the converged results from GN theory. GN-5results agree well with other's experimental results.
