I did that with the linear wave equation, see ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-k9LIzXlkh98.html - but not yet with the nonlinear shallow water equation used here.
Interesting. Thanks for the application, but it does look rather basic. For example, does this simulation account for the actual depth, ocean floor topography, wave interference, curvature of the earth, water vs crater impact morphology? I wonder if AI could take a crack at this. My main concern is wave height impact along irregular mountainous coastlines and coastal valleys.
Wave interference is automatically accounted for, since this is a simulation of a (nonlinear) wave equation. The ocean depth is also taken into account, albeit with a limited resolution. The curvature of the Earth is accounted for, as the wave equation uses the Laplace operator on the sphere. The Coriolis force is modeled as well. The main limitation is the interaction with the continents, which is quite crudely modeled by a repulsive potential.
@@NilsBerglund Ah, I see. As well as higher resolution of seafloor/coastline data and modeling, we need better display of wave affected terrain, destruction zones, and metrics. Apophis, for example, 100 miles south off the coast of Hawaii
Note that this is a nonlinear wave equation, which takes into account, to some extent, the varying ocean depth. Light is usually modeled by the linear Maxwell equations, unless it is interacting with an extremely nonlinear medium.
Small thing about Hualien: it's a county in in east side of Taiwan. And earthquakes often occur in Hualien, especially from April 3rd this year till now. . On 3 April 2024, at 07:58:11 NST (23:58:11 UTC on 2 April), a Mw 7.4 earthquake struck 15 km (9.3 mi) south of Hualien city, and thousands of aftershocks have occurred since then.
@@NilsBerglund Just providing an idea. Maybe you can do something like earthquake simulation? Maybe not in Taiwan but in anywhere on earth that with plate faults on.
