| Summary: | The casualties and the inevitable losses from the tsunami disaster make the
development of a warning system and wave attenuator indispensable. In this case,
simulation using a mathematical model can be one of the main considerations. This
study wants to see how submarine landslides are able to propagate tsunami waves
and estimate the maximum wave height using a mathematical model approach. The
model used is based on the non-linear shallow water equation, which is then solved
numerically using the finite volume method on a half grid. We also derive an
analytical solution using the Laplace-Fourier transform to validate the model as
well as study the tsunami phenomenon due to submarine landslides on a flat bottom.
The numerical scheme of the model used is then validated by simulating and
comparing the results with experimental data, use of other models, and analytical
solutions. After validating, the scheme is then used to simulate a tsunami by a sea
floor landslide on the Palu Coastal topographic data. The simulation gave very good
results, so that it was able to estimate the maximum amplitude of the Palu tsunami
in 2018 based on the data. |
