FAQ/ Calculation of Flooding by Tsunami River Run-up

Is it possible to simulate the phenomenon of a river moving up a tsunami and the accompanying flooding phenomenon?


It's possible.

However, since first-precision windward differences are used to differentiate the advection terms of river models, the influence of numerical diffusion cannot be ignored in fast flows. For full-scale evaluation, we believe that a more accurate differentiation method should be applied.
