Abstract

Adaptive mesh refinement (AMR) is one of the powerful computational tools to enhance local computing resolution at less cost. In this paper, computational performances of AMR for tsunami computer simulations were examined in terms of the accuracy and computational cost through computational tests for long wave propagation initiated by collapse of a water column on still water. AMR was also applied to a practical tsunami evolution - 2003 Tokachi-oki earthquake tsunami, which was compared with observed water elevation for examining the applicability of this method to practical tsunami events. It was found through the numerical tests that the present method is capable of efficiently performing reliable computations of tsunami propagation at high resolution.
