The mesh size and time increment, other than the CFL condition, essential to obtain tsunami run-ups with sufficient accuracy for practical applications are examied. It is found that more than 20 spatial grid points should be included within a local wave length for obtaining reasonable wave height. This criterion is applied to a numerical simulation of the Nihonkai-Chubu earthquake tsunami in 1983, the measured run-up heights and inundated areas of which supply plentiful data for comparison. The present computation reproduced very well the spatial distribution of tsunami run-ups and those maximum values. キーワード(英): - 記事区分 - 区分     論文集
