The aim of this study is to develop the practical numerical analysis model of tsunami to reproduce run-up soliton fission waves in the river. We verify accuracy and the computing time about the developed model by using the large-scale flume experiment. It has been understood that scheme of advective term and evaluation of space grid size have an effect on numerical result. We study the evaluation of space grid size and the computing time necessary for the calculation of the run-up tsunami with a soliton fission waves in the river. In this study, numerical algorithm of the soliton fission waves proposed by Shigihara and Fujima(2007) is very useful to calculate practically.
