In this study, we compared three-dimensional numerical models with the experimental result of tsunami with large-scale eddy. The employed general-purpose models were OpenFOAM, CADMAS-SURF/3D (CS3D), and T-STOC, which have been often used in coastal and ocean engineering. First, we examined the validation of OpenFOAM changing the difference scheme of advective term which effects calculation accuracy. We confirmed that higher-order difference scheme is important for calculation stability and accuracy, and introduced the second-order upwind difference scheme into CS3D and T-STOC. The three models was recognized to reproduce the hydraulic experiment on tsunami eddy appropriately
