The Tsunami caused by the 2011 Tohoku-Pacific Ocean Earthquake wreaked enormous damage on coastal area. Numerical computation model which can simulate Tsunami propagation, run-up and inundation with high accuracy is required. In this paper, the two dimensional CRD (Contour-integration-based Residual Distribution) scheme which is numerical computation to simulate the flow with shock waves is applied for run up and inundation of the 2011 Tohoku-Pacific Ocean Earthquake Tsunami in the Ishinomaki city and the Kitakami River. This paper shows that CRD scheme can evaluate the propagation velocity and wave height of Tsunami in the sea, the river and the inundation area.
