Adaptive Mesh Refinement (AMR) method can consider the interactions of different grids and reduce computational cost compared with the conventional nesting scheme. This study applied the AMR for calculation of long wave propagations, and the mesh refinement scheme was optimized through the numerical experiments. The application of the developed model to the 2011 Tohoku Earthquake tsunami was carried out, and the validity of model was vaildated against the survey data. As a result, AMR method could decrease the computational cost, while maintaining the computational accuracy.
