Abstract

A long wave model with nesting scheme is widely used for tsunami simulation and impact assessment, generally. The conventional nesting scheme, however, has disadvantages for analyzing larger computational mesh size along the coast and needs expensive computation costs. Adaptive Mesh Refinement (AMR) method can consider the interactions of different grids and reduce computational cost together. This study applied the AMR for calculation of long wave propagations, and the different mesh refinement schemes were applied and optimized by a series of numerical experiments. The model was applied to the 2011 Tohoku Earthquake Tsunami, and the model was validated against the post tsunami inundation survey data.
