Study on Tsunami Simulation Method Including Building Shape, Collapse and Drift

Abstract

This paper presents a study on influences of computational conditions on numerical simulation of the building shape, collapse and drift in Tateyama city. The conventional tsunami simulation presents the influence of the building as a roughness. In this study, we studied in consideration of a shape, the collapse and drift of the building. The conventional tsunami simulation underestimates the inundation and velocity in some fronts and rear place of building group. Even if the shape of building is considered in the simulation, inundation is underestimated behind the building, when collapses of buildings are not taken into consideration. In this study, the consideration of the condition of the building is important and cannot ignore the influence of collapse and drift on calculating Tsunami simulation.
