dc.description.abstractA three-dimensional computational method based on multiphase modelling is employed to predict the behaviors of floating tsunami debris in coastal residential areas. The present computational method enables us to deal with the interactions between free-surface flows and the movements of floating objects, as well as the collisions among the objects and fixed structures. The present method was first applied to simple stability problems of floating cylinders and then it was applied to the 1/250 scale tsunami experiments. Finally, two types of numerical experiments were performed using larger number of floating objects in more compli- cated conditions. As a result, it was shown that the present method is effective to predict the behaviors of floating objects transported by tsunami between buildings on non-uniform grand surfaces.
