A 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.
