Abstract
In this study, tsunami drifts analyses considering effects of the structures such as buildings and tsunami barriers are carried out. The model of drift simulation can consider the interaction between tsunami drifts and tsunami propagation. This model is based on 2-dimensional tsunami simulation model, and can also be considered behavier of the tsunami drifts at a wide variety of situation. As for the numelical example, this simulation model is applied for a analysis of tsunami drifts around a building which is to estimate the validity of model. This model is also applied to the drift simulation which has a variety of tsunami drifts and structures such as buildings and tsunami barrtiers. From the results of numerica example, it is shown thate the model can estimate a wide variety tsunami drifts behavior by using extended tsunami simulation model.
