In order to evaluate destruction due to tsunami, structures with soil structure such as coast levee, it is essential to establish coupled analysis of fluid and ground. Arikwa(2017) developed coupling model that performs weak coupling method of fluid and ground. When using such a model, it is necessary to match seepage on fluid and ground. In this study, we constructed model applying the Dupuit-Forchheimer to fluid analysis. And compare it with experiments and verify validity of the model. Experiment and calculation in good agreement with seepage flow velocity and pore water pressure, and validity of this method could be confirmed.
