A sediment transport model taking into account laminar and turbulent resistance force due to infiltration/exfiltration is proposed in this study. A three-dimensional two-way coupled fluid-structure-sediment interaction model (FSSM) combined with the proposed model is applied to sediment transport in a steady uniform flow and local scouring due to tsunami run-up. As a result, the laminar resistance force due to infiltration/exfiltration affects the sediment transport rate, and it is consequently essential to take into account the laminar resistance force in assessing sediment transport in the presence of infiltration/exfiltration. The results also show that the FSSM with the proposed model predicts experimental data reasonably well, and demonstrate the validity of the FSSM with the proposed model.
