In this paper, the authors carried out numerical simulations of tsunami-induced topography change around a harbor using various sediment transport formulas in order to clarify the effect of the difference in the formulas on the analysis. A full three-dimensional flow model was adopted for the tsunami calculation. According to the simulations considering only bed-load, we could see that non-equilibrium bed-load transport affected to the sedimentation in the harbor. Moreover, by comparisons between the targeted experimental result and the simulated results using various suspended-load formulas considering non-equilibrium bed-load transport, the Ikeno et al. formula and the Itakura and Kishi’s formula were found to reproduce the experimental result well under the calculation condition we set in this paper.
