Topographic change of an artificial shallow is investigated using a fluid-sediment interaction model combined with a sediment transport model considering pore-water pressure in the surface layer of the seabed. From a comparison with hydraulic experiments, it is demonstrated that the model can predict experimental data reasonably well in terms of water surface fluctuation, flow velocity, and pore-water pressure. Numerical results of the topographic change of the shallow show that pore-water pressure has a reducing effect on sediment transport and resulting topographic change from the upper part of the slope to the crown of the shallow, and demonstrate that the predictive capability of the model for the topographic change of the shallow is improved by the consideration of the pore-water pressure in the sediment transport model.
