To provide a computational framework for simulating fluid-sediment-seabed interactions, a three-dimensional coupled fluid-sediment-seabed interaction model is developed and applied to seabed response under regular waves and local scouring from tsunami run-up. For the seabed response under regular waves, the computational capability of the model is demonstrated from comparison with analytical solutions in terms of pore-water pressure and the displacement of the seabed skeleton. For the local scouring from tsunami run-up, numerical results show that the model can compute the seabed response during the onset of the local scouring, and suggest that the model is a useful tool for analyzing and evaluating a general complex fluid-sediment-seabed interaction phenomenon in the marine environment.
