In this study, a 3D numerical model for wave-induced seabed residual response with FD approximation is developed, which is an extended version of the model for oscillatory seabed response by Sui et al. (2016). A new definition of 3D source term f3 (for residual mechanism) is proposed which are based on the resultant force concept of shear stresses. The present model is validated with the flume tests available in the literature, and the relative good agreement is found. As an example, wave-induced dynamic seabed residual response around a mono-pile foundation is investigated.
