Abstract: Nonlinear wave transformations take place due to the effects of bathymetry and coastline geometry. Several nonlinear transformations cannot be represented correctly in a phase-averaged model, a phase-resolved modeling strategy is often required. Shallow water equation-based phase-resolving models are computationally efficient, but their accuracy is limited by water depth conditions. In this article, a full nonlinear potential flow (FNPF) model REEF3D: : FNPF is used for the phase-resolving wave modelling near the Naissaar harbor. The accuracy of the FNPF model is not limited by the water depth and thus can model both the short wind-generated waves and the long waves under extreme events related to climate change. The holistic understanding of the hydrodynamic environment provides vital information for future investigations into the large-scale cross-shore and longshore sediment transport and morphology evolution in that region.
