The study presents the application of parabolic model using MEPBAY package to estimate the equilibrium stages of the headland-bay beaches in Binh Thuan and Ninh Thuan provinces. The model results showed that the present shorelines in Phan Thiet, Binh Thuan are not under equilibrium stages. As for Binh Thuan, the shoreline changes with and without structures in Phan Thiet and Hon Rom beaches were predicte.
