The equilibrium stages of headland-bay beaches in the coastal provinces of Vietnam

Tóm tắt

     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 predicted. Phan Thiet beach is a dynamic equilibrium; Hon Rom beach is a static equilibrium. As for Ninh Thuan, Phan Rang beach is not an equilibrium beach. If the jetty in the downdrift of Phan Rang beach were constructed, the beach would be stabilized.
