Nowadays, there are many methods to study shoreline change in coastal engineering. Among them, mathematical methods are considered as effective ones that have been used for a long time. LITPACK is a numerical model in MIKE software package, developed by Danish Hydraulic Institute (DHI), for simulating non-cohesive sediment transport in wave and currents, littoral drift, coastline evolution and profile development along quasi-uniform beaches. In this paper, the authors apply the model for studying shoreline change in Cat Hai Island, Hai Phong City. Cat Hai is a famous island with dense population working with various coastal - tradition works locating at the centre of Hai Phong, where ...
