Abstract: Beach erosion is a natural process that occurs when conveying sediment away from the shoreline is not balanced by depositing new material on the shoreline. This is a problem that is causing beach areas to decline. To avoid beach erosion and flooding, a sea wall and groin have been built. Shoreline evolution prediction is used to inves¬tigate the beach topography in the future. There are three phenomena give a large effect to the coastal structure such as the erosion, the accretion and the water level changes. To investigate of beach erosion and beach deposition is needed qualitative understanding of idealized shoreline response to the governing process. The first part of this research we introduce a governing equation of a one-dimensional shoreline evolution model when a couple of groins is added. The manipulation of physical pa¬rameters for the model is introduced. The setting method of the initial condition and the boundary conditions techniques when a couple of groin structure effect are also proposed. The proposed simulation can be used to predict the efficiency of a groin system construction in a local beach. The second part of this research, we present a one-dimensional mathematical model of shoreline evolution, and the parameters that influence this model are described monthly over a period of one year. Consideration is given to the wave crest impact model for evaluating the impact of the wave crest at that stage. It focuses on the evolution of the shoreline in environments where groins are installed on both sides. The initial and boundary conditions setting techniques are proposed by the groins and their environmental parameters. The non-uniform influence of the crest of the breaking wave is so often considered
