A Shoreline Evolution Model with a Groin Structure under Non-Uniform Breaking Wave Crest Impact

Beach erosion is a natural phenomenon that not compensated by depositing fresh material on the shoreline while transporting sand away from shoreline. There are three phenomena have serious influence coastal structure, such as increases in flooding, accretion, and water levels. In addition, prediction of evolution used to investigate topography beach. this research, we present one-dimensional mathematical model evolution, parameters described monthly basis over period one year. Consideration given wave crest impact for evaluating at stage. It focuses environments where groins installed both sides. The initial boundary condition setting techniques proposed their environmental parameters. non-uniform breaking so often considered. We then traditional forward time centered space technique Saulyev finite difference estimate each
