A Study on the Shoreline Movement of Won-pyeong Beach using ShorelineS Model

Abstract

Increased coastal human intervention and climate change are leading to rapid changes in coastal areas and often causing catastrophic damage to resident populations. The ShorelineS model was introduced, which can explain drastic beach changes were simulated. According to the modeling results, the installation of Gungchon Port caused rapid sedimentation in the south of the port. It was reviewed that the erosion and sedimentation tendency of the beach is changed after the installation breakwater in front of the beach, the erosion in the central part of the beach was somewhat suppressed, and the beach was deposited in the shape of tombolo on the back of the beach. The installation of artificial structures dramatically changes the equilibrium state of the beach and increases the erosion of the direct wave near the structure. The ShorelineS model was the advantage of being able to properly reproduce changes in the coastline by inputting relatively simplified environment and beach information and to quickly predict after installation of artificial structures. The reallity, coastline changes due to various causes, so follow-up studies are needed to predict and effectively respond to this through an advanced model that reflects various conditions.
