In recent years, rising sea levels due to global warming and climate change, as well as an increase in high waves and swells caused by typhoons or strong winds, have raised concerns about coastal disasters such as wave overtopping and coastal erosion along the coasts of the Korean Peninsula. Recently, marine ICT convergence technology has been developed that replicates the real world (physical world) identically in virtual space and predicts the simulation results using a digital twin integrated with an artificial intelligence system. The Coastal Disaster Simulation System (CDSS), based on a geospatial digital twin cloud web 3D GIS system, has been developed to predict coastal disasters such as typhoons, storm surges, high waves, wave overtopping, flooding and beach erosion using real-time monitoring data and numerically predicted results. The CDSS performs scientific analyses such as typhoon track analysis, damage analysis to coastal facilities within the storm induced hazard radius, storm surge damage area analysis, overtopping discharge analysis, inundation area analysis and coastal erosion analysis. To determine the area and depth of flooding or inundation caused by typhoon storm surges or overtopping discharges, this system uses the Eurotop Overtopping Manual (2018) to calculate the wave overtopping volume and performs an analysis based on the relative elevation of the coastal terrain at that time. This system is expected to contribute to the prevention of coastal disaster and support the establishment of a coastal disaster prevention decision-making system.
