In: Lee, J.L.; Suh, K.-S.; Lee, B.; Shin, S., and Lee, J. (eds.), Crisis and Integrated Management for Coastal and Marine Safety. Journal of Coastal Research, Special Issue No. 114, pp. 226–230. Coconut Creek (Florida), ISSN 0749-0208. In this study, a wave overtopping prediction system was established for 10 major ports adjacent to 10 testbeds in South Korea, and a qualitative assessment of the system's reproducibility was performed through field surveys. The system estimates the probability of wave overtopping hazards, which is required for responding to disasters caused by swell-like waves. Wave overtopping prediction requires information on artificial structures in the major ports near the testbeds, swell-like wave predictions, and wave overtopping rate calculations. The threshold for defining wave overtopping hazards that can affect the hinterland, facilities, and residents in coastal areas was set to 0.01 m³/s/m, in accordance with EurOtop standards (Pullen et al., 2018) and the Korean Ministry of Oceans and Fisheries. The results of this study can be used to facilitate decision-making by providing qualitative estimations of wave overtopping hazards at various levels. By comparing the results to standard values, the risk of swell-like waves in testbeds along the East Sea coast can be determined. The proposed system can be used to avoid casualties and property damage in the event of a wave-overtopping disaster. [ABSTRACT FROM AUTHOR]
