영문 초록

With global warming, sea level rise is occurring along the coast of the Korean Peninsula and in island areas such as Ulleungdo. Rising sea temperatures supply more energy for tropical low-pressure system formation and increase wave energy invading the coast. As a result of increased typhoon intensity, various methods have been proposed to calculate design forces in coastal structure design. The Ministry of Oceans and Fisheries (2019) provides long-term wave output time series for the coast of Korean Peninsula. The time series dates from 1979 to 2019 and provides deep-water design waves for frequencies (10 years, 20 years, 30 years, 50 years, 100 years) at coastal grid points. Water level calculation is crucial for coastal structure stability and design wave calculations. Numerical models enable the estimation of wave distribution where measurement is challenging, and water level calculation within the model is vital for wave height and monthly volume calculation near the coast and structures due to wave deformation factors. This study aims to provide necessary design data by examining changes in still water level experiments according to design water level calculation methods proposed in port and fishery design standards in the Ulleungdo area where water level changes due to various weather and currents are greater those caused by tides.
