Storm surge analysis in the Korean Peninsula

Abstract

The precise forecasting of the storm surge in terms of height and peak time is getting important as the coastal areas have been widely developed around world. The Korean Peninsula has been experienced more than 2 typhoons in every year. In this study the statistical analysis of storm surge is explored using the sea level data by the Korea Hydrographic and Oceanographic Administration (KHOA) from 1959 to 2012. A proper method (Lee et al, 2009) was applied to calculate the storm surge heights from the measurements, because the storm surge height can be varied with the measured data (with record interval and length) and the tide analysis method (harmonic or response method).Among 48 landed typhoons in the Korean Peninsula, the highest storm surge in the record was 2.1 m at the Masan during typhoon MAEMI in 2003. The southwestern part of the Korean Peninsula experienced (and recorded) relatively more storm surge events. For instance, Mokpo which is a city in the southwest part in the Korea, recorded 35 storm surge events (above 0.5 m of storm surge height). Other statistical analysis was investigated such as storm surge arrival time with the tidal phase which is one of important information for the coastal disaster prevention.this study the statistical analysis of storm surge is explored using the sea level data by the Korea Hydrographic and Oceanographic Administration (KHOA) from 1959 to 2012.
