Prediction of design water level due to storm surge at teh Seogwipo coastal zone in Korea

摘要

Seogwipo coastal region is known to develop coast tourist attractions and expand its harbor facilities, but this region is also more likely to get damaged by typhoons since it is affected by most of the typhoons coming into the Korean Peninsula. This study comprehended the characteristics of Jeju Island coastal areas by analyzing severe weather elements like a typhoon, and particularly reviewed design water levels by storm surge in Seogwipo Harbor. The design water level was calculated on the basis of frequency analysis results regarding extreme water levels, tidal residuals per hour and observed surges and numerical simulation-based surge heights in case of a typhoon attack, and this study also suggested problems that rapid climatic change aspects cannot be reflected recently. To solve such a problem, it is required to constantly maintain the related data and apply high-degree stormy surge numerical simulations-based plans to the present work.
