Abstract

A numerical simulations were performed to investigate the storm surge during the passage of Typhoon Maemi on the coast of Busan. The typhoon landed on the southern coasts of Korean Peninsula at 21:00, September 12, 2003 with a central pressure of 950 hPa, and the typhoon resulted on the worst coastal disaster on the coast of Busan in the last decades. Observed storm surges at Busan, Yeosu, Tongyoung, Masan, Jeju and Seogwipo harbors during the passage of the typhoon were compared with the computed data. The simulated storm surge time series were in good agreement with the observations. The simulated peak storm surges were estimated to be 230 cm at Masan harbor, 200 cm at Yeosu harbor and Tongyoung harbor, and 75 cm at Busan harbor. The computed storm surges along the east coast of Busan measure 52 to 55 cm, exhibiting a gradual reduction in surge height as one moves further from the coast of Busan. Therefore, coastal inundation due to the storm surge in the semi-enclosed bay can induce great disasters, and the simulated results can be used as the important data to reduce the impact of a typhoon-induced coastal disaster in the future.

태풍 매미 통과 시에 부산연안에서 폭풍해일고를 해석하기 위한 수치실험을 수행하였다. 태풍 매미는 2003년 9월 12일 21:00에 중심기압 950hPa로 우리나라 남해안에 상륙하였으며, 지난 수십년 간에 걸쳐 최악의 해안재해로 기록되었다. 태풍 매미 통과시 부산항, 여수항, 통영항, 마산항, 제주항 및 서귀포항에서 관측된 폭풍해일고와 계산된 해일고의 시계열을 비교하였으며, 계산결과와 관측결과는 잘 일치하였다. 태풍해일고는 마산항에서 약 230 cm로 가장 크게 나타났으며, 여수항과 통영항에서는 약 200 cm, 부산항에서는 약 75 cm로 나타났다. 폭풍해일 수치실험결과, 부산 동부 연안에서 해일고는 52~55 cm 범위이고, 외해로 갈수록 해일고는 감소하였다. 따라서 반폐쇄된 만에서는 해일고의 상승으로 인한 연안 침수범람 피해가 크게 발생할 것으로 사료되며, 본 수치실험결과는 태풍으로 인한 연안재해 저감을 위한 중요한 자료로 사용될 수 있다.
