초록

국내 서해안과 남해안의 조위자료로부터 조석-해일 비선형효과에 대한 발생실태를 조사한 결과 부산을 제외한 모든 해역에서 비선형성이 확인되고 있으며 특히 목포 및 완도를 중심으로 한 서남해안에서 두드러지게 나타나고 있다. 대규모 해일이 드물기 때문에 창조집중에 대한 사례는 흔치 않은 반면 저조시 조위편차가 커지는 조석변조해일은 빈번하게 발생하고 있다. 또한 낙조우세가 심한 목포해역의 경우 새로운 형태의 조석-해일 비선형성에 의해 낙조시 해일고가 크게 나타나는 현상을 확인하였다. 조위편차 산정과정에서 비선형성과 관련된 오류를 해소하는 방안으로 편기해일고 산정방법에 대해서도 검토하였다.

Hourly tide-gauge data at 10 tide stations along the West/South coasts were analysed statistically for tidesurge interaction. Interactions were found at all stations except Busan, prominently at the western tip of the South coast near Mokpo and Wando. A well-known interaction pattern which occurs at flood tide was found rarely at domestic coasts, while another pattern of the tide-modulated surge which occurs at low tide was detected frequently. In addition, a new interaction pattern which occurs at ebb tide is discovered. This pattern is found at Mokpo where the ebb dominance is prominent. Finally, the skew surge could be considered as a tool coping with such interactions.
