초록

최근 빈번하게 발생하는 해상 유류사고에 대해 초기에 신속히 대응하기 위해서는 정확성 높은 수치해석 모형의 개발 및 적용이 필수적이다. 본 연구에서는 불규칙한 지형적 변화가 존재하는 근해역에서 유출유의 정확한 확산예측을 위하여 비선형성, 분산성, 난류 및 회전류 효과 등이 포함된 수심적분형 Boussinesq 모형과 유류의 이송-확산-변형모형을 통합함으로써 유출유 초기확산 예측을 위한 결합모형을 개발하였다. 개발된 모형은 지형적 복잡성 및 그에 따른 실제 흐름의 특성을 지닌 실 해역에 적용함으로써 모형의 활용성을 검토하였다. 고해상도의 해상 조건 재현이 가능한 본 개발모형은 기후변화 등에 의해 점차 강화되는 해상 기상의 극한조건에서의 유류 재해에 대비할 수 있는 방재시스템 구축에 도움이 될 것으로 기대된다.

The development and application of accurate numerical models is essential to promptly respond to early stage of oil spill incidents occurring in nearshore area. In this study, the coupled modelling system was developed by integrating the advection-diffusion-transformation model for oil slick with the Boussinesq model, which incorporates non-linear, discrete, turbulent and rotational effects of wavy flows for accurate representation of nearshore hydrodynamics. The developed model examined its applicability through the application into real coastal region with topographical complexity and characteristics of the resulting flow originated from it. The highly-resolved, coupled model developed in this study is believed to assist in establishing the disaster prevention system that can prepare effectively for oil disasters under extreme ocean climate conditions and thus minimize industrial, economical, and environmental damages.
