Abstract

An approach for producing a rip current risk index using the rip current likelihood distribution obtained through the FUNWAVE simulations was applied to a rip current forecast system. The approach originally developed for an observation-based real-time rip current warning system was utilized with wave forecast data instead of observations for the rip current forecast system. The availability of the present approach was checked by comparing the observation-based rip current risk index and the wave forecast-based rip current risk index of the Haeundae Beach in 2021.

FUNWAVE 이안류 수치모의를 통해 얻은 이안류 발생정도 분포(파고-주기, 파고-조위, 파고-파향, 파고-주파수 스펙트럼 광협도, 파고-파향 스펙트럼 광협도)를 이용한 이안류 위험지수 생산 기법을 이안류 예보체계에 적용하였다. 이 기법은 관측 기반의 실시간 이안류 경보체계를 위해 개발되었으나, 관측정보를 대신하여 파랑예보 정보를 사용하므로 예보체계에 활용하였다. 2021년 해운대 해수욕장에 대하여 관측 기반으로 생산된 이안류 위험지수와 파랑예보 기반의 지수를 비교하여 그 가능성을 검토하였다.
