초록
2013년부터 2017년까지 5년간 우리나라 동해안에서 발생한 너울에 의한 사고 사례를 수집하였다. 사고발 생역, 발생계절, 발생해안종류, 피해대상별로 분류하고, 사고 당시의 인근지역 파랑관측자료를 수집하여 사고와 파 랑자료와의 상관성을 분석하였다. 또한 국립해양조사원의 연안재해취약성 평가 결과에 기반하여 너울 사고 발생지 점의 취약성 등급을 분석하였다. 너울 사고지역은 파랑노출지수의 평균등급이 4.91, 파랑민감도지수는 3.87, 종합평 가결과인 파랑영향지수는 4.90으로 높게 나타났다. 이에 대부분 너울 사고가 파랑영향지수 5등급에서 발생한 것에 기인하여 동일 등급으로 평가된 동해안 지역(78.7%)을 대상으로 파랑민감도지수와 연계하여 지역을 분류하고 각 지 역의 특성에 맞는 대응방안을 마련하였다.
Abstract
In this study, we collected cases of accidents caused by swell in the east coast of Korea from 2013 to 2017. The location of the accident, the season, the type of coast and the type of damage were classified and the correlation between the accident and the wave data was analyzed by collecting the observation data of the nearby area at the time of the accident. Also, based on the results of the coastal disaster vulnerability assessment of Korea Hydrographic and Oceanographic Agency, the vulnerability grades of swell accidents area were evaluated. In swell accident area, the average grade of the wave exposure index was 4.91, the wave sensitivity index was 3.87, and the wave impact index was 4.90. As a result, most of the swell accidents occurred in the 5 grade (very vulnerable level) of the wave impact index, and the area of the east coast (78.7%) of the same 5 grade was classified into five types according to the wave sensitivity index result. Finally, a countermeasures was taken for characteristics of each type.
