초록

최근 우리나라 동해안에는 너울성 고파의 반복적인 내습이 빈발하고 있다. 외해에서 발생하여 갑작스런 내습과 함께 인명과 시설에 피해를 끼치는 너울성 고파를 대상으로 그 처오름 특성을 확인하였다. 파랑 스펙트럼의 형상을 정량화하기 위해 스펙트럼 형상모수 $Q_p$, ${\varepsilon}$, ${\nu}$ 등을 도입하여 이들 모수들과 유의파고 및 첨두주기와의 상관관계를 파악하였고, MIKE21 BW 모듈을 사용하여 완경사 해안에 대한 처오름 수치실험을 수행하였다. 파고와의 상관관계가 가장 낮은 $Q_p$를 추가적인 형상 변수로 채택하여 파랑 스펙트럼의 형상 변화에 따른 처오름 높이의 변화와 특성을 확인하였다.

Recently the large-height swell-like waves generated in the eastern coast of South Korea have been observed frequently. The characteristics of the runup and overtopping of the large-height swell-like waves formed in deep water and attack the coast, causing damages to both lives and facilities have been studied. The correlation between spectral shape parameters and significant wave height has been investigated by analyzing long term wave spectrum data. Numerical runup experiments using MIKE21 BW Module were performed with $Q_p$, additional shape parameter, and identified the variations and characteristics of runup heights with respect to the variations of spectral shape.
