초록

동해안 남항진 해변에서 1.6 km 떨어진 수심 30.5 m 해역에서 초음파식 파고 파향계를 이용하여 2013년 2월부터 2018년 11월까지 연속 관측을 실시하여 취득된 파랑자료를 분석하였다. 파별분석법과 스펙트럼법에 의해 파고와 주기를 분석하고 두 방법에 의해 산정되는 파라메터 사이의 관계식을 선형 회귀분석에 의해 도출하였다. 또한 유의파고, 유의파주기, 첨두파향의 월별 및 연별 변동성을 분석하였다. 이에 더하여 유의파고와 유의파주기의 상관관계식을 새롭게 제시하고 유의파고에 대한 유의파주기의 변동성 및 확률분포 특성을 고찰하였다.

This study presents the results of analysis for the wave data that were consecutively collected from February 2013 to November 2018 at the location of 1.6 km offshore from Namhangjin beach. The water depth at the location is 30.5 m and waves were measured by AWAC (Acoustic Wave And Current meter). By using wave-by-wave analysis and spectral analysis, wave heights and periods were evaluated and then the relationships between the quantities obtained by the two methods were proposed based on linear regression analysis. In addition, monthly and yearly variations of the significant wave height and period, and the peak wave direction were analyzed. Moreover, the relationship between the significant wave height and period was newly suggested. Variability and probability distribution of the significant wave period with respect to the significant wave height were also examined.
