Abstract

This study investigates the characteristics of stem waves along a vertical wall generated by obliquely incident random waves through laboratory experiments conducted in a wave basin and numerical simulations using REF/DIF S model developed by Kirby and $\ddot{O}zkan$(1994). The investigation is focused on the effect of random waves on the propagation characteristics of stem waves and the difference or similarity between monochromatic and random waves. The results of REF/DIF S model are compared with laboratory measurements and good agreements are obtained. The relative significant wave height along a wall is almost same with monochromatic condition, but the wave pattern along normal to the wall shows a significant difference.

본 연구에서는 직립벽을 따른 불규칙파의 연파특성을 평면수조를 이용한 수리모형실험과 Kirby and Ozkan(1994)에 의해 개발된 REF/DIF S 모형을 이용한 해석결과를 통해 검토하였다. 본 연구에서는 불규칙파에 의한 연파특성, 규칙파 및 불규칙파에 의한 차이점과 유사점을 검토하였다. REF/DIF S모형에 의한 불규칙파의 연파 해석결과는 수리실험결과와 잘 일치하였다. 제체 전면을 따른 상대파고는 규칙파 및 불규칙파 모두 유사하게 나타났으나, 제체 직각방향의 파고분포 경향은 매우 큰 차이를 보였다.
