초록

본 연구에서는 천 등(2009)의 동적결합형 POM-WAM 모형을 천해역 해빈류 현상 중 하나인 해향저류(undertow) 문제에 적용하였다. 수치모형의 해향저류 계산 결과를 향상시키기 위해 surface roller에 대한 방정식을 풀고, 이를 해향저류 계산에 포함시켰다. 수치모형을 Okayasu and Katayama(1992) 및 Cox and Kobayashi(1997)의 수리모형 실험에 적용하고, 계산 결과를 수리모형 실험 결과 및 Tajima and Madsen(2006)의 수치계산 결과와 함께 비교하였다. 그 결과, 본 수치모형의 계산결과와 실험결과가 잘 일치하는 것으로 나타났다. 이를 통해, 본 수치모형이 쇄파대를 포함한 천해역에 적용 가능함을 확인하였다.

Abstract

In the present study, the dynamically coupled POM-WAM of Chun et al.(2009) was applied to the numerical simulation of undertow, one of the nearshore currents. To improve the accuracy of the numerical model results in surf zone, the transport equation of the surface roller was solved, and its effects were incorporated into the present numerical model. The numerical model has been applied to two hydraulic experiments of Okayasu and Katayama(1992) and Cox and Kobayashi(1997). The numerical results were compared with the hydraulic experimental results to give a good concurrence. It is concluded that the present numerical model can be applied to the shallow water region including surf zone.
