渤海局部海域风暴潮漫滩的数值模拟
史峰岩, 孙文心
青岛海洋大学物理海洋研究所 青岛 266003
摘要:
在Johns变边界模型的基础上,提出了一种嵌套式变边界数值模型,应用于渤海风暴潮的数值计算。分别模拟得到了1964年和1969年两次渤海风暴潮黄河三角洲一带的最大淹水范围和水位过程曲线。模拟过程中考虑了天文潮与风暴潮的非线性耦合效应。模拟结果分别与实测值和固定边界模型的结果进行了比较,从而证实了变边界模型不仅能计算出最大淹水范围,而且得到的风暴潮水位值也更加符合实际。

NUMERICAL SIMULATIONS OF THE INUNDATIONS OF STORM SURGES IN PARTIAL AREAS OF THE BOHAI SEA

Abstract:
This variable boundary model developed from a fixed boundary model can be used to simulate astronomic tides and storm surges in inshore coastal areas and is effective for accurate prediction of disasters in the Bohai Sea. The predicted inundated areas and surge elevations in the Huanghe River Delta were obtained in the simulations of storm surges in 1964 and 1969. In the two simulations, the non-linear interaction between tide and surge was considered. The Simulations showed that the variable boundary model can be used to get not only predicted inundated areas but also surge elevations closer to the observed elevations.
Key words:  Storm surge, Inundation, Variable boundary model
