摘要:
运用FVCOM模型对黄渤海的潮波系统建立了数值模拟,对海域内潮波的涨潮特征对于长江口径流量变化的响应进行了分析,用最高潮位和潮汐不对称性来量化。结果表明,黄渤海海域内最高潮位和最强潮不对称性均出现在弶港附近;潮汐不对称性在江苏沿岸海域呈现空间不均匀性,大部分海域为涨潮占优;长江口径流的季节性变化使得潮汐不对称和最高潮位都表现出不可忽略的季节性差异,洪期长江口附近水域有明显涨潮占优的发展趋势。上述研究成果可为江苏沿岸大潮位预警和潮致淹没灾害防治提供参考。
Abstract:
In this paper, a numerical platform is established by using the FVCOM model for tide simulation in the Yellow Sea and Bohai Sea. The response characteristics of the flood-tide, indicated by the peak-water-level and tidal asymmetry index, to the variability of the Yangtze River discharge are analyzed. Results showed that the peak-water-level (~3.5 m) and the strongest tidal asymmetry are both near the Jianggang Port in this region. The tidal asymmetry shows spatial heterogeneity in the coastal waters of Jiangsu province, and is flood-dominant in most area. The seasonal variation of the Yangtze River discharge flow leads to nonnegligible seasonal variation in the tidal asymmetry and the peak-water-level over the domain. Tendency to flood-dominance near the Yangtze River estuary is prominent during flood seasons. The results of this study can provide theoretical support for improving early warning system of high-tides, and prevention management of tide-induced inundation hazard along Jiangsu coast.
