频率组合法分析黄浦江年最高潮位频率特征

Analysis on Frequency Characteristics of Yearly Maximum Tidal Level in Huangpu River with the Combination Frequency Method

黄浦江既是一条强感潮河流,又受上游太湖流域洪水的影响。随着海平面上升,长江口、黄浦江的整治以及上游太湖流域治理工程实施等因素影响,潮位资料系列的一致性遭到了破坏,给直接采用实测资料分析潮位特征带来困难。作为一种尝试,采用频率组合的方法来分析黄浦江年最高潮位的频率特征,取得了较好的分析研究成果。

Huangpu River is a tidal river,it is also a major flood waterway of Taihu Basin.As a result of sea level rising,Yangtze Estuary and Huangpu River regulation,the flood-control projects in Taihu Basin being bring to effect,etc,the consistency of the tidal level data serial in Huangpu River is challenged,it is difficult to analyze the frequency characteristics with common method directly using tidal level measurements.In this paper,the combination frequency method is used to analyze the frequency characteristics of yearly maximum tidal level in Huangpu River,and the result is turned out to be valuable.
