钱塘江澉浦站和盐官站高潮位相关性研究

Correlation Research on High Tide Levels at Ganpu and Yanguan

钱塘江嘉兴段是强涌潮段,潮位的高低影响着海塘的安全。目前,嘉兴段的天文潮预报只有乍浦站和澉浦站,缺少盐官站,根据对澉浦站与盐官站历年的实际潮位资料分析,得出其相关性,通过澉浦站预报的天文潮来预报盐官天文潮,对于管理部门在海塘管理和防台防汛工作中有实际意义。

Jiaxing Section of the Qiantang River is a section with strong tidal bore,whose tide level will affect the safety of the seawalls.There are currently only two stations for the astronomical tide forecast of the Jiaxing Section at Zhapu and Ganpu,but not at Yanguan.Based on the data analysis of actual tide levels at Ganpu Station and Yanguan Station over the years,the correlation between them is obtained.Forecasting the astronomical tide at Yanguan from the forecast at Ganpu Station is of practical significance for the administrative departments in seawall management and flood control.
