摘要
建立钱塘江河口涌潮观测体系,是防御潮灾、保护涌潮资源和研究涌潮规律的重要基础工作。在梳理以往观测资料的基础上,结合不同河段的涌潮特性和现状节点,沿钱塘江两岸布设盐官和美女坝等2站8点,按涌潮的水力特性确定涌潮高度、形态、流速、压力、行进速度、含沙量、潮位过程、河床冲淤过程及风速风向等9项观测内容,初步形成钱塘江河口的涌潮观测体系,为涌潮的保护利用及河口两岸的基础建设提供技术支撑。
The establishment of tidal bore observation system in Qiantang River estuary is an important basic work for preventing tidal disasters,protecting tidal bore resources and studying the law of tidal bore.On the basis of the previous observation data,combined with the tidal bore characteristics and current nodes of different river sections,two stations(Yanguan station and Meinǚba station)and eight points are arranged along both banks of the Qiantang River.According to the hydraulic characteristics of the tidal bore,nine observation contents are determined,such as the tidal bore height,shape,velocity,pressure,travel speed,sediment concentration,tidal level process,riverbed scouring and silting process,wind speed and wind direction.A tidal bore observation system at the Qiantang River estuary is preliminarily formed,providing technical support for the protection and utilization of tidal bore and the infrastructure construction on both sides of the estuary.
