摘要
利用瓯江河口及东部近岸海区11个验潮站的实测大潮和小潮潮位过程进行统计,并探讨了潮波由外海向瓯江河口及上游传播过程中潮差的沿程变化。结果表明,受水下地形摩阻、岛屿阻隔及岸线束窄作用,潮波由外海向河口内传播过程中,潮差逐渐减小,且低潮位逐渐抬高;同时,越靠近河口及上游,潮差沿程变化越为显著。
Tidal feature of estuary region is very important for the design and construction of port and wharf engineering.This paper makes use of the statistics of measured spring tide and neap tide level process of the Oujiang estuary and 11 tide stations located in the eastern coastal area, and discussed the change of tidal range during the process of tidal wave propagation from the coast to the Oujiang estuary and the upstream. Results show that by the effect of the underwater topographical friction, island blocks and coastline contraction, in the process of tidal wave propagation from the coast to the estuary, the tidal range decreases, and low tide gradually elevates.Meanwhile ,the closer to the estuary and the upstream ,the more obvious the tidal range becomes.
