【摘要】 为分析厦门海域生态修复工程高集海堤开口后厦门湾的潮汐动力特征,在厦门湾重要特征位置布设6个潮位站、3个海流站,选取2016年5月的潮位及海流数据进行分析,研究现状下厦门湾的潮流特征。分析表明:高集海堤开口后,厦门湾仍为正规半日潮区,东、西海域实现贯通,东海域涨潮流延伸进入西海域,东、西海域两股潮波在高集海堤西南侧汇合,潮差从湾口向湾顶递增,在高集海堤西南侧达到最大,湾顶平均潮差为442cm。位于东、西海域口门断面潮流呈往复流,东海域最大流速为84.6cm/s,西海域最大流速为115.6cm/s。由于地形的影响,海堤开口处的潮流为旋转流性质,附近最大流速可达143.0cm/s。更多还原

【Abstract】 In order to analyze the tidal dynamic characteristics of the Xiamen Bay after the opening of Gaoji Seawall, six tidal stations and three current stations were set up at the important feature locations in the Xiamen Bay. We selected the tide level and current data in May 2016 to investigate the tidal characteristics in Xiamen Bay under the current situation.The result shows that Xiamen Bay is still a regular half-day tidal zone and the sea that was once separated by the seawall reconnected. Two tidal waves in the east and west area meet at the southwest side of the Gaoji seawall. The tidal range increased from the mouth of the bay to the top, reaching the largest on the southwest side of the Gaoji seawall, and the average tidal range at the top of the bay was 442 cm. The current in the most sea area is reciprocating flow. The max current speed at M1 station, which located in east area, was 84.6 cm/s, while 115.6 cm/s was at M2 in the west area. Due to the influence of the topography, the tidal current at the opening of the seawall is a swirling flow, and the maximum velocity was 143.0 cm/s.更多还原
