摘要
以海棠湾规划水系工程为背景,建立了水动力及水体交换二维数学模型,通过模拟示踪剂的浓度变化计算了不同工况下的水体交换率,评价了复杂水系内部的水体交换能力。结果表明:连续潮作用30 d后海棠湾水系整体水体交换率均在69%左右,不同区域水体交换能力分布不均,其中藤桥最佳,铁炉港外港其次,内河水系再次,铁炉港内港最差。
Taking a planning water system project in Haitang Bay as background, a 2-D numerical model for tidal current and temperature diffusion was set up. Using the method of dissolved tracer variation, the water exchange rate of the Haitang Bay, China was simulated. Then the water exchange ability of the interior water system was evaluated. Research results show that: the monthly water exchange rate of the whole water system of Haitang Bay is about 69%. Different sections show nonuniform distribution, where Tengqiao is the best, Tielu outer port is the second, the internal waterway is the third, and Tielu inner port is the worst.
