摘要: 文中利用水龄浓度概念, 结合计算水交换时间的水质模型公式, 在EFDC(环境流体动力学模型)水动力基础上, 分别计算了1965年和2006年清澜潮汐汊道的海湾水交换时间。研究结果表明, 2006 年的平均水交换时间为107d, 1965 年的平均水交换时间为114d, 发生变化的主要原因是清澜港航道被浚深至7~8m, 潮汐动力显著增强, 纳潮量增加了4.3%所致。

Abstract: Based on the hydrodynamic model of the environmental fluid dynamics code (EFDC), The water exchange in the Qinglan tidal inlet was calculated in 1965 and 2006 using water age concentration and water quality formula. The results showed that the average water exchange time of the Qinglan tidal inlet was about 107 d in 2006, while it was about 114 d in 1965. This was mainly because the Qinglan harbor channel was dredged to 7~8m, which led to significantly enhanced tidal energy and the increase of tidal prism by 4.3%.
