| 摘 要： | 运用ECOMSED建立了长江口的水动力模型。潮位和流速的验证结果表明模型能够较好地反应长江口的水动力特性,可以应用于长江口的实际计算。对2010年7月长江发生的大洪水对长江口的水动力特性的影响进行了模拟。模型计算结果表明,由于三峡工程的蓄水作用,使得长江口附近的流速发生明显的减小,对污水的稀释扩散和水环境也会产生一定的影响。上海三个排污口分别排出稀释度为1000的污水时,由于三峡工程的蓄水,上游来水量相应减少,不利于上海排出污水的稀释扩散。

| Abstract: | In this paper,the hydrodynamics of Yangtze River Estuary was modeled based on ECOMSED.Results show that the model reveals the characteristics of hydrodynamics of the estuary well and can be applied to realism.A simulation was conducted to a flood in July 2010 for illuminating how it affects the hydrodynamic characteristics of Yangtze River estuary.The results showed that the impoundment of Three Gorges Project leads to a significant decreasing of flow rate around Yangtze River Estuary,which in turn affects ... |
