长江口北支咸潮倒灌控制工程水动力数值模拟

Hydrodynamic simulation of control project on saltwater intrusion from north branch of Yangtze River Estuary

运用水流数学模型对长江口北支咸潮倒灌控制工程方案进行模拟,分析了3个控制工程方案实施后的效果及对周边区域的影响。结果表明,综合咸潮倒灌的控制效果、防洪排涝影响及对南支的影响等,中束窄方案为本研究的推荐方案。

The schemes for the control project on saltwater instruction were simulated by use of the hydraulic model, and the effects of three schemes implemented in the control project and their impacts on surrounding regions were analyzed. By comprehensive analysis of the control effects on saltwater intrusion and their impacts on flood control and drainage as well as influence on the south branch of the Yangtze River Estuary, the mediate narrowing scheme was recommended.
