大型浅水水库防洪、供水、保护生态环境，是社会发展的重要功能。苏鸭湖水库作为中国境内最大的人工平原水库，近年来泥沙淤积严重，水质恶化。建立了基于环境流体动力学程序(EFDC)的三维水动力和水质模型。模型被应用于7个情景，以评估水库水动力和水质对修复措施的响应，包括扩建和疏浚工程、外部减负和来水调节。结果表明：(1)扩容清沙工程对水库水质没有明显改善；(2)外减载能显著改善水库水质；(3)汝河两个进水口流量分布均匀，水动力和水质改善最好时，出现最优来水条件。此外，不断增加的水交换率并不能带来同样的水质改善，这表明用单一指标评估恢复措施的效果可能是不可靠的。该研究可为大型浅水水库制定和实施有效的修复措施提供有用的信息。
Large shallow reservoirs control flooding, supply water, and protect the ecological environment, which are vital functions for societal development. As the largest artificial plain reservoir in China, Suyahu Reservoir is suffering from significant sedimentation and water quality deterioration in recent years. A three-dimensional (3-D) hydrodynamic and water quality model was developed based on the Environmental Fluid Dynamic Code (EFDC). The model was applied to seven scenarios for evaluating the response of in-reservoir hydrodynamics and water quality to the restoration measures, including expansion and sediment dredging project, external load reduction, and inflow regulation. The results show that: (1) the expansion and sediment dredging project has no notable improvement on the water quality of the reservoir; (2) the external load reduction can significantly improve the water quality of the reservoir; and (3) the optimal inflow condition occurred when the flows of Ru River’s two inlets were evenly distributed, and the hydrodynamics and water quality were best improved. Moreover, the increasing water exchange rate could not cause the same water quality improvement, showing that it may be unreliable to evaluate the effects of restoration measures using a single indicator. This study can provide useful information for developing and implementing effective restoration measures in large shallow reservoirs.
