跨流域调水工程通常被认为是通过将过剩地区的水资源调到贫乏地区来平衡水资源和水资源需求时空分布不均的最有效设施之一。然而，这些项目的运作总是令人望而生畏，特别是对于拥有多个捐赠者储藏库但只有一个接受者储存库的项目。在这项研究中，首先提出了一套输水规律曲线，以确定何时、何地和多少水应该从每个供给者水库引水。此外，还建立了以缺水风险和脆弱性最小为目标的模拟优化模型，得到了最优调度规则曲线。在此基础上，应用新的调水规则，为中国中部两座供水库调水工程的运行提供了指导意见。在不调水、从供水库引水和从两个供水库引水等不同情况下，对各水库的调水效果进行了评估。结果表明，该方法对改善整个引水系统的运行性能具有一定的优势，证明了该方法的可行性。
Inter-basin water transfer projects are usually considered as one of the most effective facilities to balance the non-uniform temporal and spatial distribution of water resources and water demands by diverting water from surplus to deficient area. However, the operation of these projects are always daunting, especially for projects with multi-donor reservoirs but only one recipient reservoir. In this study, a set of water transfer rule curves are firstly proposed to determine when, where and how much water should be diverted from each donor reservoir. In addition, a simulation-optimization model with the objective to minimize both water shortage risk and vulnerability is established to derive the optimal operation rule curves. Following that, the new transfer rules are applied to provide guidelines for the operation of a water transfer-supply project with two donor reservoirs in central China. The effects of water diversion on each reservoir are evaluated under different scenarios including no diversion, diversion from the donor reservoir with relatively sufficient water, diversion from the donor reservoir with relatively limited water, and diversion from both donor reservoirs. The results show the advantages of improving the performance of whole water diversion system and demonstrate the feasibility of the proposed approach.
