The pursuit of flood prevention safety and the mitigation of drainage contradiction against an unnecessary influx of floodwater require a modern and efficient model to optimize the management of the initial allocation of flood drainage rights. We attempted to formulate a framework for initial flood drainage rights allocation to promote the sustainable drainage of the Sunan Canal, China. The Pressure-State-Response (PSR) model was constructed using a literature review and interviews with experts and directors using 18 key indicators being determined from field surveys and library studies. We then assessed the flood status of Zhenjiang City, Changzhou City, Wuxi City and Suzhou City in the Sunan Canal zone using an entropy-based matter-element model. The flood drainage rights for a total of 400m3/s was allocated to the four cities in accordance with their flood status. Our research demonstrated that, overall, the four cities may gain the flood drainage rights of 106.67m3/s,120.40m3/s, 118.22m3/s and 54.71m3/s, respectively. Specifically, the calculation of the flood drainage for Wuxi was very close to the actual allocation in 2016, whereas there were differences in the other cities that should not be neglected.
追求防洪安全和缓解排水矛盾，防止不必要的洪水涌入，需要一个现代高效的模型来优化洪水排水权初始分配的管理。我们试图制定一个初始洪水排水权分配框架，以促进中国苏南运河的可持续排水。利用文献综述和对专家和主任的访谈，使用从实地调查和图书馆研究中确定的 18 个关键指标，构建了压力-状态-响应（PSR）模型。然后，我们使用基于熵的物元模型评估了苏南运河地区的镇江、常州、无锡和苏州四个城市的洪水状况。根据洪水状况，为这四个城市分配了总计 400m3/s 的洪水排水权。我们的研究表明，总的来说，四个城市可能分别获得 106.67m3/s、120.40m3/s、118.22m3/s 和 54.71m3/s 的洪水排水权。具体来说，无锡的洪水排水计算非常接近 2016 年的实际分配情况，而其他城市的计算结果存在差异，不容忽视。
