摘　　要：数字孪生流域是推动智慧水利建设的核心和关键,而水利专业模型是数字孪生流域建设的重要算法支撑。从实际业务支撑角度研发面向防洪“四预”的数字孪生流域水利专业模型,包括水文、水动力、水工程调度、风暴潮等模型,并以浙江省温州市的数字孪生飞云江流域为载体进行实践应用。结果显示,在应对台风“杜苏芮”“卡努”“鸿雁”过程中,各类模型运行情况良好,水文、水动力及风暴潮模型预报值与实测值拟合程度较高,误差满足规范许可要求,水工程调度模型可实现模型预期调度效果。研发的水利专业模型和应用案例可为其他流域数字孪生建设提供参考。Digital twin watershed is the core and key to promoting smart water management,and water resources professional models are crucial algorithmic support for digital twin watershed construction.From the perspective of practical business support,this study focuses on the development of a digital twin watershed water resources professional model for flood control“four pres”,including hydrological,hydraulic,water projects operation,and storm surge models.The application is demonstrated using the digital twin Feiyun River basin in Wenzhou City,Zhejiang Province.The results show that the models performed well during the response to typhoons such as“Doksuri”,“Khanun”and“Kirogi”,with a high degree of fitting between predicted and actual values,meeting the required error standards.The water projects operation model achieved the expected results.The developed professional model and application case can provide references for the construction of other digital twin watersheds.
