Abstract：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.
