Abstract：This study examines the evolution of the confluence points of the East Tiaoxi River and the West Tiaoxi River in the Tiaoxi River system,located in the upstream region of the Taihu Lake Basin.The confluence points in Huzhou City,Zhejiang Province,have undergone four changes throughout history.The convergence initially occurred east of the main city at"Sanli Bridge"from around 3000 BC to about 200 AD,then shifted to the area within the main city known as"Jiangzhuhui"around 400 to 1800 AD.After 1958,the confluence point moved west of the main city to"Hangchang Bridge",and after 1993,it shifted north of the main city to"Baiquetang Bridge".Given the historical connection between the Tiaoxi River basin and the Qiantang River basin,learning from international cases of"flood tunnel integration",by diverting mountain floodwater directly into the Qiantang River through tunnels originating from the Qingshan Reservoir in the upstream region of the East Tiaoxi River,we aim to provide a solution for the high-quality integrated development of the Yangtze River Delta,as well as contribute to the construction of happy rivers and lakes and the development of ecological civilization.
