"Diverting the Wen River to the Canal" is an important water conservancy project of the Grand Canal since the Yuan Dynasty, and its development and evolution are quite typical among water conservancy projects in the Shandong section of the Grand Canal. Based on the historical inheritance of the ancient Wen waterway, the precise understanding of the location of the Shandong ridge and the correct choice of the gate dam and the channel, Daicun Dam and Xiaowen River have become the key projects of diverting the Wen River to the Canal, ensuring the smooth navigation of water transportation for hundreds of years. In the late Qing Dynasty, the migration of the Yellow River to the North stopped the canal, and the Wenshui River no longer flowed into the canal. As a result, Xiaowen River and Daicun Dam became flood control and flood discharge projects in the lower reaches of Wen River. The decline of water transportation, the intensification of water disputes and the threat of flooding gradually weaken diverting the Wen River to the Canal. This paper, by analyzing the evolution of the water conservancy project of diverting the Wen River to the Canal, can not only reflect the evolution of the water source project in the Shandong section of the Beijing-Hangzhou Grand Canal and the relative uniqueness of the role of some water conservancy projects, but also probe into the deep correlation between the canal project and the transportation policy with shared fate.
