With a total length of 1.794 km, the Beijing-Hangzhou Grand Canal is the longest artificial canal in the world, which is 1.6 times that of Suez Canal and 33 times that of Panama Canal. It runs through the north and south and is an important north-south water trunk line in China. It carries a lot of materials between the North and the South, and also contributes to the political, economic and cultural development of China. Due to disrepair, the current navigation mileage of the Beijing-Hangzhou Canal is 1442 km, starting from Beijing to Hangzhou in the south, passing through six provinces and cities including Beijing, Tianjin, Hebei, Shandong, Jiangsu and Zhejiang, and connecting five major water systems: Haihe River, Yellow River, Huaihe River, Yangtze River and Qiantang River. Not only is it beneficial to the annual navigation mileage of 877 kilometers, mainly distributed in Shandong, Jiangsu and Zhejiang provinces south of the Yellow River,
