At present, there are ten major rivers in Hangzhou, which are managed by municipal departments, namely Xinkai River, Tiesha River, Donghe River, Zhonghe River, Guxin River, Guanhe River, Nanyingjia River, Yanshan River, Xixi River and Tang Yuhang River. Xinkai River starts from Shuangyangmen and flows northeast to the west gate of Dinghai, with a length of 4,372 meters and a river width of 8 to 10 meters. At the west gate of Dinghai, there is an agricultural irrigation canal flowing southeast, which is connected with Qiantang River at Jianggan Pumping Station. Tiesha River now starts from Zhongmeimen (connected by a culvert and the middle river) in the south and ends at Genshanmen in the north, with a total length of about 6 100 meters and a water surface width of 15 to 70 meters. This river is the water conveyance channel and fresh water reservoir of Qingtai Waterworks of Hangzhou Water Supply Company. Donghe River and Zhonghe River were comprehensively regulated in 1980s, and now they are the best secondary rivers in urban areas. Guxin River is the main drainage channel of West Lake. It starts from Tangshengmen in the northeast of West Lake, flows northward to Zuojiaqiao, bends eastward and joins the Beijing-Hangzhou Canal, with a total length of 3,800 meters. Guanhe River is 650 meters long and 4 to 8 meters wide, from railway kindergarten to Tanhemen. Nanyingjia River is located in the residential area of Zhao Hui, starting from Shangtang River in the east and reaching the canal in the west, with a total length of 1300m. Surrounded by mountains and waters, it originated at the northern foot of Ban Zhao in Yuhang, connected with the Beijing-Hangzhou Canal along Liu Liu Town and Tianmushan Road, and reached Baziqiao and Xixi River in the urban area. The present urban area along the mountains and rivers refers to the section from Gudangwan to Baziqiao, with a total length of about 2,500 meters. Xixi River is an extension along the mountains and rivers. Now Xixi River refers to the reach from Baziqiao to Yuhang Tanghe River. Yuhang Tanghe River belongs to the urban management scope, from Hangzhou Sulfuric Acid Factory to Guanyin Bridge, with a total length of1740m. The width of riverbed varies from 22m to15m. Historically, the Longshan River was originally a waterway from the middle reaches to the Qiantang River. Longshan River now starts from the sluice in the south and ends at Fengshanmen in the north, connecting the middle reaches, with a total length of 4,400 meters, and is no longer connected with Qiantang River. The water source comes from the cooling water of sluice power plant. With the reconstruction of the south section of Zhonghe River, a two-way water pump station is being built from Zhakou to Baitaling to reconnect with Qiantang River. In the urban area of Hangzhou, especially in the urban-rural fringe, there are many rivers, such as Shangtang River, Beitang River, Xitang River, Xinhenghe River, Shengli River and the water intake river of Hangzhou Steel. Because most of these rivers play the role of farmland irrigation and drainage, they are agricultural irrigation rivers managed by forestry water administrative departments, and now they are not included in the scope of urban municipal river management.
