Main tributaries of Yongjiang River
Liangfeng River is also known as Nali River and Shuitang River. In ancient times, it was called Hujiang River and Wushui River. In ancient times, it was called Heshui River and Wushui River. The river has two sources: one originates from the southern foothills of the high mountains at the junction of Yongfu in the north of Suwei Town and the stone mountain group west of Rende in Suwei. The water is stored in Tanpeng, Liusi, Lutao and other reservoirs, and then converges at Dingying Village. The nearby area is called Paihuan River; the first one originates from the eastern foot of Fusui Gonggao Mountain and is called Paile River. It flows into Tiantang Reservoir and reaches the northwest of Maocun where it merges with Paihuan River. After the two sources merged, it was called Liangfengjiang River. The Liangfeng River receives water from Wuwei, flows from Xiaonadan to the suburbs of Nanning, then enters the county and becomes the boundary river between the suburbs and counties, and flows into the Yongjiang River at the mouth of the reservoir. Liangfeng River flows through Suwei and Wuwei, with a basin area of 536.2 square kilometers, an average annual flow of 6.8 cubic meters/second, a river curve length of 65.33 kilometers, a width of 20 to 30 meters, a water surface area of 0.8 square kilometers, and a natural drop of 305.9 meters.
Bachijiang River is the largest tributary of Yongjiang River in the county. The river has three sources: Fengting River in the main source, Nanzhou River in the east, and Pingjiang River in the west. Fengting River, also known as Shanzidong River, originates from the northern foot of Leimaoling in Shangsi County. After flowing into the county, the river was dammed and the Fengting River Reservoir was built. The Nanzhou River originates from the northern foot of Jianjian Mountain and has four river sources. The West River source comes from Jicai, Shangsi County, and the rest come from the county. In 1958, dams were built at 4 rivers in Peicha, Hengqi, Hengdou, and Tunliu. Starting from the east main channel of Fengting River Reservoir, it connects with Guaku Group and Tunliu Reservoir. The flowing water from these two reservoirs reaches Datang Kangli and merges into the Talc River. The Talc River then receives small water from Nali and Naxing 2, and flows to Gong'an and Fengli Rivers. The Tinghe River merges with Dawangtan Reservoir and then merges with Xinjiang River at Liangqing Xinlan. It then merges with other small rivers along the way and flows into the Yongjiang River at the edge of Pumiaozhai Shang Village.
Xinjiang River, formerly known as Nayue River and Renli River, is the largest tributary of Bachijiang River and a third-level tributary of Yongjiang River. Its main sources are Xinjiang River, Naweng River and Siling River. 1. The Xinjiang River has three main sources. The main source comes from Zhenlong Maoling Reservoir and Tunliang and Nata. The west source comes from Naxu and Tunlu in Baekje. The east source comes from Naloutandun. They converge successively near Sanjiang. The flow rate is 0.32 cubic meters/second, and reaches the Nanawong River near Tuanyang, then to the Nasling River in Nayue, Pumiao, and flows into the Bachi River in Xinlan, Liangqing. 2. Naweng River, also known as Yingli River, has three sources. The main source gathers the small waters of Baekje, Tuncha and Nanxiaotuancheng, and the west source gathers the small waters of Datang Napu, Nabu and Nanrong. With the flowing water of Baekje Wenbi Reservoir, Zhengyuan and Xiyuan merge with Baekje Yingli, Dongyuan merges with Baekje and Namhwa, and ends at Xinjiang Hualien where it joins Zhengyuan and Xiyuan, and then the hero reservoir is built upstream. Two small streams of water flow into Xinjiang River near Xinjiang Natao. 3. Siling River is also called Siling River. One source originates from the eastern foot of Chendingzhi Mountains, and the other originates from Datang Garden Slope. After the two sources merge with Chenbaipai, the river is 10 to 30 meters wide and 1.5 meters deep. ~3 meters, and then reaches Liangqingna Mountain to join the Xinjiang River. The Xinjiang River flows into the Bachi River near Liangqing Xinlan. The main source of the Qinglong River comes from Nalou Tunliu. When it reaches Nalou, Tenma built the Nalin Reservoir to collect water along the way. When it reaches Liuwei, it builds a Qinglongjiang Reservoir near Nabu. It flows into the Yongjiang River at Changtang Zhongdou; in the east The source collects the Liuwei Najiu, Najiu, Luyang, and Huaili waters, and reaches the Ma'an Reservoir built near Tuanhuang, and then flows into the Qinglong River Reservoir. The Qinglong River flows through Nalou, Liuwei, and Changtang, with a basin area of 218 square kilometers, an average annual flow of 2.87 cubic meters/second, a river length of 30 kilometers, a width of 10 to 15 meters, and a depth of 3 to 5 meters. are all hilly and plain areas. The source and flow of Santang River are both north of Santang on the outskirts of Nanning City. Its downstream enters Najiu Village, Changtang Township, and flows into the Yongjiang River at the mouth of the Scissor River. The Sitang River, also known as the Shileng River, has two main sources, both originating in Wuming County. After converging, it flows into the county from the Yanhe branch of the Gaofeng Forestry Farm, flowing from north to south, passing through Nabi and Sitang, and finally to Xinxinzhuan. It flows eastward and joins the Shajiang River near Baogai. The Xiyuan comes from the western foot of Dingxiang Mountain, passes through Tongren, and then goes downhill to join the Zhengyuan. Sitang River only flows through Sitang Township, with a length of 50.45 kilometers, a drainage area of 171.1 square kilometers, a width of 50 to 100 meters, a depth of 3 to 5 meters, an annual average flow of 2.96 cubic meters/second, and a natural drop of 54.8 meters. Shajiang River, also known as Dachongjiang River, is a secondary tributary of Yongjiang River and the second largest tributary in the county. The main source is the Batang River, and the six larger tributaries (including the Sitang River) all meet from north to south.
The Batang River has three sources, the east source comes from the western foot of Paixian Mountain, the middle source comes from Jiutang Guxi and Gudi and converges at Jiutang, the west source comes from Baizuo Mountain and converges at Nahui in the east, and the three sources in the east, middle and west converge at Badang River. After the pond, it is called Batang River, and after Batang River enters Wutang territory, it is called Shajiang River. The Shajiang River flows from east to west, passing through Wangzhu, Liangshan, and Youai, and then reaches Hejiang and enters Sitang Township. It then turns south and receives water from the Sitang River near Baogai, enters Changtang Township, and flows into Yong near the mouth of the Dachong River. River.
The Lingjiang River, also known as the Lingli River and the Tuojiang River, originates from the Gaotianwei area in Binyang County. It goes to Nazhang where it receives water from Jiutang, and then near Xiawang where it receives water from Madu and Huangling. It flows through the Tuojiang River and flows into the Yongjiang River at the edge of Lingliwei. The Lingjiang River flows through Jiutang and Lingli in the county. It used to be an important road for the exile of bamboo trees. The county has a drainage area of 256.3 square kilometers and an average annual flow of 5.2 cubic meters/second. The river section in the county is 53.97 kilometers long and the river width is 15 to 20 kilometers. meters, with a depth of 3 to 5 meters, a water surface area of 0.81 square kilometers, and a natural drop of 781.8 meters.
