Saring River (Saren River) originated from Huamugou National Forest Park in Wulan, Hongshanzi Township, Chifeng City, Inner Mongolia Autonomous Region. A number of mountain streams converge, and then flow from south to north to Shengyuan, where they join the Shali Mohe River (source water) and the Xilamulun River at Budun Mountain, Haolaihule Township, Hexigten Banner. Judging from the length of the river, it should be the positive source.

The headwater, also known as the Yellow Water Source, is located in Baicaogou (east edge of Little Tengger Desert) in Haolaihule Township, Keshiketeng Banner, and was called Pingdi Pine Forest in ancient times (called Baier River and Honghe in Mongolian). Kang Qingyuan, a modern scholar, said in Peng Jing County Records of Jehol: "Xilamulun originated from the Baier River flood in Keqi, which is a giant river beyond the Great Wall. It has long been scattered in various local chronicles ... Huangyuan is now called Yuanshuitou. " . It is a depressed gourd-shaped low-lying basin with a flat bottom and lush trees, and dozens of springs spew clean water. Springs meet at the semi-circular Shawan exit, forming a desert river in the sand. After joining Saren River near Goumen Village in Haolai Le Hu Township, Shali Mohe River was officially called Xilamulun River (in the section of Hexigten Banner 169 km, * * there are more than 50 rivers flowing into Xilamulun).

Xiyunggou River originates from Zhengcha, Dongcha and Xicha in Shipeng Village, Shuangjingdian Township, linxi county, and flows into Xilamulun River after confluence in Shi Peng.

Weizigou in the upper reaches of Tang Wei is 1 km long, 30m deep and 50m wide, with steep walls. Tang Wei River is the boundary river between Tuchengzi Town and Wengniute Banner in Hexigten Banner, Inner Mongolia Autonomous Region and Ping 'an Township and shuang miao xiang in Zhangwu County, Fuxin City, Liaoning Province.

Chagan Mulun River (Chagan Mulun River), also known as Heishui River, was called Aozhi River in Sui and Tang Dynasties, Heihe River in Liao Dynasty, Hazi Mulun River in Yuan and Ming Dynasties, and Chahan Mulun River in Qing Dynasty. The upper source comes from the southern foot of Hanshan Mountain in Bahrain Right Banner, a branch of Daxing 'anling Mountains, and joins the Xilamulun River at Huriha Temple, and flows through the southwest of Bahrain Right Banner from north to south to join the Xilamulun River. . The river enters from the southeast of Shimenzi Village, Wujiazi Town, linxi county, flows through Xinglongzhuang Township, Guandi Town and Longping Township, and exits on the east side of Pingdingmiao Village. The domestic flow is 60 kilometers long, the basin area is 1046.9 square kilometers, and the riverbed width is 20- 100 meters. In 23 years (1956- 1979), the average runoff was 36.93 million cubic meters. The river banks are mostly hills and dunes, the riverbed is wide and curved, and the bottom of the river is mostly quicksand, with weak subsidence. In 2023 (1956- 1979), the average annual sediment discharge is 410.5 million tons. The section from Longtoushan to Pingding Temple is more than 20 kilometers, and the riverbed is relatively wide. The velocity of the river overflows and silts seriously, and the riverbed increases year by year, which leads to the salinization of large areas of cultivated land on both sides of the river. In the summer flood season (June-August), the water depth can reach 2 meters, the velocity is 4 meters per second, and the impact force is strong, so the farmland and roads on both sides of the river are often washed away by flooding. Every year 1 1, February and March-April are the freezing and thawing periods of rivers.

The main tributaries of Chagan Mulun River are:

Wuniutai River: It originates at the northwest 1km of Mojiagou in Laofangshen Township, linxi county, flows through Dalengshan Forest Farm, Xiangshuigou Village, Xibianqiang Village, Laofangshen Village, Dongaobao Village and Taipingzhuang Village, and joins Chagan Mulun River in Damajin Village, with a total length of about 30km.

The coastal terrain is flat, mostly farmland and pasture, with curved rivers and serious erosion on both sides. The river bottom is mostly gravel sand, and the sinking force is small. In 23 years (1956- 1979), the average annual sediment discharge was 854,900 tons. This river is the main irrigation river in the central agricultural area of the county, with high utilization rate. During the flood season (June-August), the water depth can reach 3 meters, the velocity is 3.5 meters per second, and the impact is strong, so the farmland on both sides of the river is often washed away by the flood. Every year 1 1, February and March-April are the freezing and thawing periods of rivers. The main tributaries of Gasitai River are: Boligou River, which originates from the southeast of Jilin Ba Village, Xingwang Township, linxi county at 1km, and flows through Li Yong Village, Xingfu Village, Xingwang Village, Dongsheng Village, Zhaojiayingzi Village, Sunjiayingzi Village and Dachuan Village, where toad stone flows into Gasitai River in Wu Wen Village.

The domestic flow is 46 kilometers long and the basin area is 992:2 square kilometers. In 23 years (1956- 1979), the average annual runoff was 29.76 million cubic meters. Most of the riverbanks are flat cultivated land, with wide riverbed, curved river course, some banks are steep, and the river bottom is gravel sand, so the settlement force is small. In 23 years (1956- 1979), the average annual sediment discharge was 386,000 tons. This river is the main irrigation river in the northern agricultural area of this county. In flood season (June-August), the water depth is 1.8m, and the flow velocity is1m/s. Every year,165438+1October, February and March-April are the freezing and thawing periods of the river.
