Where is the source and destination of Bailong River?

The source of Bailong River is in langmusi at the junction of Luqu, Gannan Tibetan Autonomous Prefecture and ruoergai county, Sichuan Province, and the destination is Guangyuan City, Sichuan Province.

Bailong River, originating in langmusi at the junction of Luqu in Gannan Tibetan Autonomous Prefecture and ruoergai county in Sichuan, flows through Luqu in Gannan Tibetan Autonomous Prefecture, ruoergai county in Sichuan Province, Diebu County, Zhouqu County, Dangchang County, Wudu District and Wenxian County in Gansu Province, and joins Jialing River in Guangyuan City, Sichuan Province.

The total length is 576 kilometers, the drainage area is 310.8 million square kilometers, and the annual runoff is10.8 billion cubic meters. Gansu province is 475 kilometers long, with a drainage area of 27,200 square kilometers, an annual runoff of 9.38 billion cubic meters and an annual sediment discharge of184,000 tons.

Hydrological characteristics of Bailong River;

Bailong River has less sediment, dense forests above the two estuaries, good vegetation and small river sediment concentration. According to the test data of Wudu Station, the average sediment discharge for many years is15.5 million tons, and the sediment concentration is 3.7 kg/m3, which mostly occurs in the flood season from July to June, accounting for 78.2%.

Due to the influence of human activities and debris flow, the sediment concentration in the reach from Lianghe to Wudu has greatly increased. The maximum sediment concentration in Wudu is 482kg/m3, and that in Baishuijiang, a tributary, is only 17.7kg/m3.

The water pollution is very light. The annual water quality is Grade II. According to the measured data of 492km river length, the first-class river length is 302km, accounting for 65%, the second-class river length is 107km, accounting for 22%, and the third-class river length is 65km, accounting for 13%.

Bailong River is rich in hydraulic reserves, with a tribal difference of 2,783 kilometers in the main channel and a theoretical reserve of 3,665,600 kilowatts, of which the river gap in Gansu is 267 1 m and the theoretical reserve is1.6500 kilowatts.
