How deep is the Jinsha River,

Jinsha River is located in the upper reaches of the Yangtze River, with a dangerous terrain, with the deepest point reaching 60 meters. This is a good place to travel.

Jinsha River runs through Sichuan, Tibet and Yunnan provinces, where Yalong River, the largest tributary, flows, and Nanming River in Yibin, Sichuan Province began to be called Yangtze River. The total length of the main stream from Heyuan in Qinghai Province to Yibin City is 3481km (3,364 km), with a drainage area of 502,000 square kilometers (473,200 square kilometers), accounting for about 26% of the Yangtze River drainage area. The average annual flow is 4750 cubic meters per second. It is mainly supplemented by precipitation, groundwater and snowmelt water. ?

The Jinsha River has a drop of 3,300 meters (5 100 meters), and its hydraulic resources exceed 1 100 million kilowatts, accounting for more than 40% of the Yangtze River's hydraulic resources. The main stream is planned to carry out multi-stage cascade hydropower development. Jinsha River is steep and steep, with breathtaking river course and difficult navigation.

Geographical conditions of Jinsha River

Jinsha River Basin includes the eastern part of Qinghai-Tibet Plateau and Hengduan Mountain Area, the northern Yunnan Plateau in the south, the southwestern edge of Sichuan Basin in the east, and the latitude from north to south is above 9 degrees. The terrain is extremely complex, with many mountains and deep valleys side by side, and the height difference between peaks and valleys can reach 1000-3000m. Therefore, the climate in the basin not only changes greatly in time and space, but also is very significant.

The general circulation situation in the basin is mainly influenced by the westerlies in the winter half year (from June 10 in the northern section of Hengduan Mountains to May of the following year, and from June1/kloc-0 in other areas to April of the following year). Westerly jet, which is divided into north and south branches by the Qinghai-Tibet Plateau, passes through its south branch, bringing sunny and dry weather to the mainland. The northeast of the basin is wet and rainy due to the influence of Kunming stationary front and southwest airflow.

In the summer half year (June-September or May-65438+1October), the westerly belt moved northward, and was influenced by the maritime southwest monsoon and southeast monsoon, which brought abundant precipitation and gradually decreased from southeast to northwest of the basin.
