Does anyone know the detailed information of the Han River, the largest tributary of the Yangtze River?

Han River

Also known as Hanshui. The longest tributary of the Yangtze River. It originates from the Zhongshan Mountain in Ningqiang County between the Qinling Mountains and Micang Mountain in southwestern Shaanxi Province. It crosses the Qinba Mountains to the southeast, flows through southern Shaanxi and the Danjiang Reservoir in northwestern Hubei, and continues to flow southeast after leaving the reservoir, passing Xiangfan, and joining the Yangtze River in Wuhan City. The total length is 1,532 kilometers and the drainage area is 151,000 square kilometers. The main tributaries are: Baohe River, Danjiang River, Tanghe River, Baihe River, Duhe River, etc. The Han River is winding and winding, and it has been said since ancient times that "the rivers are as winding as those of the Han River". Above Danjiangkou is the upper reaches, with towering mountains on both sides, many canyons, fast currents, large water volumes, and rich water energy resources; from Danjiangkou to Zhongxiang is the middle reaches, flowing through low mountains and hills, and after receiving the Nanhe River and Tangbai River, the water volume and sediment content increase greatly. , there are many sandbars and rocky beaches, and the river channel is unstable; below Zhongxiang is the downstream, winding around the Jianghan Plain, with a small riverbed slope, slow water flow, developed meanders, crisscrossed river branches, and the closer to the river mouth, the narrower the river channel, taking on the shape of an inverted trumpet. , The flood discharge capacity is poor and it is easy to burst into disasters. Among the tributaries of the Yangtze River, the Han River is the one with the most severe flood disasters. The poet Li Bai once expressed his admiration for it, "The whole of China was destroyed across the country, and Cui Wei flew so fast." After the founding of the People's Republic of China, in order to conquer the Han River, the Dujiatai flood diversion area was built downstream in 1956, and the Danjiangkou and Huanglongtan water conservancy projects were built in 1958. The Danjiangkou Hydraulic Hub has comprehensive benefits such as flood control, irrigation, power generation, shipping, and breeding. The Dujiatai Flood Diversion Area and the Danjiangkou Reservoir cooperate to basically eliminate the threat of floods in the lower reaches of the Han River. The Han River is the main water transport trunk line in southern Shaanxi Province and Hubei Province. The industry and agriculture in the basin are developed, and the Jiaozhi, Xiangyu, Handan and other railways that connect the coal-producing bases intersect with it. In order to increase the transportation capacity of coal, industrial products, etc., it was listed as the largest inland waterway improvement project in my country during the "Seventh Five-Year Plan" period. At present, the navigation capacity of Hanshui River has increased from 100 tons to 1,000 tons, and the annual throughput has increased from more than 300,000 tons to more than 10 million tons.

The Han River, also known as the Han River, is 1,532 kilometers long and has a drainage area of ??174,300 square kilometers. It is the largest in the Yangtze River of tributaries.

Introduction

The Han River originates from Panzhong Mountain in Ningqiang County, Shaanxi Province, flows from west to east into Hubei, and then flows into the Yangtze River in Wuhan. The route includes Xushui River, Xunhe River, Duhe River (the largest), Danjiang River, Tangbai River, etc. It passes through major cities such as Hanzhong, Ankang, Shiyan, Xiangfan, and Wuhan. There is the Danjiangkou Reservoir on the Han River, which is the head of the middle line of the South-to-North Water Diversion Project.

History

"Shu. Yu Gong": "The tombs led the Yangtze River to the east and became the Han Dynasty."

"Jiaqing Unification Chronicles. Hanzhong Prefecture. Mountains and Rivers" : "The Han River, in the north of Ningqiang Prefecture, originates from Jizhong Mountain. It flows eastward through the south of Mian County, then eastward through the south of Baocheng County, eastward through the south of Fuzhi County, south of Zheng County...and flows into the Shiquan of Xing'an Prefecture in the southeast. County boundary. ”

Due to changes in terrain and geography, the upper reaches of Ankang of the Han River are no longer navigable, and the tributaries are dry in winter. Some cities in the middle and lower reaches of the Han River are low-lying, and the overflow of the Han River brings huge disasters. In 1983, Ankang City suffered huge losses due to the overflow of the Han River.

Tributaries: Tangbai River, Xiaoqing River, Houzi River

Important cities in the basin: Hanzhong, Ankang, Shiyan, Nanyang, Laohekou, Xiangfan, Wuhan
