As the largest river in the tributary basin of the Yangtze River, why can t the Jialing River alluvi

The Jialing River basin covers a large area, and the northern part of the Sichuan Basin takes the Jialing River as the main stream, and the gully landform formed at the confluence of the Fujiang River and the Qujiang River. In the west of our country is the first step, the Qinghai-Tibet Plateau and the Sichuan Basin, belonging to two different plates, the Himalayan orogeny, so that the Qinghai-Tibet Plateau plate forms a north-south fault zone, the cave is located in the Chengdu Plain, the Qinghai-Tibet Plateau uplifts, the junction forms a huge gap, in addition, the climate here is humid and rainy, and the rivers are developed, such as the Minjiang River. The upper reaches of the river carry sediment to the lower reaches and deposit it on the Chengdu Plain.

The topographic structure fault zone in western Sichuan, then the northern part of the Sichuan Basin, the geological structure of the northern region is very different from that of the west, and the northern part does not form so many shortcomings, which means that there are no fault zones and fewer fault zones, and it is not easy to form depressions, alluvial plains, and it is not easy to form. Geologically, northern Sichuan is a transition zone from Daba Mountain to a hilly area, forming not steep cliffs, but undulating hills. The tributaries of the Jialing River and other rivers flow through hilly areas with small elevation differences and low erosion, making it difficult for these hilly areas to form open plains.

The main tributaries are the Minjiang River, Jialing River and Tuojiang River in the Sichuan Basin, which is the largest basin in the Jialing River Basin, it is composed of three rivers, the Fujiang River, the Qujiang River and the Jialing River, flows through the hilly area, is shale, sandstone, conglomerate and other lithologic areas, but the sediment concentration of the river is higher, but the sedimentary terrain area in the basin is small, and the mountainous area is low and hilly, and it is difficult to form a larger plain than the Chengdu Plain.

Therefore, the development of rivers alone is not a sufficient condition for the formation of alluvial plains, and corresponding topographic coordination is required to form large plains, which are as flat as whetstones. On the one hand, due to the topography of the lower reaches of the river, as well as the slow flow rate of the river, the sediment is fully deposited, resulting in the great plain, the Sichuan Basin does not have the topography of the Jialing River Basin, and it is crowded within a narrow range, so it is surrounded by mountains, and it is difficult to form a plain.

Because the river field will have different flow directions, will also produce different deposits, will form different tributaries, so there is no way to alluvial plains.

Because the river topography in this place is not good, there is no way to rush out of the plain, and the scenery of the Jialing River is also very beautiful.

Because the Jialing River is not strong enough to break out of a plain, and the speed of the water is not particularly turbulent, this is not possible.

Because the confluence of the Jialing River and the Yangtze River is relatively high, Chongqing is called a mountain city, so it cannot form an alluvial plain.

Which tributary of the river you say alluvizes the plains? Alluvial plains need to have waters below sea level.

The Yuxi Plain is the alluvial plain of the Jialing River, and you can go to Shapingba in Chongqing to see it.

In that place in Chongqing, the Amazon can't rush out of the plain, let alone the Jialing River.

The soil carried by the Jialing River was brought to Shanghai by the Yangtze River.

Because the Sichuan Basin has been rising! It is not possible to form a slow water zone.

Geography books say that the largest tributary of the Yangtze River is the Jialing River, not the Han River. Back to the end.

Before the downstream improvement project of the Han River in the 50s, the basin area was larger than that of the Jialing River, but due to the need for downstream flood control, part of the basin area was directly changed to the Yangtze River.

The flow of the Min River becomes the largest after the Minjiang River flows into the Dadu River and the Qingyi River in Leshan, and it is very close to the mouth of the Minjiang and Jinsha rivers, so the discussion of the Minjiang River usually does not include the Dadu River and the Qingyi River, and the Dadu River, a secondary tributary, is regarded as the same level as the Minjiang River, a first-class tributary, so it is generally considered that the Hanjiang River is the largest tributary of the Yangtze River.

The largest tributary of the Yangtze River is the Han River.

Analysis: There are many ways to determine the maximum tributary of a river, and the three most commonly used methods are calculated according to runoff, length, and basin area

In terms of runoff, the largest tributary of the Yangtze River is the Min River, with an average annual runoff of more than 90 billion cubic meters.

In terms of length, the largest tributary of the Yangtze River is the Han River, with a total length of 1,577 kilometers.

The largest tributary of the Yangtze River is the Jialing River, with a basin area of about 160,000 square kilometers.

There is nothing to do with the Han River at all. The length of the Yalong River is the first, the basin area is the first Jialing River, and the flow is the first Minjiang River. The Han River used to be the longest in the past, but after re-mapping, the Yalong River has surpassed the Han River by more than 100 kilometers, and in terms of area and flow, the Han River has never been the first.

It was more than 2,000 years ago that the Jialing River took the Western Han water, and the Huai Han River was also said before that, after the Western Han River was seized, the Han River was not the largest in any aspect.

Han River. The Han River, also known as the Han River, the Han River, is the largest tributary of the Yangtze River, and the modern hydrology believes that there are three sources: the middle source of Yangshui, the north source of the Fushui, and the south source of the Yudai River, all of which are in the southern foot of the Qinling Mountains, in the territory of Ningqiang County, Shaanxi, flowing through the county (now Mian County) called the water, and flowing east to Hanzhong is called the Han water; The section from Ankang to Danjiangkou was called Canglang Water in ancient times, and Xiangyang was also known as Xiangjiang River and Xiangshui below.

Neither the Jialing River nor the Han River, but the Yalong River.

The Yalong River is the largest tributary of the Jinsha River, also known as Ruoshui, Dachong River, and Xiaojinsha River. One of the rivers with the richest hydropower resources in China. It originates at the southern foot of Bayan Kala Mountain, flows into Sichuan through Qinghai, and enters the Jinsha River at Sanduizi in Panzhihua City.

Above the stone canal is the Shiqu River, which flows through the hilly plateau area, the riverbed is wide and shallow, and the water flow is diffuse. The stone canal is called the Yalong River, which is one of the main river systems in the north-south direction of the Hengduan Mountains due to the gradual entry into the alpine valley area due to the mountainous landform. The total length is 1,571 km, 1,357 km in Sichuan, the basin area is 10,000 square kilometers, and the average annual flow of the estuary is 1,860 cubic meters per second.

The Jinsha River is the upper reaches of the Yangtze River in China. It is named because the sandy soil in the river is yellow.

After the Jialing River enters the Sichuan Basin, the slope decreases rapidly, and the river flow speed slows down rapidly. The possibility of a straighter river that could be flushed out by inertia no longer exists.

While the flow rate of the river slows down, the meandering section of the Jialing River has a rock formation close to horizontal, and there are also many extremely soft rock formations such as mudstone and siltstone. It is precisely because of the soft bottom of the riverbed that the geostrophic deflection force, which is not dominant, has become the key to controlling the direction of the river.

Although the Sichuan Basin is a basin, specifically it is now a hill, but before the ancient Himalayan orogeny, there was no doubt that it was a great plain, and the twists and turns of the Jialing River were formed at that time.

Han River. The Han River, also known as the Han River, the Han River, is the largest tributary of the Yangtze River, and the modern hydrology believes that there are three sources: the middle source of Yangshui, the north source of the Fushui, and the south source of the Yudai River, all of which are in the southern foot of the Qinling Mountains, in the territory of Ningqiang County, Shaanxi, flowing through the county (now Mian County) called the water, and flowing east to Hanzhong is called the Han water; The section from Ankang to Danjiangkou was called Canglang Water in ancient times, and Xiangyang was also known as Xiangjiang River and Xiangshui below.

The Jialing River was originally the source of the Han River, and in the Han Dynasty, the Jialing River was diverted to Sichuan. It is proposed to divert the Galing River into the Han River now.

The Jialing River flows into the Yangtze near Chongqing, and the Han River flows into the Yangtze near Wuhan, so they are both tributaries of the Yangtze River.

The Han River, the largest tributary of the Yangtze River, is also known as the Han River.

The Han River originates near Ningqiang County in southwestern Shaanxi Province, China. The upstream is called the water, also known as the frustrated water. After flowing to Hanzhong City, it is called the Han River, to the east of Chenggu County, converging from the water of Taibai Mountain, the main peak of the Qinling Mountains, after flowing eastward into Hubei, it receives the Danjiang River in the east of Danjiangkou City, and inherits the water of Tangbai River in Xiangfan City.

After Xiangfan City, it turns south, passes Zhongxiang City, enters the Jianghan Plain, changes to the east in the north of Qianjiang River, and finally enters the Yangtze River in Wuhan City.

The Hanjiang River basin covers an area of 10,000 square kilometers and is 1,577 kilometers long. Xiangfan City, Hubei Province is also known as Xianghe River. From its source to the junction of Shaanxi and Hubei provinces, the Hanjiang River runs between the Qinling Mountains in the north and the Micang Mountains and Daba Mountains in the south, passing through the Hanzhong Basin, with abundant water.

Entering below the Jianghan Plain, the slope of the river decreases, the flow speed decreases sharply, and the waterway twists and turns, tossing and turning between the dotted lakes, forming a water town and Zeguo. There are 154 tributaries with hydropower reserves of more than 10,000 kilowatts.

The total annual runoff of the Han River is 53.9 billion cubic meters. The upper reaches pass through the Hanzhong Basin, which is rich in water; The meandering stream in the middle reaches is developed, because it is slow with the Yangtze River, and there are many sandbanks and pebble beaches; The meandering stream in the lower reaches is developed, and because the river and port are staggered with the Yangtze River, it often meets the flood peak of the Yangtze River during the flood season, and floods.

The Han River, a tributary of the Yangtze River, is one of the most severely flooded rivers. In 1935, a major flood drowned 120,000 people along the river.

After the founding of the People's Republic of China, the Danjiangkou Water Conservancy Project, the Hanbei Large-scale Flood Drainage Project, and the Dujiatai Flood Diversion Project were built, which basically eliminated flood and drought disasters and developed power generation, irrigation, and shipping industries.

According to the historical records, "The Book. Yu Gong": "The mound guides the eastward flow for the Han Dynasty.

Jiaqing is unified. Hanzhong House. Mountains and Rivers:

Hanshui, in the north of Ningqiang Prefecture, comes from the Lingzuka Mountain. It flows east through the south of Chu County, and east through the south of Baocheng County, and east through the south of Fuzhi South Zheng County. It flows southeast into the boundary of Shiquan County, Hung Yen Province. ”

The Han River is the longest tributary of the Yangtze River, with a length of 1,577 kilometers.
