Why does the river flow eastward? Is there a river that flows west?

First of all, most rivers flow eastward mainly because of two factors:

1 has something to do with the topography of China.

China's topography is high in the west and low in the east, which is generally stepped and influenced by gravity. Therefore, water flows downward, that is, eastward, extending to the ocean, which is conducive to the moist airflow on the ocean going deep into the mainland, thus bringing rich water vapor. This topography, which is high in the west and low in the east, makes many big rivers in China flow eastward, connecting east and west traffic; It also makes many large rivers flow rapidly from high cascade to low cascade, resulting in huge hydropower resources.

2. It has something to do with the direction of the earth's rotation.

Because the earth turns from west to east, the water on the earth also flows from west to east due to the inertia of the earth's rotation.

Second, there is a river that flows west.

1. The Daotang River in Qinghai Province is really an east-west river.

It is said that the Tanghe Valley is the ancient channel where the Buha River flows into the Yellow River during the geological period. Due to the strong uplift of the earth's crust, its speed exceeds the downward cutting speed of the river, so the outlet of Gubuha River is blocked and the river flows back to Qinghai Lake, thus forming the internal flow environment of Qinghai Lake basin.

For example, in Europe, the Rhine and Danube both flow westward.

The Rhine is the largest river in western Europe, which originates from the northern foot of the Swiss Alps, flows through Liechtenstein, Austria, France, Germany and the Netherlands in the northwest, and finally flows into the North Sea near Rotterdam. The Rhine, with a total length of1.232km, is a famous international river in Europe, leaving footprints of Liechtenstein, Austria, France and the Netherlands along the way. Since the 18 15 Vienna Conference, it has become an international shipping waterway, with the longest navigable length of about 869 kilometers (540 miles) and as far as Feilden Rhine on the Swiss-German border. The basin area (including the delta) exceeds 22,000 square kilometers (85,000 square miles).

The Danube River is located in the southeast of Europe, and originated in the Black Forest region of Germany. To the south of the river are Alps, Velebit Mountain, Dinara Mountain, Laoshan Mountain and balkan mountains. There are Czech Forest Mountain, Shumawa Mountain, Sudede Mountain and Carpathian Mountain in the north. The main plains of the Danube include Vienna Plain, Hungary Plain, Wallachia Plain and Danube Plain. The Danube is 2,857 kilometers long, with a drainage area of 810.7 million square kilometers and an average flow of 6,500 cubic meters per second.

The Danube has played an extremely important role in the settlement, migration and political changes in Central and Southeast Europe. The castles and forts arranged on both sides of it form the dividing line between the great empires; However, its waterway is a commercial channel between countries. In the 20th century, it continued to play the role of trade artery.
