What has the Qiantang River Tide been called since ancient times?

The Qiantang River tide has been known as a wonder of the world since ancient times. The Qiantang River is located in Zhejiang Province, my country, and eventually flows into the East China Sea. The tide at its estuary is world-famous, and many tourists come to watch this wonder every year. Before the tide arrives, a tiny white dot appears in the distance, and in the blink of an eye it turns into a silver line, accompanied by bursts of thunder-like tide sounds, and the white line rolls in. There is almost no time for people to react, and the surging tide has roared in, with a peak of 3 to 5 meters, and the waves behind are chasing the waves in front, one layer after another, like a long white ribbon, with a great momentum of overwhelming mountains and seas. The poem says: "Qiantang is full of waves, and the raging waves are in front of you in an instant; the seemingly ordinary river water contains energy that can shock the world." The tide head comes from far to near, galloping, pushing and pushing, the sound is like thunder, spraying pearls and splashing jade, and the momentum is like a galloping horse.

Is Qiantang River fresh water or salt water?

Freshwater. Qiantang River is the largest river in Zhejiang Province, China. It originates from Huangshan Mountain in Anhui Province and flows through Anhui and Zhejiang Provinces. Its ancient name is "Zhejiang", also known as "Zhejiang" or "Zhijiang". It was first mentioned in "Classic of Mountains and Seas". Its basin is one of the main birthplaces of Yue State and Wuyue Culture. The river is 688 kilometers long and has a basin area of ​​55,600 square kilometers, accounting for more than half of the provincial area. The average annual flow is 44.25 billion cubic meters, and the theoretical reserve of tidal hydropower resources at the estuary is 4.72 million kilowatts. The Qiantang River tide is known as "the best tide in the world".

What causes the Qiantang River to rise in tide?

Causes of Qiantang River Tide:

1. In terms of weather, from the 16th to the 18th day of the eighth lunar month, the sun, the moon and the earth are almost in a straight line, so the tidal force on the sea water is the greatest on this day.

2. Geographical advantage: Nearly 500,000 mu of reclaimed land east of Zheshan on the south bank of Qiantang River blocks the river mouth like a peninsula, making the Qiantang River section from Zheshan to the outer 12 kilometers look like a bottle with a big belly and a small mouth. The tide is easy to enter but difficult to retreat. The outer mouth of Hangzhou Bay is 100 kilometers wide, but it is only a few kilometers wide in the outer 12 sections. The riverbed in the eastern section of the river mouth rises suddenly, and the beach is high and the water is shallow. When a large amount of tide rushes in from the mouth of Qiantang River, the river surface shrinks rapidly, so the tide has no time to rise evenly, so the waves behind push the waves in front, layer by layer. Secondly, it is also related to the large amount of sediment under the water of Qiantang River. These sediments block and rub the tide, making the front slope of the tide steeper and the speed slower, thus forming the wave behind chasing the wave in front, one wave after another.

3. Wind: Southeast wind often blows along the coastal areas. The wind direction is roughly consistent with the direction of the tide, which contributes to the tide.
