The formation of spring tide in Qiantang River

Qiantang River is the largest river in Zhejiang Province and flows into Hangzhou Bay. The reason why the spring tide of the Qiantang River is particularly magnificent is because of the special topography of the Qiantang River's outlet. The mouth of the sea is hundreds of kilometers wide. When it reaches Kanpu, it shrinks to twenty kilometers. When it reaches Yanguan Town, the river channel suddenly shrinks to about three kilometers. Therefore, it is wide on the outside and narrow on the inside, forming a trumpet shape. When the tide comes, a large amount of seawater is pushed into the river with a flow rate of ten meters per second. Due to the sudden narrowing of the river inside, a large amount of tidal water was caught between the two banks. In addition, the river bed in this area was also very different in height. As a result, the river water flowing eastward impacted the tidal water coming from east to west, and the waves in front overlapped each other, crowding each other. , accumulation, the river channel is the narrowest when entering Yanguan Town, forming the highest peak. As a result, a wall of white water several meters high was created, forming a world-famous wonder at home and abroad.
