Excuse me, can Hangzhou see the Qiantang River tide?
There are several tide-watching spots in Hangzhou, such as Xiaoshan City, Xiasha Bridge, Qibao, Sanbao, City Balcony, Nanxing Bridge, Zhakou, Jiuxi and Wenjiayan.
Qiantang River in Hangzhou is a tidal observation station without any obstacles. Cars can drive near the dam, and Xiashazige, Jiubao and Jiuxi are the best observation points. When the moon is full, it must be a spring tide. Every month from the first day to the sixth day of the lunar calendar, it is a spring tide.
Extended data:
Causes of spring tide in Qiantang River;
1. Of course, the cause of the spring tide in Qiantang River is also inseparable from celestial movement. From August 16 to August 18 in the lunar calendar, the sun, the moon and the earth are almost in a straight line, so the sum of the gravitational forces generated by the centrifugal motion of the sea water and the moon is the largest. Coupled with the deflection angle and rotation movement of the earth itself, the phenomenon of seawater rising tide is more obvious.
2. Nearly 500,000 mu of land reclamation east of the south bank of Qiantang River blocked the estuary like a peninsula, making Qiantang River like a bottle with a small belly and a big mouth, and the tide is easy to enter but difficult to retreat. When there are a large number of tidal bore in the mouth of Qiantang River, because of the small river surface, the water can not rise evenly, so we have to use the back wave to push the front wave and stack it layer by layer to form the tidal bore.
3. Qiantang River is located in Hangzhou Bay, where the Pacific tidal waves come straight from the east and the tidal range on the west coast of the East China Sea is the largest. Therefore, various reasons come together and contribute to the tidal bore of Qiantang River.
