When is Tide Watching Day

The eighteenth day of the eighth month of the lunar calendar is the annual tide-watching day.

On the day of tide watching, especially on the 18th day of the 8th month of the lunar calendar, the road is as busy as the water, and the people are as busy as the tide. A distance view of the Qiantang River out of the sea trumpet, the tides form a raging wave, like a million horses, meet placebo near the riverbed sand can be blocked, the tide lifted three to five meters high, the tide difference of up to nine to ten meters, there is a "monstrous turbid wave rows of empty air to come, overturning the mountain can be destroyed" of the trend.

Qianjiang River tide is located 45 kilometers northeast of Hangzhou Haining Yanguan town. Such a magnificent landscape, there are only two places in the world, one is the Amazon River in Brazil, South America, one is the Qiantang River. For the ancient and modern Chinese and foreign tide watchers, known as "the world's wonders".

Expanded

Magnificent Qiantang River tide cause in addition to the moon, the sun gravitational influence, but also with the mouth of the Qiantang River is like a trumpet shape. Qiantang Jiangnan Ochishan east of nearly 500,000 acres of reclaimed land like a peninsula like blocking the mouth of the river, so that the Qiantang River Ochishan to the outside of the twelve work section is like a bottle with a big mouth, the tide is easy to get in and out of the Hangzhou Bay mouth as wide as 100 kilometers to the outside of the twelve work section is only a few kilometers wide.

East section of the riverbed and the mouth of the river suddenly rise, beach high water, when a large number of tide from the mouth of the Qiantang River, due to the rapid narrowing of the river, so that the tide can not rise evenly, it is necessary to push the front of the wave, the front of the wave can not run fast, the back of the wave to catch up with the layers of the overlapping. Secondly, with the Qiantang River underwater more sediment related to these sinking sand on the tide to block and friction effect, so that the tide before the slope becomes steeper, slows down, thus forming a wave to catch up with the previous wave, a wave stacked a wave, a wave of a wave high surge tide.
