China News Service, Hangzhou, September 18 (Zhang Bin, Hu Ding and Chen Yiru) "Why is this in Zhejiang in August? The waves are like snow blowing from the mountains." On the eighteenth of the lunar calendar, the tide of the Qiantang River will arrive as scheduled.
On the 18th, the 2020 Qiantang River Tide Prevention Safety Management and August 18 Tide Forecast Press Conference was held in Hangzhou, Zhejiang.
That day was the second day of the eighth lunar month, the last flood day before the Qiantang River tide.
The reporter was informed that under normal weather conditions, on August 18 of the lunar calendar this year, the tidal surge on the Qiantang River will be greater than last year, or the largest tide in the past three years.

It is reported that the formation of the Qiantang River tide is related to the right time and place: from the 16th to the 18th of the lunar calendar, the earth, moon, and sun are arranged almost in a straight line. The seawater receives the greatest tidal force, and it flows back into the trumpet-shaped Qiantang River mouth, which is easy to enter and hard to retreat. , So the tide is formed.

Huang Jianyong, member of the Party Committee and Deputy Director of the Hangzhou Forestry and Water Conservancy Bureau, said that due to the long rainy season this year, the 9-hole flood discharge of Xin'anjiang Reservoir, and the continuous large-flow discharge of Fuchunjiang Reservoir, the lower reaches of the Qiantang River have been more scoured. Deeper, the river bed is lowered, and the seawater will flow back more, which is conducive to the formation of a more spectacular tide.

"Qiantang River tides do not only appear on the eighteenth day of the lunar calendar." Zhang Zhenlin, deputy director of Hangzhou Hydrology and Water Resources Monitoring Center, introduced that Qiantang River tides are twice a day with 12 hours apart. The day after the tide will be delayed compared to the previous day. Appears in half an hour, and cycles in half a month.
The tide of the Qiantang River is especially large from the first to the fifth day of the lunar calendar, and from the fifteenth to the twentieth day. There are about 120 tide-watching days in a year. July, August, and September are the best times for tide-watching.
