Guangdong rainstorm:
From the evening of June 20th, there was a large-scale general rainstorm in Shaoguan, Qingyuan and other places, especially from the early morning of this morning, Yingde dropped by 25 1mm in 7 hours and nearly 300mm in 24 hours, breaking the historical record.
So far, in the first 20 days of June, the total precipitation in Yingde has exceeded1200mm; The 30-day average rainfall in Shaoguan reached nearly 700 mm, nearly 2.5 times that of the same period of the previous year, all of which set a new record. So much precipitation has finally formed a torrent, which flows into an important river in Guangdong and one of the main rivers in the Pearl River, the "Beijiang River".
Beijiang River originated in Nanling, covering most areas of Shaoguan and Qingyuan, as well as some counties and cities in Guangzhou, Foshan, Zhaoqing and Heyuan. It is one of the most important water systems in Guangdong Province. Because of its centripetal water system structure of vein type, if there is heavy rain in Beijiang River basin, the floods of tributaries will rush into the main stream, making the flood peak "traffic jam", thus making the water level of the main stream rise sharply.
Because of this, Beijiang River is also a river with high flood control pressure in Guangdong Province, and Beijiang levee is one of the most important flood control levees in Guangdong. Historically, the Beijiang River was flooded frequently. The biggest floods in the past 30 years were 1994 and 2006, which were caused by Typhoon Ruth and Typhoon Bliss respectively. At that time, the water levels in Yingde reached 34.5 1 and 34. 19 meters respectively.
But this time, the flood has far exceeded 1994 and 2006. The latest data on the evening of June 2 1 shows that the water level in Yingde has risen to 35.13m, ranking first in the actual measured record, second only to the investigated water level 193 1 and 19 15. The peak flow of Shijiao Station reached 17600 m3/s, a new record since the establishment of 1924 Station.
