摘要
2022年6月,华南地区连续出现4次强降雨过程,粤北韶关、清远暴雨突破历史极值,珠江流域发生流域性较大洪水,其中北江为1915年以来最大洪水。介绍了2022年6月珠江流域雨水汛情概况,运用实测资料分析、水文分析、遥感反演等手段,从雨情、水情、灾情三方面,将北江流域2022年6月洪水与1915年7月洪水进行了初步对比,分析了北江防洪工程体系建设及调度效果。
In June 2022,there were four consecutive processes of heavy rainfalls in the Southern part of China.The rainstorms in Shaoguan and Qingyuan in north Guangdong broke the historical record,and a basin-wide flood occurred in the Pearl River Basin,of which the largest flood since 1915 occurred in the Beijiang Basin.With introductions on the general situation of floods in the Pearl River Basin in June 2022,observed data evaluation,hydrological analysis and remote sensing inversion are adopted to compare the floods of the Beijiang Basin in June 2022 with the flood in 1915 from three aspects of rain,water and disaster.Evaluations are also made on the formation of flood control system in the Beijiang Basin and results of dispatching.
