2020年7月1日至7月7日,安徽省江北与皖南地区受到北方南下的冷锋和南方北上的的暖湿气流的共同影响,流域普降大到暴雨,局部地区特大暴雨。水阳江流域受影响较大,建议合理增加水阳江流域支流域中小河流巡测流量断面,尽快实施基本水文站在线流量开发与推广应用,及时为防汛部门提供准确水文信息。

From July 1 to July 7,2020,Jiangbei and Wannan regions in Anhui Province were jointly affected by the cold front moving southward from the north and the warm and humid air flow moving northward from the south,resulting in heavy rain to rainstorm in the basin,and extremely heavy rainstorm in some regions.The Shuiyang River Basin has been greatly affected.It is recommended to reasonably increase the flow measurement cross-section of small and medium-sized rivers in the Shuiyang River Basin tributary basin,implement the online flow development and promotion application of basic hydrological stations as soon as possible,and provide accurate hydrological information for flood control departments in time.
