An analysis of storms and floods occurring in the Pearl River Basin in April 2024
A comprehensive analysis and summary are conducted on the causes of rainfall,rainfall process,rainfall characteristics,flood process,flood composition,flood characteristics and the impact of water projects,by taking a series of rainstorm and flood processes in the Pearl River basin in April 2024 as the research object.The results reveal that there are five heavy rainfall processes in the Pearl River basin in April 2024,which are characterized by several heavy rainfall events,long duration,large cumulative rainfall and wide impact range.The Pearl River Basin endured six numbered floods in the Beijiang,Dongjiang,and Hanjiang rivers due to the persistent heavy rainfalls.This series of flood processes has the characteristics of early occurrence,large magnitude,and high frequency.The coordinated operation of flood projects in the basin achieved significant flood benefits,during this flooding process,minimizing flood pressure along the basin,and effectively ensuring the flood safety in important areas.
