数字赋能海河“23·7”流域性特大洪水防御

Digital enables the Haihe River“July 23”basin-wide catastrophic flood prevention

2023年海河发生流域性特大洪水。水利部门锚定“四不”目标,推进数字孪生流域建设,强化流域防洪“四预”措施,为打赢海河“23·7”流域性特大洪水防御战提供了坚强支撑和保障。分析了海河“23·7”流域性特大洪水雨水情特点,介绍了数字孪生海河应用情况,总结了流域防洪“四预”实践成效,检视了存在的问题,并提出了改进措施。

In 2023,the Haihe River suffered a basin-wide catastrophic flood.Aiming to provide strong support and guarantee for the“July 23”basin-wide catastrophic flood,water conservancy department focus on the goal of“no casualties,no collapse of reservoir dams,no breach of important dikes,and no impact on important infrastructure”,promote the application of the digital twin basins,enhance the functions of making forecasts,issuing early warnings,conducting simulations and drafting contingency plans in basin-wide system for flood control.This paper concentrates on the“July 23”basin-wide catastrophic flood in the Haihe River Basin,briefly analyze the main characteristics of rain and water situations,introduces the development of digital twin for the Haihe River Basin,summarized the practical efforts on making forecasts,issuing early warnings,conducting simulations and drafting contingency plans in river basin flood control,examines the existing problems and puts forward improvement measures.
