Objectives of the study
For the purpose of profoundly assimilating lessons from the catastrophic “7.20” rainstorm disaster in Zhengzhou, Henan Province, and effectively enhancing the extreme flood prevention and response capabilities of Rizhao City, this study transplants the extraordinary rainstorm event to the Futuan-river Basin in Rizhao. Simulative calculations are performed to assess the potential floods triggered by this rainstorm pattern. Building upon the existing engineering conditions, flood defense strategies and dispatch plans, the study extrapolates and analyzes the potential impacts on reservoirs, river channels, and flood detention areas. This foundational work is aimed at ensuring preparedness for extreme rainstorm disasters. It encompasses the formulation of emergency response plans, pre-disaster drills, and flood season rehearsals. Through these efforts, the study seeks to enhance Rizhao City‘s capacity to effectively address extreme rainfall events and mitigate flood disasters.
