Abstract:From July 6 to 9, 2024, the Yishu River Basin suffered a historically rare extreme torrential rain event. Through scientific scheduling and effective disposal, all types of reservoirs, sluice dams, main rivers and other water facilities in Linyi operated stably basically without major dangerous situations. This paper introduces the countermeasures in Linyi in response to the extreme torrential rain in the basin, summarizes the existing problems and experience in the prevention process, and puts forward improvement suggestions, aiming to provide references for the prevention of similar extreme torrential rain events.
