Study on flood scheduling of Centianhe Reservoir in Hunan Province in response to extreme rainstorm

In order to improve the flood scheduling capacity of the control reservoir in response to extreme rainstorm in the basin, taking the flood scheduling practice of Centianhe Reservoir in Hunan Province in response to extreme rainstorm in the Xiaoshui River Basin in the upper reaches of the Xiangjiang River Basin in mid to late June 2022 as an example, on the basis of comprehensive analysis of the characteristics of rainfall regime in the basin, this paper summarizes the main experience and practices of flood scheduling, analyzes the main problems, and puts forward the countermeasures and suggestions for improving the flood control capacity of the Xiaoshui River Basin in the future, with a view to providing some experience for the flood scheduling of the control reservoirs in small and medium-sized basins in response to extreme rainstorm.
