2024年富水流域梅雨期暴雨洪水特征及调度初探
Preliminary Analysis on Characteristics and Dispatching of Rainstorm and Flood during 2024 Meiyu Period in Fushui River Basin

富水水库是一座以防洪、发电为主，结合灌溉、航运等综合利用的大(1)型水利枢纽工程。2024年梅雨期，富水流域遭受了3轮强降雨过程，干流洪水涨势快、量级大、历时长，水库一度开启7孔闸门泄洪，为建库60多年来第二次。水库最大7 d入库洪量超过20 a一遇，科学调度后明显降低流域防洪压力；经还原分析，水库拦洪削峰率约62.7%，明显推迟了下游干流堤防超保证水位时间。本文选用2024年梅雨期暴雨进行了洪水特征分析，为今后出现类似事件提供水库调度运行管理等借鉴参考。
Fushui Reservoir is a large (1) type water conservancy hub project that focuses on flood control and power generation, combined with comprehensive utilization such as irrigation and navigation. In 2024 Meiyu period, the Fushui River Basin experienced three rounds of heavy rainfall. The floods in the Fushui main stream rose rapidly, with large magnitudes and long durations. Once the Fushui Reservoir opened seven gates for flood discharge, marking the second time in over 60 years since its construction. The maximum 7-day inflow of Fushui Reservoir exceeds once every 20 years. Through scientific scheduling, the flood control pressure in the basin has been significantly reduced. According to the analysis of restoration, the flood control and peak shaving rate of the reservoir is about 62.7%, which significantly delays the duration of downstream embankment exceeding the guaranteed water level. In this paper, the rainstorm in 2024 Meiyu period is selected to analyze the flood characteristics, providing reference for similar events and reservoir operation and management.
