摘要
2020年汛期大伙房水库流域降雨频繁,后汛期洪量创下历史极值,为更好地认识流域暴雨洪水特征及影响因素,为以后水库科学调度提供借鉴,本文从流域暴雨的特点、时空分布和洪水的特征、频率及洪水调度等方面进行了分析,得出以下结论:汛期降雨历时短,单点降水强度大,降雨时空分布不均;主汛期降雨偏少,后汛期暴雨频繁,旱涝急转明显;大伙房水库优化调度方案在确保水库和下游防洪安全的前提下,实现了雨洪资源化。
The rainfall in Dahuofang Reservoir Basin is frequent in 2020 flood season.The record of the flood historical extremum is achieved in the post-flood season.The characteristics of basin rainstorm,space-time distribution and the characteristics of the flood,frequency,the flood dispatching and other aspects are analyzed in the paper for better understanding watershed storm flood characteristics and influencing factors,providing reference for reservoir scientific scheduling in the future.The following conclusions are obtained:the rainfall duration in flood season is short,the single-point precipitation intensity is large,and the spatial and temporal distribution of rainfall is uneven.The rainfall in the main flood season is less.The heavy rain is frequent in the post-flood season.The resource-based utilization of stormwater is realized according to the optimal operation scheme of Dahuofang Reservoiron the premise of ensuring the flood control safety of the reservoir and downstream area.
