摘要
通过系统分析黄河中下游场次洪水的时间、空间、水量、沙量等因子和形成条件,研究提出中小洪水水沙分类指标,将中下游洪水分为5种类型。针对下游滩区减灾与水库、河道减淤要求,研究小浪底水库拦沙库容多元化利用方法,分析比较不同管理模式对水库和下游的长期影响,提出高含沙洪水敞泄,非高含沙量洪水随小浪底库区淤积量、下游保滩库容需求量逐级控泄的分类管理模式。
Based on the systematic analysis of factors such as time,space,water quantity,sand quantity and formation conditions of the middle and lower reaches of the Yellow River floods,the Water-sediment classification indexes were put forward,and the floods were divided into five types.For floodplain disaster reduction and the reservoir,river channel sedimentation reduction requirements,research sediment retaining capacity of the Xiaolangdi reservoir diversified utilization method.By analyzing and comparing the reservoir and downstream of long-term effects of different management mode,a classification management mode of hyperconcentrated floods open discharge,or else control based on xiaolangdi reservoir sedimentation capacity for floodplain disaster reduction was put forward.
