Analysis of Sluicing Characteristics of Backwater Flow in Sammenxia Reservoir
摘要
Abstract
In this paper,the field data of Sanmenxia Reservoir in 1964-2006,including 53 sets in the non-flood period and 144 sets in flood stor-age,backwater flow flushing was analyzed,and the relationship between the outflow sediment concentration and inflow sediment concentration and retention time were put forward. The results show that the average concentrations of inflow and outflow in non-flood period,8 and 5 kg/m3 respec-tively,are lower than the concentrations,20-40 kg/m3 ,that is required in the lower reaches of the Yellow River during the water and sediment regulation,and the outflow concentrations of 24% floods,with the average discharge 1 200 m3/s and the average concentrations of inflow and out-flow 32 and 24 kg/m3 ,are in the scope of the concentration that is required in lower reach of Yellow River during the water and sediment regula-tion. The outflow discharge and corresponding sediment concentration from the reservoir of 2. 8% floods are in the range of index in the Yellow Riv-er downstream during the water and sediment regulation.关键词
