摘要：
Based on the field data, the characteristics of the peak of the sediment concentration history of the Three Gorges Reservoir in flood seasons were studied, e. g., the traveling time (TT) and the reduction ratio after passing through the dam (RR), which may relate to several different factors. First, the theoretical deduction and the stepwise regression were combined to analyze and find the major factors which determined the TT and the RR of the peak of the sediment concentration history. Second, the regression analysis and curve fitting were used to establish the formulas for the TT and the RR and its parameters. Third, the performances of these new formulas for the TT and the RR were validated by the field data. The properties of the sediment transport of the Three Gorges Reservoir in flood seasons was then studied, whose results may provide references for the operation of the Three Gorges Reservoir. © 2019, The Editorial Board of Journal of Basic Science and Engineering.
