摘要: 考虑水沙输移过程中的非恒定性,建立了三峡水库一维非恒定水沙数学模型。此模型为一树状河网模型,可以将更多支流纳入计算范围。采用三峡水库蓄水运用后2003-2009年实测水沙资料对模型进行了验证计算,计算结果与实测资料符合较好,表明模型能够用于三峡水库干支流河道水沙输移数值模拟。该模型可在今后三峡水库优化调度等相关研究工作中发挥其模拟和预测作用。

Abstract: A numerical model for simulating unsteady flow and sediment transport in the mainstream and its tributaries of the Three Gorges Reservoir (TGR) area was presented in this paper. More tributaries could be included in the calculation with this tree-like rivernetwork model. The validity of the model was checked with the observed water and sediment data of the TGR from June 2003 to December 2009. Good agreement between the calculated results and the observed data indicated  this model could be used to simulate the flow and sediment transport in the TGR area, and hence could be applied to the modeling and prediction for the optimal operation of the TGR in the future.
