| 摘 要： | 采用一维非恒定水流泥水流泥沙数学模型对黄河的“96．8”洪水泥沙输移特性进行了数值计算模拟，通过对洪水运动过程的水沙要素如断面的水位、数量、含沙量变化、洪水传播时间及河床冲淤等特性的分析表明，本一维非恒定泥沙数学模型在分析模拟洪水泥运动规律可靠性，为江河洪水预报提供一种重要的预测手段。

| Abstract: | Flood and sediment movement characteristic are simulated and analysed by one dimensional unsteady water and sediment numerical model.The main aspects include flood propagation process and sediment transport process,such as ,flood stage,flood propagation time ,flood discharge,sediment concentration,river bed erosion and deposition quantity and bed deformation etc,the analysis of these procces indicates that the simulate results are well in accordance with those related field data.It is also make known that the one dimensional numerical model is able to simulated flood and sediment movement.A efficiency method is provided with Yellow River channel flood and sediment forecast. |
