摘要
本文介绍了一维非恒定泥沙数学模型的原理和计算方法，并且对于泥沙数学模型中的一些关键技术等问题进行了较详细的讨论。利用已建立的一维非恒定泥沙数学模型，对黄河小北干流１９８１年洪水资料进行了模拟计算，计算结果表明：黄河干流、渭河、北洛河计算水位、流量过程线与实测值符合良好，可用于黄河的洪水演进计算。
The principles and calculating method for mathematical model of unsteady sediment flows are introduced in the paper and issues of some key techniques of sediment mathematical models are discussed in detail. The flood recorded data of 1981 in the reach from Longmen to Tongguan in the Yellow River are used to calculated and simulated by using established one dimension mathematical model of unsteady sediment flows. The results demonstrate that the process simulation of water level and discharge coincides perfectly with the facts in the Wei River, the Beiluo River and the Yellow River and it can be applied for calculation of flood process in the Yellow River.
