黄河河口段一维水流泥沙数学模型

One Dimensional Mathematical Model of Water and Sediment Routing in the Yellow River Mouth Reach

  • 摘要: 针对黄河河口段河道来水来沙特性和河道冲淤演变特点,综合考虑了断面上水沙分布和冲淤分布不均匀,阻力变化、河口三角洲淤积延伸等问题,建立了黄河利津以下河口段一维水流泥沙数学模型。用该模型对多年汛期和冬季河口段内水沙进行验证计算表明:计算结果与实测结果基本吻合。本模型可用来预测河口段内沿程不同时刻水位、含沙量及河床冲淤的变化过程。

     

    Abstract: According to the characteristics of coming water and sediment,evolution of erosion and deposition of channel in the Yellow River mouth reach,the onedimensional mathematical model of water and sediment routing is developed from downstream Lijing station,considering ununiformity of flow and sediment in cross section,flow friction,extension of river mouth delta.The model is used to compute flow and sediment transport and river channel.The results agreed with the field data.The model can be used to predict the water level,sediment concentration,erosion and deposition in the Yellow River mouth reach.
