黄河高含沙洪水模型的相似条件

Model Similarity Conditions of Hyper-concentrated Flood of the Yellow River

高含沙洪水模型相似律的研究是一个十分重要的课题。通过试验和理论分析，从挟沙水流运动及泥沙运动等方面研究了高含沙洪水模型的相似律，并就模型沙的选择及含沙量比尺的确定等问题进行了探讨。所提出的模型相似律得到了黄河高含沙洪水的验证。

Study of model similarity laws of hyper-concentrated flood has drawn close attentions from sedimentation researchers.Through experiment and theoretical analysis, model similarity laws ofhyper-concentrated flood were researched from the aspects of now motion and sediment transport.The selection of model sand and the determination of sediment concentration scale were alsoinvestigated. The propsed similarity laws were examined using measurements from hyper-concentrated flood of the Yellow River.
