| 摘 要： | 在前期研究的基础上,依据黄河流域水沙变化特点,建立能够长时间反映河网上冲淤和水流携沙能力反馈调节规律的泥沙输移网络动力学模型.通过合理设值将黄河枯水期模型与丰水期模型进行连接,得到能够体现枯水、丰水周期更替的全周期模型.计算结果与河网上实测数据的比对,检验了模型的合理性,利用该模型可进一步研究黄河泥沙输移特点.

| Abstract: | Based on our previous studies,a dynamical model is proposed to simulate the characteristics of the sediment transport in river networks in a long time scale.The model is actually the smoother combination of the two models respectively for higher-water seasons and lower-water seasons via setting fit values of the model parameters.And the main spirit of the model rests in the self-adjustment mechanism between the erosion-sedimentation state and the sediment-carrying capability of fluid.The model is tested by ... |
