| 中文摘要: |
| 介绍黄河下游宽浅河段汛期水沙运动仿真模型建立在二维不恒定流与不平衡输沙理论的基础上，采用无结构不规则网络，结合了有限差分法和有限体积法的优点，能较充分地反映滩区、生产堤与滩槽冲淤变化对洪水演进的显著影响，并具有实时动态图象显示和人机对话功能。 |
| 英文摘要: |
| Based on the theory of unsteady flow and non-equilibrium sediment transport, a 2-D simulation model of flood routing and sediment transport in the lower reach of the Yellow River has been developed. The model is built by non-structural irregular grids, combining with finite difference and finite volume methods, in which the significant influences of overbank storage, local leve and scouring (silting) in the process of flood propagation can be well considered. |
