| 摘 要： | 为使洪水演进中计算获得的枯燥的水文数据变得直观形象，进一步丰富洪水演进可视化手段，运用以一维水动力学为理论基础的MIKE11 HD模型对北江流域白石窑坝下至连江口段洪水演进进行了数值模拟，借助MIKE11 GIS的“纽带”作用，结合ArcGIS平台实现了洪水演进过程的动态可视化。结果表明模拟计算精度和可视化精度良好，反映出洪水在滞洪区和峡谷区演进过程中的不同演进特点。直观形象的洪水演进过程有利于决策者全面把握洪水进程，提高流域防洪决策能力。 |

| Abstract: | In order to make tedious hydrological data from flood routing calculation more visualization and enrich visualization means,by applying 1-D hydraulic theory based on Mike 11 HD model,the flood routing of Beijiang River from Baishiyao Dam to Lianjiangkou Reach is numerically simulated and dynamic visualization of flood routing process is realized on ArcGIS platform with the help of Mike11 GIS as a link.The result shows that the simulation and visualization is highly accurate and can reflect different flood routing characteristics in flood detention regions and canyon regions.Visualized flood routing process facilitates decision-maker to understand flood routing process and improve decision making ability of flood control. |
