| 摘 要： | 三峡区间的数字流域水系模型采用基于格网型的数字高程模型坡面流模拟方法和处理"洼地"的最短流程法构建,并以新安江模型为基础建立具有诸多特点的三峡区间流域水文模型;以水动力学理论为基础建立考虑水利工程影响的河川型水库洪水演进模型,并实现这两者的有机耦合。在GIS平台上,将三峡区间流域水文模型、库区洪水演进模型和流域水系生成模型在底层集成,研制了功能先进和完善的三峡水库实时洪水预报系统。该系统已安装在三峡总公司梯级水库调度中心,投入试运行。

| Abstract: | A watershed drainage network generation model (WDNGM)is developed in the Three Gorges watershed on the basis of the hillslope flow modeling approach and the shortest flow course method for ‘filling sink',using the digital elevation model (DEM).The Xmanjiang model is improvedfor development of a watershed hydrological model characterizing the Three Cxmges watershed.Basedon the hydraulic dynamic theory,a flood routing model of the river channel pattern reservoir in the Three Cxmges,considering the water project operation influences,is established and fully coupled with the watershed hydrologic model.On the GIS platform,a real-time flood forecasting system is developed by integrating the watershed hydrological model,the flood routing model and the WDN GM in the Three Cprges watershed,which its functions are advanced and complete.This system has been installed and test operated by the reservoir control center of Three Gorges Company. |
