应用 DEM 数字高程模型插值技术，快速获取计算区域的地形数据，其后基于 EFDC 模型的建模及水动力计算分析模块，建立了蓄滞洪区洪水演进模型，并借助于 ARCGIS 的展示功能，实现了结果的可视化。以漳卫河流域的大名蓄滞洪区作为实例，仿真模拟了1962年7月的一场洪水，在该蓄滞洪区的演进过程中，设计了三种不同的泄洪方案进行对比分析。结果表明，应用 EFDC 可以较好地模拟洪水演进的规律，为分蓄洪区防洪决策与抢险提供参考。

Digital Elevat ion Model( DEM) interpolat ion techniques can help achieve the area terrain data rapidly. The hydrody-namic modeling and computat ional analysis module in EFDC model w ere used to establish the flood routing model, and model results can be visualized w ith the help of ARCGIS display functions. In this paper, the flood routing in the Daming flood detention basin of the Zhangwei River was simulated based on the flood on July 1962, and the model results based on three different designed flood-releasing schemes w ere compared and analyzed. The results showed that the EFDC model performs well to simulate the evolution law of the flood, w hich can provide valuable references for the flood control decision-making in the flood detention basin.
