ArcView GIS耦合HEC-RAS模型的应用研究

Application Research of ArcView GIS Coupled with HEC-RAS Model

以金盆水库为例,利用ArcViewGIS耦合HEC-RAS模型模拟了该水库在校核洪水情况下(P=0.05%),水库下游区域的洪水演进过程,计算洪水淹没范围并成图,并对模拟结果进行了分析.

Taking Jinpen reservior as an example, in the case of an extraordinary flood,downstream flood routing process has been simulated by using ArcView GIS coupled with HEC-RAS model. Flood undulation area has been calculated, then the results have been analyzed.
