摘　　要：HEC-RAS(River Analysis System)模型是由美国陆军工程师团开发的一款模型,利用该模型可以进行河网的一维水力学演进模拟.模型所需要的河网几何资料可以由HEC-GeoRAS生成.介绍了利用HEC-RAS进行河网洪水演进计算的原理与流程,以及利用HEC-GeoRAS构建河网几何资料的原理和流程.作为实例,利用HEC-RAS与HEC-GeoRAS对南四湖下级湖进行建模,并利用模型对次洪模拟,结果表明模型对于南四湖是适用的.HEC-RAS（River Analysis System）is developed by the U. S. Army Corps of Engineers, with which one-dimension flood routing calculations can be performed. Geometric data of river system needed by HEC-RAS can be created by HEC-GeoRAS. The principle and procedures of performing hydrologic calculations by HEC-RAS as well as principle and procedures of creating geometric data by HEC-GeoRAS, are introduced. For case study, HEC-RAS and HEC-GeoRAS are used to model the lower lake of Nansi lake; several floods are simulated by the model. The results show that the model is suitable for the Nansi lake.
