摘要: 应用HEC-RAS和MIKE11模型，对成都市锦江流域的南河和磨底河进行了模拟分析。结果表明：同一模型不同计算方法时，恒定流和非恒定流计算结果差值较小；不同模型同一计算方法时，计算差值较大；在同一小流量下，HEC-RAS计算的磨底河水位比MIKE11的高；在同一大流量下，HEC-RAS计算的南河水位比MIKE11的低。非恒定流在模拟水流运动状态时，计算结果相对更加精准；建议锦江干流如府河、南河选用MIKE11计算水位，锦江支流如磨底河、浣花溪、沙河、桃花江等选用HEC-RAS计算水位。
Abstract: In this paper, HEC-RAS and MIKE11 models are used to calculate the water surface line of the Nanhe and Modihe Rivers in Jinjiang basin. The results show as follows: Using the same model with different methods, the difference between constant flow and unsteady flow is small; Using different model with the same method, the difference is large; At the same low flow rate, the water surface line of Modihe River calculated by HEC-RAS is higher than MIKE11; At the same high flow rate, the water surface line of Nanhe River calculated by HEC-RAS is lower than MIKE11; The results of unsteady flow are more accurate simulating the flow movement. Calculating the water surface line of Jinjiang main stream, MIKE11 model is recommended; Calculating the water surface line of other tributaries like Modihe, Huanhuaxi, Shahe, and Taohuajiang Rivers, HEC-RAS model is recommended.
