Mike11与Hec-ras水动力模型洪水计算成果分析

An Analysis of Water Level Results Based on Mike11 and HEC-RAS Model

Mike11与HEC-RAS是时下较流行的水动力计算模型软件,两者基于不同计算原理导致计算成果存在差异。以乌溪江干流王村口镇段为例,根据实测地形成果与水文资料,建立乌溪江王村口镇段Mike11与HEC-RAS一维水动力模型,通过建模计算得到水位计算成果。与实地调查成果对比分析后得出2模型在实践应用中存在的差异。

Mike11 and HEC-RAS are popular hydrodynamic model in the area of flood level calculation,however based on different calculation formulas made them got different results.This paper is to study a case of flood level calculation along the Wuxi river(wangcunkou town section).Based on measured water level and flow data,two different hydrodynamic models of Wuxi river are established by using Mike11 and HEC-RAS.To compare the results of hydrodynamic models and the field survey results,and analysis the differences between Mike11 and HEC-RAS.
