HEC-RAS模型原理及应用研究进展

A REVIEW OF THE PRINCIPLE AND APPLICATION OF HEC-RAS MODEL

介绍了HEC-RAS模型地基本原理,总结了HEC-RAS相关文献逐年发表数量,从水动力模块、水质模块、与其他模型/软件地联合应用3个方面介绍了HEC-RAS模型的应用现状,特别比较了与MIKE11等模型在水面线推求地差异,对比了HEC-RAS和其他水质模型在水质模拟方面的差异。以期为HEC-RAS模型的初学者提供参考,同时也为水环境模拟中的模型工具选择选择提供依据。

Model is a commonly used tool for surface water environment assessment and prediction.HEC-RAS model is a hydrodynamic water quality model that has been widely used in recent years.This paper introduces the basic principle of HEC-RAS model,summarizes the number of HEC-RAS related literature published year by year,introduces the application status of HEC-RAS model from three aspects:hydrodynamic module,water quality module,and joint application with other models/software,especially compares the difference between HEC-RAS model and MIKE11 model in water surface profile estimation,and compares HEC-RAS and other water quality models in water quality simulation.It is expected to provide reference for beginners of HEC-RAS model,and also provide basis for model selection in water environment simulation.
