Abstract
HEC-RAS is widely used in the analysis and calculation of river management engineering due to its simple operation interface,simple model setting,powerful ability to deal with complex rivers and river-related buildings,and accurate simulation results.Taking the Shuga Village section of Xiaohuangni River in Guizhou Province as an example,the HEC-RAS model is used to establish a one-dimensional constant flow model for the study area,and the multi-scheme analysis and calculation are carried out,which can provide decision-making reference for optimizing the layout of project management schemes.The results show that the HEC-RAS model is simple to simulate and has high precision of water surface line results,which can provide decision-making reference for the design and optimization of small and medium-sized river management scheme,and meet the precision requirements of small and medium-sized river management projects in mountainous areas of Guizhou.关键词
