摘　　要：以对某河流整治前后的水力计算为例,简述了一维数学模型在河道整治计算中的应用。通过分析计算该河流现状河道及整治后河道两种状况下的不同洪水频率(20 a一遇和50 a一遇)的沿程水面线及断面过流特征,据此对景观设计中原规划的20a一遇洪水岸边线进行了调整,提出了较为合理可行的河道整治方案。Taking the river hydraulic calculation before and after regulation as an example, the application of one-dimensioned mathematical model in river regulation is introduced. Through the analysis of the different flood frequency （once in 20 a and 50 a）, the along water surface line and section flow characteristics of the existing river course and regulated river course, the 20 a flood line is adjusted for the original landscape design, and comparatively reasonable regulation scheme forward. bank is put
