Abstract: This paper presents a kind of way to revise flow velocity distribution acco rdding to plane twodimension river mathematical model,by which we can find a linear correlation equation about U"_m/U_m and h_i/h from the regulation engineering of Guang Yin Sands in Chang Jiang River. The revision value can be better identical with the model measured value than the model calculated value can.

Key words: river mathematical model, flow velocity distribution, revision

摘要： 笔者在河流平面准二维水流数学模型的基础上提出了一种流速分布计算的修正方法,结合三峡库区观音滩急流滩整治工程实例找到U"_m/U_m~h_i/h的线性相关方程,修正后的结果能与模型实测值较好符合.
