At present,the main method for the measured of river flow is direct measurement base on hydrological station or ship.The above method is subject to ship navigation or hydrological conditions.This paper used the detection data from UHF（ultra high frequency） radar detection of Wuhan Yangtze River,and tried to establish a relationship between surface velocity and velocity distribution in section,and further estimated the section flow.At the end,the estimated results were compared with the real-time measured data,and then verified the feasibility of using UHF radar to measurement river flow.
