Abstract: Measurements of mean velocities and Reynolds stress in steady open-channel flow were carried out over a smooth bed. Using Acoustic Doppler Velocimeter (ADV) and Constant Temperature Anemometry (CTA), the instantaneous velocities were obtained. In this study, both velocity and Reynolds stress profiles were analyzed. The effect of the instrument on these profiles were also examined by means of a comparison, over a longitudinal section of the channel.The flow patterns are investigated at five different lateral sections.The experimental data show that,both stream-wise velocity and Reynolds stress distribution deviated from the observed ADV results compared to CTA.In the regions of (𝑧/𝐻≤0.2𝑎𝑛𝑑𝑧/𝐻>0.7),more variation in velocity. The Reynolds stress distribution from CTA at all measured sections was similar, which differentiate the measured ADV data.
