Abstract: Experimental research is reported on flow in a curved open channel, with emphasis on the outer bank region. Simultaneous measurements of the three instantaneous velocity components were made in one section, from which the time-averaged velocity components, v (v s, v n, v z), were derived. This paper is concerned mainly with the timeaveraged secondary motion, (v n, v z), whose measurements on a fine grid and with high precision resulted in a detailed presentation of the flow pattern and permitted to calculate accurately the downstream vorticity component, Sω. The patterns of secondary motion, (v n, v z), downstream vorticity, ω s, and downstream velocity, v (v s, are presented.
