This paper presents a measuring method suitable for a spot flow gauging in natural streamflows. It is based on the measurement of a tracer concentration (usually common table salt). The method enables accurate flow measurement without determining the cross-section area. The only condition that has to be fulfilled is the uniform mixing of a tracer across the downstream measurement section. The paper describes theoretical basis and a procedure for tracer concentration measuring. The results of the method implementation are presented as well as the tutorial carried out by the students of the Civil Engineering Faculty in Belgrade, Serbia. Finally, suitability of the method in different flow conditions is commented.
