The work aim is to study a possibility of the experimental studying of the particles dispersion in the flow over a rough lateral tilted bed in the laboratory channel. Numerically discovered character of the particles dispersion in the flow over rough bed is confirmed experimentally: the particles could deviate from the downstream direction on a distance, standard deviation of which is proportional to the square root of the distance passed by the particle along the downstream direction. It is revealed that the sensitivity of the experimental method is enough for the study of the influence of the lateral bed slope on the particle trajectory deviation from the downstream direction.
