Popis: A longitudinal vertical cross-section of unsteady open channel flow was visualized by video camera. The 120 frames during 4 seconds in rising stage and the 120 frames during 4 seconds in falling stage were analyzed by cross-correlation method to obtain velocity vector distribution. The structure of large scale turbulence which drives longitudinal spiral motions were examined by using the obtained data.
