     this paper presents the results of experimental study that was accomplished in a vortex settling chamber to observe the flow structures as well as hydraulic efficiency. a polar grid of data accusation was designed to trace the velocity characteristics of the flow. an adv three dimensional velocity measuring equipment was utilized. the experiments were conducted under three different discharges and three dimensional flow velocities were then measured. the results were analyzed by using velocity vectors and streamlines in the superimposed horizontal sections. the secondary currents were also detected in the radial sections of vortex chamber. it was found that flow structure of basin is highly dependent on entrance velocity. two types of clockwise and anticlockwise vortices and some sink points in combination with each other were observed in radial sections of chamber where their configurations and role were varied with flow discharge.
