This paper is concerned with the 3D trajectory of particle released from the crest of modeled river bed configuration. The trajectory of particle was visualized by using of two CCD video cameras. One of them is placed on the flume and the other is placed at the flume side.
After the correction for particle coordinate, the particle trajectory was shown by means of wire frame method, and moreover the 3D trajectory was indicated realistically by means of ray tracing method.
The results of this paper are as follows : A ccording to increasing discharge, trajectory of particle showed a complex motion such as abruptly upward or swirly motion.
