In this paper, analysis of bursting events was performed based on fluctuating velocity in three dimensions inside the vegetated compound channel. The trees were cultivated on the flood plain at different distances from the main channelflood plains boundary. The three dimensional flow velocities was measured using Acoustic Doppler Velocity meter. From the result of this study, it was found that the contribution probabilities of bursting event in region 2,4,6,8 are responsible for sediment erosion. Also in test which trees are cultivated at d=2cm from the edge of flood plain, is less than other tests, thus cultivating the trees at this distance from the edge of the floodplain is suitable for protecting this region.
