To grasp the behavior of fine grain sand is important in order to elucidate the process of expanding vegetation growth area in gravel bed rivers. However, the sedimentation process of suspended load especially in steep gravel bed rivers has not yet been sufficiently studied because of the small influence of fine grain sand on the shape of the river. In this study, we report the data of the pa1ticle size distribution change on the flood plains during an artificial flood in the Satsunai River, and carried out the experiments on the sedimentation process of suspended load at the flood plain and vegetation area in a steep channel. It was found that the vegetation effect to deposition of suspended sediment was limited, as the effect was shown only until reaching the dynamic equilibrium state in our experiments.
