Abstract: Stone mattress is one of revetment structure installed in the river. This study validate the effects of soil constraint filter which is installed inside of stone mattress. Flood discharge condition was used in the fixed and movable bed hydraulic experiments. Slope and revetment river bed conditions also applicated to the hydraulic experiment model for the various flow conditions. In the movable experiment condition, existence of soil constraint filter were performed for analyzing the effectiveness of soil loss in the stone mattress. In the result, soil constraint filter installed condition shows the residual rate of soil increased more than that were not installed conditions. Constrained rate of soil in the slope and revetment bed conditions showed a dissimilar trend in the experiment at movable bed condition. It is considered that the soil loss in the stone mattress revetment influenced more on the high slope condition than on the supercritical flow with high froude number.
