Abstract Based on the hydrological data of water discharge, suspended sediment concentration and water level from Sanhuhekou hydrological station of the Inner Mongolia reach of the Yellow River from July to October, 2012, the scouring effect of flood on the channel deposits has been studied. And the relationship between water discharge and vertical variation characteristic of the suspended sediment concentration and grain-size from August to October, 2012, has been analyzed in detail. The results are as follows: High peak and large flood volume, sharp rising and declining, long flood process duration and the fat of peak shape are the characters of this flood. The vertical variation character of grain-size during flood process indicates that sediment particle size smaller than 0.05 mm can be transported under the flood water discharge below 2 000 m3·s-1, and when the water discharge is at 2 000～2 400 m3·s-1, the largest sediment transport can occur in the river channel. But the flood has poorly scouring effect on the coarse sediment (grain-size larger than 0.05 mm).
