Abstract: The influence of the sediment concentration on abrasion was analyzed. A concept of sweeping abrasion was brought forward. The view point was put forward that the sweeping abrasion and the little-angle cutting abrasion will aggravate with the increasing of sediment concentration, but the abrasion of single particle will mitigate with the increasing of sediment concentration. Cavitation erosion will aggravate with the increasing of sediment concentration when sediment concentration is relatively low, but it will mitigate when sediment concentration is relatively high. The conclusion was put forward that critical sediment concentration sometime may not exist.
