Erosive processes have been evaluated in a sector of the Skawa river characterized by high pliability to erosion (proportion between the bend radius and the river channel width equals on the average 6.5). Within two years, channel erosion caused by 6 freshets was investigated with flows Q within the range of probability of waters from 20% to 50%. Bank and bottom erosion as well as transportation of the bed material and material from falls of bank slopes were found to occur. Intensity of this transportation was calculated based on Bagnold's equation. The calculated value of transported bed load was comparable with that obtained from direct measurements. The effects of transportation were also reflected by changes of the grain size distributions after passage of a freshet wave. Bank erosion was the dominating process that changed the river channel shape. It was found that in the examined sector the retreat of the bank slope proceeded at the rate of 1.20 m/year.
