Summary:

The present paper contains results of researches carried out on the Slomka stream, which is very intensively erosive. A study reach is limited to the channel section being 367 meters in length, with local changes of the bed slope. It woe surveyed in detail and related to data on discharge, channel changes after floods and grain-size distribution of the bed material we have noted that river bank undercuts were dominant forms of bank erosion witch was the most important process for the channel bed modeling. The bed configurations of type chutes and pools were observed because of multiple roughness related to variation in stream power, shear stress, and grain-composition of the bed material. This parameters, longitudinal profiles, volume of eroded material, and intensity of sediment transport have been determined and calculated on the basis of the measuring results.
