Summary:

The Krzczonówka stream is left tributary of the Raba River. In 2014, during the period from April to September, the project related to the lowering of the existing debris dam was carried out. Heavy rainfall resulting in high flows occurred shortly after the start of work. In effect, large amount of debris was moved from the reach located upstream of debris dam to the reach downstream of it. This work aims to present the influence of flood discharges on the morphology of the stream channel under conditions of high sediment supply. Observations on the changing conditions of water flow and sediment transport will also be presented
