摘要：The study was focused on the alluvial fans formed in the bottom of the Bystra river valley. A detailed analysis offour fans allowed to distinguish several phases of gully erosion related to human activity. The gullies started to develop in theNeolithis times, the subsequent phases of gully erosion could be dated to: Bronze Age, Middle Ages. In modern times, mostof the sediments have been retained within the extensive gully systems.
