The dating and lithological features of the analysed gully fan sediments allow to determine of 4 stages of gully erosion. Based on thickness of the sediments and their age, the rate of accumulation can be calculated. Based on the Visher's granulometric curves and relations between sedimentological indexes were established source of gully erosion products. The stages of gully erosion were compared with archaeological and palynological data. The first stage (from 1500 BC to 3rd century AD) of the development of the gullies was probably determined by climatic factors, because erosion began at the bottoms of the dellies before forest clearance. In this period, the oldest sediments of alluvium type were deposited. The analysis of the values of mean grain size and d-5%, allowed to identify the source and mechanism of sediments transport. The first of gully erosion stage in the studied area was triggered by natural climatic changes linked to the humid periods of the late Holocene. The next stages are linked to both human and climatic influences.
