摘要:Study of sediments at gullies mouths conducted in the Suwałki Lakeland (NE Poland) showed that fan sedimentsare significantly diversified. The changes of sediment type could be linked to forest clearance and farmland expansion.Dating and lithological properties of fan sediments allowed to determine the stages of gully erosion. The research also includedstudies of sediments accumulated within last 200 years in 6 small gully catchments of different degree of cultivation.Supply of the sediments derived from soil erosion to the gully fans was very limited in catchments where only 15% of the landwas cultivated. This process was intensively active in catchments where cultivated land occupied 77% of the area.
