Ocena zagrożenia erozją wodną zlewni rzeki Bystrej z wykorzystaniem modelowania przestrzennego

The work included the production of an actual water erosion risk map for the area of Bystra watershed, basing on vector layers: potential water erosion risk and CORINE Land Cover 2000 as a source of land use information. The results show relative high share of actual erosion in avegare to highest intensities – 32.5% of Bystra catchment. Compared to potential water erosion, where the same grades cover 41.0% of watershed’s area, the erosion risk at high grades decreased only by 8.5%. Actually, according to the land use structure derived from CLC2000, around 9694 hectares undergo high water erosion intensity grades and needs erosion control measures.
