MAPPING SOIL EROSION SUSCEPTIBILITY USING GIS TECHNIQUES WITHIN THE DANUBE FLOODPLAIN, THE CALAFAT - TURNU MAGURELE SECTOR (ROMANIA)

The Danube floodplain, the Calafat - Turnu Magurele sector, through its main features (topographic and climatic characteristics, land use and soil type) and human activities, constitutes an area exposed to soil erosion. The main objective of the present research is to map soil erosion susceptibility using the GIS techniques for the computation and representation of areas, which are exposed to soil erosion correlated with the field data for the validation. Analyzing the entire model, the relatively simple methodology, the database consistence, the comparability of the results with the existent soil erosion values at national and local scale, we can say that the model was applied with success in the studied area (areas and classes of water erosion susceptibility: very low, low, moderate, high - Ciupercenii Noi, Desa, Macesu de Jos, Grojdibodu, Orlea, very high Rast, Negoi, Catane, Bistret, Goicea; areas and classes of wind erosion susceptibility: very low, low, moderate - Ciupercenii Noi, Dabuleni, Ianca, high - Calafat, Poiana Mare, Desa, Goicea, Piscu Vechi, very high - Poiana Mare, Rast, Negoi, Bistret, Gighera, Orlea. The soil erosion susceptibility map can be useful for planning erosion control measures and for selecting suitable sites for runoff plot experiments.
