Abstract
This study aimed to prepare a map of the danger of water erosion in Al THAWRA basin dam in Lattakia during 2018 using Corine model, followed by measuring the variant of Soil erosin susceptibility through estimating soil texture, depth and stoniness percent. After that, the potential erosion risk map was prepared by the multiplication of soil susceptibility to erode map, slop map, and rainfall erosivity index value using GIS technique. As for the cover land map, it was prepared and classified into two classes according to protection degree. Therefore, the actual risk map was prepared through multiplication of potential risk and land cover map.The study showed that soil erosion susceptibility index was low in the northwestern part and was high in the western and northeastern part of the studied area with spaces (11.92 km2),( 16.66 km2) respectively , it also showed that the steep soils were concentrated in the southern and northern parts and some northeastern parts. Finally, the study indicates the importance of vegetation to reduce the area under high risk of erosion by 58.20 %.
Key words: Water erosion, CORINE Model, Geographic Information System (GIS), AL-Thawra dam basin
