Land displacement processes on the slope can be differentiated after the types of movements in creep, landslide or mass movement, earth flow, rock fall, rock topple. By combination of two or more types results a complex displacement. Factors that determine degradation by displacement are the relief, vegetation, climate, rock and parent material, and plus the influences of erosion, earthquakes. The studied land is situated in the Făget Hills and near the river Bega, in the northeastern part of Timi; county. For the cadastral territory Margina has been made a pedological report at large scale of 1:10.000 for 5029,46 ha. There are 77 soil mapping units. In the southern territories of river Bega (Coșevița) there are Pleistocene and accumulation of alluvia, wherein prevail argillaceous marl. The soil mapping units established for the whole territory are: Luvisols; Cambisols; Gleysols; Stagnosols; Leptosols; Regosols; Fluvisols; Anthrosols. The total area affected of landslide is 194.28 ha, which represents 3.86 % from the total villige’s territory. The soil profiles situated in the territory with landslides are 10, 11, 12 and 38, namely: Stagnic Luvisols, Anthrosols, eroded, Luvic Stagnosols, stagnic Luvisols. A general characteristic for all soil profiles situated on the landslide field is the interference between the horizons. The bedding rocks are predominantly clayey (argillaceous marl) in which the expandable minerals are ~ 80%, with strong shrinkage – swelling phenomena. Corresponding to the recommended measures established by the studies can be constructed concrete plates, supportwalls, elements of ferroconcrete or soil conservation by afforestation. The land improvement must be realized within a single project for the whole torrential watershed.
