In Romania, in recent decades, many facilities to combat soil erosion have been abandoned, which leads to the amplification of the effects of this phenomenon, with repercussions on the environment. In this context, through this study, it is aimed to apply a spatial analysis model to identify areas susceptible to soil erosion, to establish the intensity of this phenomenon, but also to analyze its impact on the environment, at the level of the Crişul Alb basin. GIS technique and Universal Soil Loss Equation (USLE) were used. Through this equation, the following factors, participants /determinants of soil erosion were taken into account: climatic aggressiveness, land topography, soil characteristics, vegetation cover, land improvement measures. The soil erosion map at basin level, was classified into five classes, respectively areas with very low, low, moderate, high and very high susceptibility to soil erosion. The results show that 74% of the territory belongs to the class of susceptibility to very low erosion, and 4% with high and very high erosion rates, these being the main "hot spots" that must be taken into account in the development strategies of the hydrographic basin.
