英文摘要	Loss and degradation of soil due to water erosion is among the most well-known types of worldwide land disturbance, specifically in arid and semi-arid areas. The complexity of the erosion study breaks the problem of comprehensively understanding all the factors that significantly affect this process. Water erosion is triggered when the retention capacity of soils is less than the amount of rainfall, which promotes surface runoff. The latter, under unfavourable environmental conditions, becomes the principal cause of water erosion. This study aims to use the geographic information system and remote sensing techniques to assesses and evaluate the soil losses under semi-arid climate conditions using the revised universal soil loss equation model (RUSLE) in comparison to a new approach based on surface erosive runoff (RUSLErunoff). The study zone is Wadi Soubella Watershed, NE of Algeria which, extends on 185 km(2) in the East part of the Hodna basin. The results show that the Wadi Soubella Watershed is affected by low to moderate and rarely by high soil losses, with various rates between 0 to 100 t km(-2) year(-1) and rarely reaching 300 t km(-2) year(-1). The most affected areas with intense erosion pressure occur in the foothills of the mountains (Djbel Mouanich, Ras Tenndar, Kef el Assa and Djebel Soubella) and the bare land degraded areas. The relationship analysis (slope-erosion) using the RUSLErunoff model showed that soils subject to steep slopes and high vegetation cover (forest) are more vulnerable than other land-use classes, showing the effect of the surface erosive runoff. The root mean square error between the observed values according to the two models show that low slope class and the steep slope class show that RMSE is higher than the RMSE in mid-class slope with (54 t km(-2) year(-1) and 130 t km(-2) year(-1)) and (13.54 t km(-2) year(-1) and 14.47 km(-2) year(-1)), respectively. The comparison between the two models showed a satisfactory power regression with R-2 = 0.49 and r = 0.7. In deduction, the relationship from the integration of surface erosive runoff as a factor for the soil loss estimation in the Wadi Soubella Watershed is exponential. The protective behaviour of forest cover is shown more clearly by the RUSLErunoff model than the RUSLE model.
