- Abstract
Soil erosion is one of the problems threatening the Algerian environment. In agriculture, soil erosion leads to the thinning of the topsoil under the effect of the natural erosive forces of water, or under the effect of agricultural activities. The present study focuses on analysis and mapping of the vulnerability to water erosion in Saf Saf watershed, Algeria, through the integration of RUSLE model with geographic information system (GIS). Various parameters are utilized such as the rainfall erosivity factor (R), soil erodibility factor (K), slope length - slope steepness factor (LS), crop management factor (C) and practice management factor (P). The results are organized into seven classes of different soil erosion rate values. They have revealed that eighty five percent of the study area is experiencing acceptable rate of soil erosion loss less or equal to 5 t ha-1 yr-1 with potential soil erosion of 3.29 t ha-1 yr-1. The high soil losses are favored by steep slopes and degraded vegetation cover, mainly located in northeast, northwest and south of the basin. The present study of risk assessment can contribute to understand the spatial pattern of soil erosion in order to use appropriate conservation practices for sustainable soil management.
