Soil erosion poses a significant environmental challenge in semiarid regions, as illustrated by the Cheliff Basin in Algeria. This study utilizes the Revised Universal Soil Loss Equation (RUSLE) model to explore the intricate interactions among rainfall, soil type, topography, and land use/land cover, leveraging satellite data to evaluate their effects on erosion rates. The analysis uncovers a heterogeneous erosion pattern, with intensified rates near water bodies. A notable area of concern is a 13.83 km2 zone with moderate roughness, constituting 31% of the basin, which requires immediate and targeted intervention. The correlation between diminishing water surfaces and increasing aridity underscores a complex relationship between water loss and erosion. These findings highlight the pressing need for sustainable land-use planning and focused soil conservation efforts to address erosion challenges. This research offers valuable insights for shaping effective environmental policies and promoting sustainable land management practices.
