The Western Ghats (WG) of southern India represent a geomorphologically sensitive terrain where soil erosion and landslides constitute major geohazards. The Chittar sub-basin (CSB) of the Achankovil River Basin (ARB) was selected for investigation owing to its steep slopes, high-intensity rainfall, and increasing anthropogenic pressure, which together accentuate erosional processes. This study employs remote sensing and GIS techniques in conjunction with the Analytical Hierarchy Process (AHP) and the Revised Universal Soil Loss Equation (RUSLE) to quantify annual soil loss and delineate erosion susceptibility zones. High erosion affects 684.11 ha (24.8%) of the basin, whereas low erosion is observed across 780.03 ha (28.3%). Multicriteria evaluation indicates that vegetation cover (NDVI), rainfall, soil texture, soil depth, slope, aspect, and elevation exert the greatest influence on erosion susceptibility. Spatial analysis reveals that the western sector of the basin is most vulnerable, the central region exhibits moderate susceptibility, and the northwestern part remains comparatively stable. The results provide a process-based understanding of erosion dynamics in tropical high-relief basins and furnish a decision-support framework for prioritizing soil and water conservation strategies in the WG.
Soil erosion is one of the most critical forms of land degradation affecting Mediterranean environments, particularly in mountainous regions where steep slopes, intense rainfall, sparse vegetation cover, and fragile lithological formations accelerate soil loss processes. This study aims to assess the spatial distributi...

Soil erosion poses a significant environmental challenge, particularly in ravine-affected areas where high-intensity rainfall leads to substantial soil loss, resulting in declining soil fertility and the conversion of productive agricultural land into wasteland. The present study focuses on estimating the rate of soil...

Soil erosion within reservoir watersheds can degrade land resources and mobilise sediment through drainage networks, making spatial identification of erosion-prone areas important for watershed management. This study assessed the magnitude and spatial distribution of soil erosion in the Gubi Dam watershed, northeastern...

Soil erosion has become one of the most severe forms of land degradation in tropical mountain areas due to the combined effect of steep topography, high rainfall erosivity, and rapid land-use change. The island of Samosir in the Lake Toba catchment has experienced increasing pressure from agricultural expansion and for...

Soil erosion is a major form of land degradation with serious environmental and socioeconomic impacts, particularly on agricultural sustainability. Thus, soil erosion risk assessment is crucial to inform policymakers and support effective mitigation measures. This study assessed soil erosion by using primary and second...
