Abstract Soil erosion is a significant worldwide threat, with far-reaching adverse effects on the environment. The general objective of this study to assess spatial average soil loss, identify high-risk areas, and visually represent variation loss from Melka-sedi catchment employing Revised Universal Loss Equation (RUSLE) geospatial modeling. RUSLE computes based five factors: rainfall erosivity, topography, cover management, erodibility, support management activities. distribution all factors final estimations were performed using ArcGIS workspace. results indicated that annual ranged 0 4,742 tons ha− 1 year− 1. area was categorized into subclasses severity zones: high, sub-high, moderate, sub-low, low. Most land, 209,561.24 hectares (77.25%), falls low category, while 36,093.65 (13.05%) are classified as sub-low erosion, 13,992.43 (5.15%) considered moderate 7,363.25 (2.71%) sub-high 4,249.98 (1.56%) high erosion. Overall, total throughout 1,098,931.5 tons. More than 4% land within requires urgent conservation It concluded found in catchment, it recommended prioritize erosion-affected areas apply practices achieve sustainable watershed catchment.

As the fertile topsoil is constantly washed away and agricultural production decreased, soil erosion a serious environmental issue that affects entire planet. All river basins experience changes in land use affect sediment dynamics, erodibility, hydrologic response. The main reason for faster rates frequently attributed to those alterations. In current study, Intensity of Erosion Outflow (IntErO) model was used estimate yield maximum outflow from three Cluj County, Transylvania, Romania. Because county hilly has significant issues, it essential have solid understanding how occurs basins. This will allow more precise planning conservation projects effective management severity processes.
