Soil Loss Assessment with RUSLE Model in GIS | Full Tutorial! (አማርኛ)

Master soil erosion prediction with this complete RUSLE model GIS tutorial! Learn the Revised Universal Soil Loss Equation step-by-step to calculate soil loss, map erosion risk, and conduct land degradation assessment. This guide is essential for environmental consultants, soil scientists, agricultural planners, and GIS students.

I'll show you how to prepare all five RUSLE factors: the Rainfall Erosivity (R), Soil Erodibility (K), Slope Length & Steepness (LS), Cover Management (C), and Support Practice (P). Using ArcGIS Pro or QGIS, we'll process DEM data, soil maps, land use/land cover, and rainfall data to create a final annual soil loss map (in tons/hectare/year).
