Fundamentals & Data Preparation: Introduction to Soil Erosion: Processes, impacts, and modeling needs | USLE & RUSLE structure and applications | Data requirements & sources: SRTM DEM, SoilGrids, CHIRPS (CSV), Sentinel-2, Bhuvan LULC | DEM preprocessing, reprojection, and raster alignment in QGIS
R & K Factor Computation: Estimation of Rainfall Erosivity (R) using CSV datasets | Soil Erodibility (K) calculation | from texture, organic matter, and structure classes | Rasterization and standardization of input layers
LS & C Factor Computation: LS-Factor generation from DEM using SAGA GIS (slope, flow accumulation) | NDVI generation using Sentinel-2 via SNAP and SCP Plugin | Derivation of C-Factor using NDVI or classified LULC map
P Factor & Final Soil Loss Calculation: P-Factor estimation based on slope or land use practices | Soil Loss calculation using raster calculator: A = R × K × LS × C × P | Classification of erosion risk zones | Zonal statistics and map exports | Final discussion and use cases in watershed management
Web & Print Map Creation: Design professional printable maps and build interactive maps.
