Erosion risk
tr_erosion_risk
What it does
Soil loss with the RUSLE form (A = R K LS C P) and its LS factor from the flow field.
Like No direct tool (RUSLE workflow in Raster Calculator) in ArcGIS Pro and SAGA LS Factor + Raster calculator in QGIS. Run by the product's terrain engine on 30 m cells from Copernicus DEM GLO-30 (full resolution): 740 x 930 = 688,200 cells; no model was called.
Erosion risk
Erosion (RUSLE form): mean soil loss 9.93 t/ha/yr; 27.9% of the ground is high or very high.

Notes
- DEM: Copernicus DEM GLO-30 (open data; cached). Copernicus DEM GLO-30: produced using Copernicus WorldDEM-30 (c) DLR e.V. 2010-2014 and (c) Airbus Defence and Space GmbH 2014-2018 provided under COPERNICUS by the European Union and ESA
- the grid (30 m) is finer than the DEM (30.9 m): values between DEM samples are interpolated
- R, K, C and P are uniform illustrative defaults: set them for the place
