Erosion rate in the Alps

The Revised Universal Soil Loss Equation (RUSLE) was applied to the whole alpine area. The model calculates annual soil loss (t ha-1 yr-1) based on Rainfall Erosivity Factor (MJ mm ha-1 h-1 yr, Soil Erodibility Factor (t ha h ha-1 MJ-1 mm-1, Slope length Factor (dimensionless), Slope Factor (dimensionless), Cover Management Factor (dimensionless), Human Practices aimed at erosion control. The output grid cell is 100
