Limitations of USLE

• USLE is not calibrated to estimate gully and stream channel erosion nor does identify areas susceptible to landslides;
• It doesn’t identify areas of sediment deposition;
• Was not designed for use in tropical region.
• The USLE only predicts sheet and rill erosion.
• The “soil loss” as calculated by the USLE may refer to soil either removed from the field or simply soil relocated within the same field
• The calculated “soil loss” does not necessarily mean that this amount of sediment will enter a stream.
