From 96 variables, 15 were significantly correlated to soil erodibility.

Soil erodibility factor ranged from 0.033 to 0.077 in the watershed.

Subsequently, real erodibility of soil by wind was determined at these three areas.

Microrelief characteristics control erodibility and erosivity, which will significantlyinfluence wind erosion and dust emission.

Lastly, the system incorporates a landscape factor related to land erodibility and constraints to management.

Soil mineralogy seems to be the key factor regulating soil erodibility variation in the area.

The results showed variations in erodibility and in critical shear stress values of the roads.

The erodibility can be estimated by aggregate stability indices based on sonication analysis.

Based on these data, correlated with the soil losses, the soil erodibility could becomputed.
