Therefore, it is necessary to quantify the comprehensive effects of vegetation restoration on soil erodibility
on steep gully slopes using multiple indicators.
With respect to the issue of how different sizes of initial cracks affect the barrier behaviours against eroding, the material erodibility
and the water velocity inside the mass should be considered concurrently.
The land's sensitivity to erosion is called soil erodibility

Finally, for potential soil erosion risk map overlay analysis is performed on erodibility
, erosivity and slope which is classified into low (0-5 index), moderate (5-11 index) and high (above 11 index) erosion risk areas.
This result suggests that the application of AZ improved the erodibility
of sodic soil, a finding which is consistent with the increase in MWD of the soil shown in Table 2.
For example, recent lab-scale JET tests on a silty sand soil and a silty clay soil showed that both soil compaction and water content have a significant impact on erodibility
. While higher compaction increased erosion resistance, soil texture and water content at the time of compaction affected resistance as much--or more.

Dry aggregate stability, a measure of the erodibility
of the surface by wind, was assessed using the method described by Leys et al.
