The erodibility factor K (defined by the Universal soil Loss
Equation) is a measure of the soil's susceptibility to erosion.
The relative erodibility of 3 Great Soil Groups, namely, Reddish
Brown Latosolic Soils, Immature Brown Loams Soils, and Red Yellow
Podzolic Soils, in the Victoria catchment area, in Sri Lanka, was
estimated using a rainfall simulator technique on micro plots.
The relative erodibility of

The rate of run-off of
IBL > RBL > RYP
IBL) RBL>RYP
Hence, IBL, the most predominant soil in the area, was the most
susceptible to erosion hazards.
A slight grass cover on the plots, drastically reduced the
erosion hazard and the effect of grass -cov-er --on RBL> IBL > RYP.
Clay had a more stabilizing effect in protecting the soils against
erosion.
