I was reading through a report that gave a recommendation that currently soil erodibility can be estimated using the soil family, soil group and soil texture. This is giving me confusion because the formula which is being recommended is exponential and contradicts which general literature
Where F is the soil erodibility ratings and E is Rainfall Energy
K = 2.8 x 10-6 x M1.14 (12-a) + 0.043 (b-2) + 0.033 (c-3)
Please provide clarification
Thanks in advance
