AB  - Rainfall data from 3 representative locations in southeastern Nigeria were used to evaluate and establish 3 rainfall erosivity: The product of rainfall amount and the maximum 7.5 min intensity (Aim); the product of rainfall kinetic energy and maximum 7.5  min intensity (E<SUB>k</SUB>I<SUB>m</SUB>) and the product of rainfall kinetic energy and AI<SUB>m</SUB> (E<SUB>k</SUB>AI<SUB>m</SUB>). These indices were applied in the Universal Soil Loss Equation (USLE), to estimate soil loss in the 3 locations. The predicted soil losses were compared with the measured soil losses. The result of the study shows that (E<SUB>k</SUB>I<SUB>m</SUB>) has a higher efficiency of predicting soil loss in the region and thus this can be used to estimate soil loss in southeastern Nigeria.
