Abstract
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 (EkIm) and the product of rainfall kinetic energy and AIm (EkAIm). 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 (EkIm) has a higher efficiency of predicting soil loss in the region and thus this can be used to estimate soil loss in southeastern Nigeria.
