Abstract: To combat erosion, there is need for adequate examination of soils and factors of erosion. The study of Erosivity is vital for effective soil conservational planning and agricultural activities in Enugu State of Nigeria of West Africa, and other parts of the world. In this study, rainfall amount and duration were obtained and used in the determination of rainfall intensities in Enugu regions. These rainfall records were used in calculating the three erosivity indices namely; the maximum 30-minute intensity, kinetic energy greater than 25, and peak storm intensity. With the aid of the above data, erosivity of Enugu was uncovered. This was achieved by taking the average of the calculated years. This Erosivity value can be used in modeling a general soil loss equation for all soil types in Enugu. This general soil loss equation can be used to predict erosion in Enugu region. Also, from the force impact of rain capable of causing erosion, erosive rain were separated from non erosive rain using the method based upon the concept that there is a threshold value of intensity at which rain starts to be erosive. With this insight, one can also predict future erosive rain and non erosive rain using the weather forecast data. With the knowledge of these predictions, erosion prevention technique may be applied in areas of possible future occurrence rather than remediating soil after erosion hazard.
