Soil erosion is a major issue. Erosion is degrading the quality and standard of soil across the globe continuously. It emerges as significant socio economic and environmental threat throughout the world. This paper describes comprehensive summary on estimation of soil erosion carried by past researchers using different models. This study found that soil loss prediction by using different models gives different accuracy of it. The area with higher slope range seems to be more prone to erosion compare to lower slope range. The utilization of different technique to estimate the mean annual soil loss is an effective tool in mapping the spatial distribution of entire watershed.
