The effects of deforestation, climate change and human actions cause significant changes in the morphology of the basin because of increased flow and sediment transport. As a result, high rates of erosion have been observed. The present study was carried out in the Mala River Basin of Cañete Province (Lima, Peru). The morphological change of the Mala River basin is evident in the formation of islands and in the branching course it has adopted over the years due to erosion. The objective of this study was to analyse the morphological change resulting from soil loss during the period 1996-2016 for the Mala River Basin applying RUSLE and geo-spatial techniques. The parameters of RUSLE model require 5 factors (R, K, LS, C and P), which are obtained through geographic and rainfall information from the main agencies of the country. With the information obtained, erosion rates were calculated through a map algebra with the application of Arc-GIS software. According to results, the average soil loss is 248.44 t ha-1 year-1 in the Mala River Basin. In addition, the erosion map shows that 42.38% of the basin presents extremely severe erosion levels. The results can help in the implementation of soil management and conservation practices to reduce soil erosion in the Mala River basin.
