Gestión integrada de recursos hídricos: Erosividad de la precipitación. Caso de estudio de la cuenca del río Zamora

Abstract

Abstract: This research aims to evaluate the impact of erosion caused by precipitation in the Zamora River basin, located in the Zamora Valley, Loja Province, in southern Ecuador. To this end, rainfall intensity and frequency data were used at different time scales. The proposed methodology includes a comparative analysis of different techniques for estimating soil erosion caused by rainfall intensity. In this study, calculations were performed using pluviographic data obtained from the Época and Jipiro meteorological stations. The analysis was developed using the Revised Universal Soil Loss Equation (RUSLE), with emphasis on the R factor, as well as the Modified Fournier Index (MFI), a representative indicator of rainfall erosivity. The results demonstrate the correlation between both methods, which supports their combined use and encourages their application in future research.
