%X in the context of the pampean plain occur degradative processes related to hidric superficial erosion that affect livestock farming activities. the present contribution aims to model the sediment emission in northest pampean with forestation watershed. the methodology used consist in applying a cuantitative cartographic model developed on geospatial bases with an informative geographic system, supported in the modified universal soil loss ecuation (musle). an analysis of statistic validation was performed with a rain microsimulator in the field, for a rain of 30 mm.h-1 of two years of return. the results are georeferenced maps of each musle factor, valorized by color-intensity, that reaches values of 33.77 mg of emitted sediments at the end of the watershed, with a correlation coefficient of 0.94 and an adjustment of nash-sutcliffe of 0.82. the cartographic model developed gives precise information of the musle components for a concrete rain event. the application of the rain microsimulator allowed obtaining real values of the sediment emission with a high level of adjustment. the sediment emission in the watershed was proved to be scarce or nule.
