Abstract. The great incidence of on soil degradation makes interesting to measure its effects and to predict losses under the circumstances. At present, introduction of digital cartographic representation thecnics demands a review of traditional methods and the most complicated estimates or calculation in erosion models is the topographic factor LS. This report is a comparative study of a few usual methodologies for the determination of this factor. All of which use the same equations of the USLE method, the most used tool in such studies, but with different procedure in the accessories factors calculation.

Key words: LS factor, comparative study, estimate erosion models
