Abstract

The Soil Loss estimation for Water erosion process is very important in the prediction of environmental effects. In this work will be analized water erosion risk, potential and present; with a quantitative evaluation based on application of the Universal Soil Loss Equation crossing each parameter (litology, precipitation, slopes....). It will make a cartographic analysis by means of Geographic Information System (GIS), with generation of data base necesary in territorial planification. In the same way, cartography of erosion risk estimation, will be contrasted and applied to the study area for space-temporal distribution technics. This knowledge allow us the management and distribution of the humnan activities; and establish preventive and corrective actuations.

Key words: Universal Soil Loss Equation, GIS, cartography of erosion risk.
