KEY WORDS:

SUMMARY:

The modification of natural landscapes by anthropic activities is the main responsible for the deepening of erosion, negatively impacting the natural resources in a general way. In this context, it is necessary to know the processes that determine the hydrological balance to avoid erosion. Due to the complexity of a hydrographic basin and the necessity of making previsions, the development of mathematical models is essential to the decision making. These tools, when integrated into the System of Geographic Information (SGI), can couple the space-time shaping in a single quantitative structure. Among the existing models, the SWAT (Soil and Water Assessment Tool) software and model can integrate the SGI technics with hydric balance equations, becoming one of the most utilized models in the world with most different purposes. The objective of this work is to quantify the loss of soil in a hydrographical basin (Ribeirão do Feijão, in Brazilian southeast), utilizing the SWAT to predict the impact of the maneuver and using of the soil. The loss of sediment will be estimated and compared in two distinct times, the years of 2011 and 2019. Last will be rated witch areas of the basin of Ribeirão do Feijão that should be restored to reduce the production of sediment to values that don’t compromise the hydric courses. In this manner, the work will contribute to the orientation of the usage planning and basin occupation study, making possible the prevention of the impacts that occur negatively in the water and soil, compromising the ecosystems services.
