Abstract

After the discovery that fossil fuels are not renewable over the human time scale, the worldwide search for renewable and cleaner energy sources has expanded, benefiting the Brazilian cane sugar production. Accordingly, the perspective is for growth in this sector. In this scenario, the present study is inserted, in which the aim is to investigate the erosion dynamics, mainly caused by intense rainfall in a watershed covered by sugar cane, establishing relationships between transported soil volume during rainfall, the concentrations of suspended and sedimented solids, agricultural practices and the function exerced by riparian forests. For this, will be determined the volume, the particle size, the teor of carbon and nitrogen, 15N, 13C, 14C and lignin phenols in total suspended and sedimented solids of areas covered by cane, by riparian vegetation and watercourse. Additionally, we will determine the intensity of rainfall. The study will be conducted in Corumbataí river basin, located in the central-east of the state of São Paulo, which is widely exploited by the activity sugarcane. In this basin was selected one microbasin covered by sugar cane for the study.
