Abstract:
This paper presents the methodological procedures used to identify potential sediment production
areas in the micro-basin sub-basinTietê/Cabeceira of São Paulo State. We generated several
information layers of the factors involved in erosion processes using the Geographic Information
System (GIS). The intersection of these layers enabled the development of cartographic products,
aiming at selecting potential sediment production areas. This micro-basin is composed by areas
with medium and high susceptibility to the erosion processes occurrence. Concerning the potential
sediment production, 80% in area is composed bylow and medium potential sediment production.
