abstract = "Soil erosion is currently one of the main concerns in agriculture,
water resources, soil management and natural hazards studies,
mainly due to its economic, environmental and human impacts. This
concern is accentuated in developing countries where the
hydrological monitoring and proper soil surveys are scarce.
Therefore, the use of indirect estimates of soil loss by means of
empirical equations stands out. In this context, the present study
proposed the assessment of the Revised Universal Soil Loss
Equation (RUSLE) with the aid of Geographical Information Systems
(GIS) and remote sensing for two agricultural watersheds in
southern Rio Grande do Sul - Brazil. Among all RUSLE factors, LS
showed the dosest patterns to the local when compared to the total
annual soil loss, thus being a good indicator t of risk areas. The
total annual soil loss varied from 0 to more than 100 t ha(-1)
yr(-1), with the vast majority (about 65% of the total area)
classified from slight to moderate rates of soil loss. The results
estimated according to RUSLE indicated that over 10% of the study
area presented very high to extremely high soil loss rates, thus
requiring immediate soil conservation practices. The present study
stands out as an important scientific and technical support for
practitioners and decision-makers, being probably the first of its
nature applied to extreme southern Brazil.",
