The current focus of research about the environment has been on soil and water and conservation of natural resources, aiming at reducing anthropic impacts, in order to make their use sustainable. In this context, the basin has been used as a geographic region in hydrological studies, being considered as an environmental unit, which makes it possible to deal with the components and dynamics of the interrelationships necessary for environmental planning and management. The aim of this research was to estimate soil loss by water erosion using the Universal Soil Loss Equation (USLE) for Santa Rita basin, localized in the Arroio Moreira Fragata Basin, in Pelotas, RS. In most of the basin, soil losses of less than 10 Mg ha-1, considered as small, but in some areas it losses were 50 Mg ha-1, being classified as moderate to medium. Santa Rita basin can be considered low susceptibility to water erosion.
