Soil loss estimate in the cubatão do norte river hydrographic basin, northeast of santa catarina, Brazil
The main objective of this paper was to apply the Revised Universal Soil Loss Equation (RUSLE) through Geographical Information System (GIS) in the Cubatão do Norte watershed, in Joinville and Garuva municipalities of Santa Catarina State. The map of annual estimated soil loss by water erosion showed minimum erosion rates of 429.28, average of 854.61 and maximum of 1,579.49 t/ha/year. Soil loss due to water erosion in the Cubatão do Norte watershed can be considered low, since 97.58% of the basin area presented none or slight annual average soil loss, ranging from 0 to 10 t/ha/year.
