- Abstract
The Upper Paraíba River basin is strategic for the management of water resources in the Paraíba State. Recently the basin began to receive waters of the transposition of the São Francisco River, generating the perenization of the main river. This water descends the course of the Paraíba river, passing until reaching the Boqueirão Dam, the main water reservoir of the region. However, the study of soil losses in the basin is fundamental to analyze the runoff-erosion behavior in this basin. In this sense, the present study aims to evaluate soil losses in the basin, determining the most critical factors and areas. Universal Soil Loss Equation was used from map algebra. The results showed estimates of low to moderate soil loss predominantly (0-120 t/ha.year). The estimated soil loss rates are compatible with the literature for semi-arid environments. The land cover factor was considered the most important in the calculation of the USLE for the basin.
