This work shows the results of the hydraulic conductivity from infiltration tests developed in the Vaçununga watershed, in the region of Luis Antônio, northeastern portion of the state of São Paulo. This basin is constituted of sandstones of Botucatu Formation (more than 90%) and Sandy residual unconsolidated materials (unconfined aquifer Botucatu) that were responsible for the selection of this watershed for this study. The soil properties and its hydraulic conductivity were obtained by laboratory and field tests (double ring). Results showed that the water movement is significantly affected by the land uses and management practices, although the region presents geological homogeneity.
