Prospecção Geoelétrica em Aqüíferos Fissurais, Estudo de Caso em São José do Ubá<br>(RJ)

In the crystalline system groundwater circulate through fractures and fissures. Geophysical methods are commonly used to investigate. In this paper we present the preliminary results of a geoelectrical survey conducted at Barro Branco sub basin, São José do Ubá county. We collected geoelectrical data at 3 profiles. Data were processed and interpreted with a 1D inversion scheme. Two main aquifer system were identified: sedimentary and cristalline.
