APLICAÇÃO DE MÉTODOS GEOELÉTRICOS PARA MONITORAMENTO DA BARRAGEM DE CONCRETO DA UHE GOV. JOSÉ RICHA

Abstract

The application of Geophysics to monitor the concrete body of the Salto Caxias dam had the main objective of developing a methodology complementary to the existing monitoring program. More specifically, the SP (Self Potential) method was used to map the preferential water pathways, while resistivity had a complementary role, providing information on the saturation degree (water content) in the dam body. The gradient was chosen as the electrode array best suited for mapping resistivity lateral variation in such a high concrete-electrode contact resistance medium.
