Em terrenos de rochas cristalinas onde predominam gnaisses e granitoides, a água subterrânea é considerada geralmente de boa qualidade devido à baixa solubilidade dos minerais silicáticos que compõem essas rochas. Porém, em longo prazo, o inte

The groundwater modeling in fractured media is extremely dependent on the geometry and arrangement of the fractures in these media, since such discontinuities become preferred flow paths, considering the differences in hydraulic conductivity and perm
