Use of ground penetrating radar (GPR) for coastal aquifer characterization in Garopaba/SC

The work analyzes the sedimentary deposits of the coastal aquifer of the locality of Limpa, Garopaba (SC), through geophysics and well data. A ground penetrating radar section (GPR) was acquired in an area adjacent to 4 wells located in thesouth of the municipality, provided by the water and sanitat...
