Abordagem Geofísica Em Terrenos Sedimentares Costeiros Baseada Em Técnicas De Eletrorresistividade, Eletromagnético Indutivo E Inversões E Sua Aplicação À Prospecção De Água Subterrânea (Região De Cascavel – Estado Do Ceará)

Resistivity methods (lateral profile and vertical soundings) were integrated with eletromagnetic data derived from EM-34. Also, the combined data inversion (ER+EM) were carry out showing the potentiality of the integrated geophysical techniques to the study of groundwater in coastal regions of the State of Ceará, NE Brazil. A joint interpretation of the above techniques, show that the crystalline structure under the sedimentary cover were the most important zone to the water contribution in several wells in Cascavel region. Several anomalies related to low conductivity zones represent good places for groundwater prospecting.
