Abstract: Non-destructive seismic reflection and resistivity imaging techniques have been successfully applied at Mandoudi, Euboea aiming to contribute with essential information for the simulation of the Lakka karst aquifer. A seismic reflection and refraction survey was carried out to determine the active thickness of the karst aquifer. Electrical tomography indicated that there is no hydraulic communication between Lakka aquifer and the Nileas River. The resulting geophysical models were useful for building a conceptual geological/hydrogeological model of the aquifer. This model also contributed by guiding a drilling program for the irrigation of the plain area in the north and east of Mandoudi.
