Abstract
The Ground Penetrating Radar (G.P.R.) method was applied for the detection of shallow karstic phenomena along the scheduled course of the new Athens-Thessaloniki motorway at the area of the lake Yliki. Calibration transects were performed over known cavities in order to establish the proper processing sequence and also to set an estimate for the velocity of the electromagnetic wave in the Limestone of the area. Reflection patterns were recognized which were caused by the known cavities. Thus, similar patterns observed at the mass of the G.P.R. sections were attributed to possible concealed karstic phenomena. Limited drilling which followed our investigations confirmed the truth of t he assumption.
