Geophysical methods have been a part of the construction engineering toolbox for decades (e.g., seismic methods for foundation design; Peck et al., 1974) and, although adoption of the technology over this time has been slow, their use on major infrastructure projects has now become routine. According to [8], [9], electrical resistivity survey and seismic method are geophysical methods used in civil engineering concerns.Station 32 In resistivity method, ABEM Terrameter SAS 4000 was used for data acquisition. Archaeologists can be greatly helped in setting his digging priorities if geophysical methods can be used ahead of time.
