Combined use of 2D electrical resistivity and seismic refraction in hydrogeophysical exploration

The knowledge of the geometry and the physical properties characterizing the subsurface has been a challenge for groundwater exploitation. The relationship between lithological properties, electrical distribution and wave velocity was explored for this research as a means of detecting porous aquifer...
