An area prone to landslide, threatening a small accumulation dam and a near-by landfill, was investigated by means of electrical resistivity. The variation of electrical parameters (electrical resistivity and chargeability factor) of soils and rocks is seldom used as a diagnostic tool in areas prone to mass movements. When the mentioned parameters are acquired using a multielectrode measuring system, the subsurface characterization is highly enhanced, considerably decreasing the number of invasive tests necessary ...

Geoelectrical contrasts generated between underground voids and the surrounding materials, their vertical or horizontal development, geometry and burial depth are key elements for voids detection when investigated by electrical resistivity method from the surface. Nevertheless, the acquisition techniques, the array type selection and profile(s) deployment are equally influencing the survey results. The relations between the mentioned factors were subject to detailed analysis by constructing various synthetic model...
