A few engineering geology and geotechnical case studies are seen in this research paper that are solved using two dimensional (2D) electrical imaging surveys (ERT) and, in four cases, ground penetrating radar (GPR). Case studies that demonstrate the versatility of the ERT method as well as other methods that complement obtained ERT data will be presented. Surveys of flotation tailings, detection of old mines, communal waste dumps, rock quality and lakebed surveys, and so on are among the case
