Enhanced-Power Ground Penetrating Radar Survey and Electrical Resistivity Tomography of Geological-Engineering Structure for Groundwater Filtration Zone Research

Summary Carried out enhanced-power ground penetrating radar (EPGPR) survey and electrical resistivity tomography (ERT) of geological-engineering structure for groundwater filtration zone research by Vilyuiskaya GRE and Yakutniproalmaz Institute. It used EPGPR Loza-2N and the ERT apparatus Skala-48. Measurements by a highfrequency electromagnetic field and measurements by direct current were made in different seasons, in winter and summer, respectively. The survey results are compared with the available observation wells. There is a well similarity of the survey results by two methods, and consistent with a priori information.
