Brine seepage tracing in a damaged dam slope using elapsed-time electrical resistivity tomography

The electrical resistivity tomography technique is a geophysical inspection method widely used for several investigations, such as mining exploration, fault localization, groundwater flow, geological and pollution zones. Infusing brine into substructure can increase conductivity becomes useful medium to trace the path of seepage flowing in rockfill dams. In this article, an elapsed-time was developed monitor potential damaged dam slopes nearby concrete spillway. Tracing downhole could effectively identify possible direction through mass few hours. spatial distribution variations images also provide information about sliding surface accumulation zones downstream side slope dam.
