| Popis: | Subsurface structures from two different districts of Istanbul, hosting waste and freshwater transmission lines, were imaged by geoelectrical method. The environmental impact on Kagithane-Terkos freshwater transmission line is one of the issues. That waterline underwent a substantial landslide damage. The previous site selection of Kagithane-Terkos line was only based on surface geological observations. Even though the pipeline was positioned away from the surface scarps of landslides, the pipes were damaged. To find out the reason, we made some vertical electrical sounding measurements using Schlumberger array in the region. We inverted the electrical sounding data using 2D inversion technique. The final geoelectrical images show main landslide failures, at about 10–30 m depth, which are overlain by debris with a resistivity value of with |
