Geophysical studies for landslide investigation in Imamzadeh Hashem - Roodehen gas pipeline path,Tehran province

This paper deals with geophysical studies using three methods of 1D geoelectrical method, 2D IP&RS geoelectrical method (using polar-bipolar arrangement) and also GPR method on the line passing through Imamzadeh Hashem-Roodehen located in Tehran province to investigate the causes of landslides.

For this purpose, in the study area, 20 irregular electrical soundings along 10 profiles and 2 electrical profiles with polar-bipolar arrangement with different azimuths with the length of 190 meters were surveyed by IP-RS method with station distances of 5 and 10 meters and also GPR method in 1000 meters.
