In this paper, we present integration of remote sensing, GIS, GPR and ERT techniques to detect underground qanats at Shahid Bahonar University of Kerman, Iran. These studies were defined because of the subsidence problems and cracks of some building walls at the main campus of the university due to unknown hidden qanats. The results of remote sensing studies tracked eight qanat systems passing under the university campus. These results were validated by field visits. GPR studies performed up to now in some parts of the campus showed the depth of qanat systems to vary in the range of 8-15m. Detailed geophysical surveys including GPR and ERT measurements are still to be completed with the aim to reconstruct the maps of underground qanat galleries. Our results and observations have inspired the new idea to construct a geotechnical-geophysical test site of natural qanats at the university main campus. We propose an area in the southeastern part of the university that is not likely to be significantly included in the future construction plans and it also hosts a sequence of non-collapsed shafts which can be used to better evaluate the site.

Abstract

In this paper, we present integration of remote sensing, GIS, GPR and ERT techniques to detect underground qanats at Shahid Bahonar University of Kerman, Iran. These studies were defined because of the subsidence problems and cracks of some building walls at the main campus of the university due to unknown hidden qanats. The results of remote sensing studies tracked eight qanat systems passing under the university campus. These results were validated by field visits. GPR studies performed up to now in some parts of the campus showed the depth of qanat systems to vary in the range of 8-15m. Detailed geophysical surveys including GPR and ERT measurements are still to be completed with the aim to reconstruct the maps of underground qanat galleries. Our results and observations have inspired the new idea to construct a geotechnical-geophysical test site of natural qanats at the university main campus. We propose an area in the southeastern part of the university that is not likely to be significantly included in the future construction plans and it also hosts a sequence of non-collapsed shafts which can be used to better evaluate the site.
