Applying GPR and 2D ERT for shallow landslides characterization: A case study

Abstract

We present a procedure to estimate the characteristics of small shallow landslides based on the application of ground penetrating radar (GPR) and 2D electrical resistivity tomography (ERT). Existing procedures based on either conventional or non-invasive geophysical methods, observe almost exclusively large and deep landslides. Verification has been done on a small shallow landslide in the village of Vinča, near Belgrade, Serbia. The proposed procedure is realized in two simultaneous steps. First, from high resolution raw data obtained by GPR survey, soil horizons inside and near landslide body are estimated up to 4 m deep. The rupture surface is defined and its depth is estimated at 1.7 m. Second, ERT technology confirmed and integrated the results obtained by GPR survey. Main advantages of proposed procedure are efficiency and applicability for small shallow landslides whose number and impact on environment is dominant. © Springer-Verlag Berlin Heidelberg 2013.
