Contribution of electrical resistivity tomography applied to the slope deformation survey in Lidečko

Abstract

In the last years, electrical resistivity tomography (ERT) has been increasingly used to solve various types of problems in engineering geological survey, geotechnical investigations, etc. It gradually replaces a traditional combination of methods of resistivity profiling (RP) and vertical electrical sounding (VES). This paper provides selected results obtained from the survey of a slope deformation in Lidečko. It brings also some new details about its construction and results of monitoring carried out in the year 2011. The largest landslide hazards result from its position over a water pipeline line, where there is a real risk of a massive landslide of the slope ending in the valley of the Senice River. It is an old landslide reactivated during the floods in the years 1997 and 2006.
