Integrated geophysical and geotechnical analyses at a landslide area - Case history in Lopare, Bosnia and Herzegovina

Abstract

© 2019 24th European Meeting of Environmental and Engineering Geophysics. All rights reserved. A heavy rainfall in May 2014 caused an extensive damage in the Balkan area. A combination of seismic reflection, MASW and electric resitivity surveys are carried out to supplement a surface geotechnical observation at an area in Bosnia and Herzegovina for potential of further landslides. This is a Geoscientists without Borders project. Surface observation found soft and low strength layers in the area with multiple scarps and cracks. The depths of slip surface are estimated at 10m at the upper part of slope and about 2m at the lower part of slope. These are indicated by low reflectivity on the seismic reflection, low S-wave velocity in the MASW and high conductivity in the resistivity tomography sections. According to these results, several suggestions are made to local government to mitigate landslide disasters.
