Electrical Resistivity Imaging for Characterizing the Shallow Landslide Hazard Site at Kutupalong Rohingya Refugee Camps of Ukhiya, Cox's Bazar, Bangladesh

Electrical imaging survey technique is especially suitable for shallow site investigations where understanding the complexities of the subsurface structure in detail is important. This study has been carried out to identify subsurface lithological variation by showing a connection between resistivity data and basic geotechnical parameters. The Wenner arrangement of approximately 25 m and 50 m image lines with electrode spacing of 1 m and 2 m respectively have been carried out to collect the resistivity data. The changes of shallow subsurface geo-electric layers are unfolded using RES2DINV software by creating the electrical images for a site located in the Kutupalong Rohingya Refugee Camps area in Ukhiya-Teknaf, Cox's Bazar, Bangladesh. Fundamental geotechnical parameters of the soils of the Kutupalong Site including moisture content, particle size distribution, liquid limit, plastic limit, plasticity index, and specific gravity values were evaluated. The importance of the electrical resistivity values was validated by comparing these geotechnical characteristics with the generated electrical images. As a result, the apparent resistivity pseudo sections give a very approximate but nevertheless useful picture that is illustrated on the image lines revealing subsurface geological changes and support to improve shallow landslide site characterization, in addition to the existing geotechnical site characterization method.
