The moisture content has a major influence on the efficiency of biodegradation. The efficiency of this technique is mainly controlled by a homogeneous distribution of the moisture content in waste body. Therefore measuring water content in waste landfills is a key issue (Imhoff et al. 2007). Most of studies have shown that surface Electrical Resistivity Tomography (ERT) can be a suitable method to study water content variation (2D and 3D) at a large scale (Guerin et al. 2004, Moreau et al. 2007, Clément et al. 2010) and it is becoming a common tool to study recirculation events in waste landfills. Nevertheless, electrical resistivity is influenced by many physical and chemical parameters and no single relationship with volumetric water content was yet established for municipal solid waste (MSW).The aim of this study was to evaluate the effect of temperature, density and water content on electrical resistivity of waste samples in laboratory.
