To understand water content distribution in waste landfills consecutive to leachate recirculation, resistivity tomography surveys begin to be used. To study the relationship between these physical variables, laboratory tests are performed on 200dm3 fresh and recomposed wastes samples. To simulate landfills conditions, large bulk density range (0.28 to 0.67), water content range (0.20 to 0.75 m3/m3) and temperature range (20 to 55°C) are explored. Results confirm a good sensibility of the method and highlight a large anisotropy (ratio  4) between vertical and transversal resistivity measurements in our samples. Relationships obtained with vertical resistivities data can be fitted on Archie-law for volumetric water content lower than 0.5 m3/m3. Bulk density effect is important for vertical resistivity (about 0.1 m3/m3 for 0.35 m3/m3 medium water content value). For lateral resistivites data, a global fitting is nevertheless possible with RMSE not higher than 0.078 m3/m3. Temperature effect is major (mean 4.3 .m/°C) and a hysteresis phenomenon is observed.
