| | Abstract | | In order to investigate long-term water behavior in waste layers, we have conducted model experiments by using time-lapse 3-D electrical resistivity tomography. Eighty one electrodes for resistivity measurements were installed on the container filled with sand and clay or wastes and clay. The size of container is 185cm high, 150cm wide and 75cm deep. Three dimensional measurements were carried out repeatedly during several months. The results of 3-D analysis of these data show that observed resistivity change was well consistent with moisture content according to water supply and drainage, and with the range of infiltrating salty water. Resistivity increase of waste layer due to rinse effect is also recognized. |
