| | Abstract | | We measured resistivity in an experimental tank and in a landfill, in order to make clear the water path in fills. This paper covers their results. We prepared a simulated fills consisting mainly of incinerator ash in a rectangular tank. We poured water into the simulated fills and measured resistivity repeatedly at 15 to 20 minutes intervals. Three dimensional inverse analysis was applied to the apparent resistivity data and 3-D profiles were obtained. Differential profiles were calculated by using the method of Difference inversion. As a result, it was clarified that the decreasing zone of resistivity was expanding concentrically and the rate of resistivity change was increasing as water poured. Furthermore, the above methods were applied for the landfills and their results were also examined. |
