| | Abstract | | We measured resistivity in a laboratory setting fill model and in a landfill to make clear the water path. The paper covers the results of the laboratory experiment. We prepared a simulated fills consisting mainly of incinerator ash in a rectangular tank. The resistivity prospecting method was applied to the fills. The following is the main results of this study. (1) We poured water into the simulated landfills and measured resistivity repeatedly at ten minute intervals. Three dimensional inverse analysis was applied to the apparent resistivity data and 3-D profiles were obtained. Differential profiles were also calculated. As a result, we could detect that the decreasing zone of resistivity was expanding concentrically. (2) We took some undisturbed core samples from the fills and measured the hydraulic conductivity. The zone that changes remarkably in resistivity has relatively high water permeability.From these results, we can visualize the water path clearly using resistivity measurement. |
