| | Abstract | | The electrical prospecting system with scanner can be controlled by the personal computer. This made it easy to measure the resistivity change of the ground using the time-laps method. However, it took a lot of time to perform two-dimensional inverse analysis on the data measured in large amounts. In order to solve this problem, we examined what the apparent resistivity change ratio cross section represents. As a result, it was found that the apparent resistivity change ratio cross section and the resistivity change rate cross section show almost the same change in the resistivity of the ground. By using the apparent resistivity change rate cross section, it became possible to save a lot of time. |
