Groundwater flow after heavy rain in landslide-slope area from 2-D inversion of resistivity monitoring data

摘要

In the interest of monitoring he low of groundwa- ter from heavy rains, we conducted surface resistivity tomography through the vadose zone over several days. The measured data were modeled by 2-D inversion. A Laboratory experiment was carried out to estimate the Difference in geological characteristics. We measured the Effects of ground water fluctuation using two tank mod- Els: one using sand and one using bricks, which rpre- Sent unconsolidated sediments and jointed rocks, respec- Tively. In the sand model, we succeeded in monitoring Water-level fluctuation as the change in resistivity over Time.
