Research Abstract

For the purpose of physical evaluations of critical rainfall for triggering landslides, we constructed a new method to detect preferential water flow pathways developed in natural hillslopes. The method combine the electrical resistivity measurements with the measurements using the newly-developed CPMP (combined penetrometer moisture probe). By using this method, we clarified rain water dynamics around the preferential water flow pathways.
