Research Abstract

Groundwater flowing through fracture zone with high rate often becomes the principal cause of material transfer and slope disaster. Landslides and earthquakes promote loosening of the ground with fractures and increase infiltration. The sonde system was developed to measure groundwater potential and water sampling at arbitrary depth in all-strainer type boreholes. Groundwater potential monitoring was conducted in snow melting season in upper area of Shimekake Landslide. Increase in groundwater pressure due to big earthquakes was observed in Tateshita Landslide.
