This study was conducted in the dangerous slopes for deep-seated landslide existing in the Migi-Aizu River basin in the Tanabe City, Wakayama Prefecture. And focusing on the electric conductivity of the spring water after a rainfall and spring water flow rate and discharge rate of the tank model,examined the measurement criterion for the dangerous slopes for deep-seated landslide. From discharge rate of the tank model after rainfall as a result electric conductivity revealed about the observation period.
In result, the EC of spring water will change under the influence of rainfall,between the EC of spring water and the total tank volume have high relevance, the influence of rain continues longer than the EC of spring water in the tank outflow amount.
