Underground Temperature Survey in and around the Landslide Area -1- (A New Investigation Method of Underground Water)

Abstract

It has been clarified by the existing investigated results that the underground water was existent as the vein-stream in and around the landslide area. Therefore, it was very difficult to obtain the informations concerned with location of the vein-stream of underground water by using various kinds of tracer methods. As it would be preferable to assume the location of the vein-stream before carring out the existing tracer methods and conduct the survey, the author tried the underground temperature survey which had been utilized at the hot-spring in order to presume the location of the underground water vein-stream. Excellent results were obtained by this survey method.
