Abstract
Electrical prospecting method is traditionally used to obtain an information of geological profile, as one of geophysical prospecting methods for hydrogeological survey. However, recently, we need to develop a new technique which provides a moving profile of resistivity due to the groundwater flow.
A new technique, in which movement of an electrolyte tracer is obtained by means of resistivity measurements and the feature of the tracer movement beneath a survey line is visually displayed, is demonstrated in this paper. Sodium chloride is used as a tracer. The effectiveness of this method is ensured with the result of borehole loggings.
