A direct current is sent to the earth, and the current is shut off. The difference between transient potential and the potential of immediatly before breaking contact is measure, and the ratio is shown in percentage. Thus the distribution of chargeability is gotten. The minimum chargeability shows a boundary of strata, a large dielectric constant shows the layer of subterranean water. The maximum shows the upper limit and the minimum the lower limit of the water layer. It is reported that the investigations are classified as three typical kinds mentioned below. 1. The investigation of the subterranean water in Alluvial Epoch stratum. 2. The investigation of the subterranean water in Tertiary Period stratum. 3. The investigation of the cavern water in limestone. The result of the investigations shows that a large chargeability is observed at the subterranean water layer in each stratum.
