Application of geophysical methods to investigation of old castle, especially of the moat; Joshi no chosa ni okeru butsuri tansa no tekiyo (horiato no tansa)

Abstract

An explanation is made about the application of geophysical methods to the investigation of the ruins of old castles especially of their moats. Techniques currently in use for exploration of the ruins of castles are mainly underground radar exploration and electric exploration. The underground radar method sends electromagnetic waves through the ground and receives the reflection for a high-precision exploration of the layers shallow in the ground. Therefore, this method is suitable for probing the ruins of castles relatively shallow in the flat land, hills, and mountains. The electric method (resistivity image method) do the probing by use of the two-electrode arrangement, performs inverse analysis on the basis of the obtained data for the determination of the underground resistivity distribution, and displays the distribution in an image easy to read. This method, when there is a great separation between the two electrodes, explores relatively deep into the ground. Thanks to this feature, this method is effective in probing relatively wide and deep ruins of moats, that is, the ruins of moats of castles built in later years, especially of those then filled with water. 2 refs., 5 figs.
