Abstract
High-density electrical prospecting was conducted on a heightened earthfill darn during the first filling of the reservoir to study the possibility of applying this prospecting method to examination of zoned structures inside an embankment darn and monitoring of seepage through the dam body. Visual Inspection and measurement with the measuring devices were also conducted to control the safety of the dam. As a result, it was found that zoned structures inside the dam such as a newly built embankment, an existing embankment, and drain are zones each having a different resistivity value. In addition, since the area where the resistivity inside the darn body changed with the impounding almost coincided with the area where pore water pressure changed, the seepage area is an area where the resistivity changed.

Survey of Seepage Through Heightened Earthfill Dam With High-density Electrical Prospecting Method
St. Louis, Missouri
