On behalf of the agricultural usage, a resistivity survey of Guryongri region, Chongyang, has been carried out to understand groundwater system. The bedrock, which is composed of the Precambrian gneiss or schist, is covered by the Quaternary alluvium of 20 m thickness.
The Keumkangcheon is interpreted as a possible fault.
The subsurface basin of the bedrock relief is small and driven to the Keumkangcheon through 2 or 3 passages.
Therefore, the subsurface dam is not recommended, whereas the pumping wells are favored.
