영문 초록

A set of geophysical survey results over an area in Bookil-myun, Chungwon-Gun, Chengcheong-buk-Do is presented; resistivity logging, d.c. sounding, dipole-dipole resistivity, and controlled-sorce magnetotelluric (CSMT) surveys. These surveys were chosem in this research for the estimation of the basement depth and the delineation of the hydrogeologic srtucture over the survey area. The results provide an optiomal input to a hydrogeologic medeling analysis usinf the strategies built in GIS softwater. A total of 14 lines of dipole-dipole resistivity surveys, 25 stations of D.C sounding and 6 stations of CSMT sounding were performed. In addition 10 boreholes were chosen for resistiveity logging to correlate the logs to the surface data. A quantitative information on the hydrogeologic structure over the are is provided by synthesizing the results from various geophysical data and attribute layers are constructed by utilizing a GIS software Arc/Info. The constructed layers match well to the hydrogeologic structures, which were outlined from the drilling data. The methodology tested and adopted in this study would be useful for providing a more reliable input to the hydrogeologic model setup.
