The application of half decay time parameter of IP to exploration of underground water in the hilly area
Applying IP sounding method to the exploration of underground water in the villages of water shortage in hilly areas of Dongping,the authors made an integrated analysis of the half decay parameter Stso as to accurately determine the location of the groundwater-bearing structure and the depth of the water-rich strata. The study was in combination with regional hydrogeological conditions and on the basis of the IP parameters,i. e.,apparent resistivity ρsand polarization rate ηs. Drilling verification shows that the water inflow of per well is more than 60 m3/h,thus solving the difficulties in the water supply for local production and people's livelihood. This study has accumulated experience for underground water exploration in similar regions in the future.
