Abstract: Fengquan district in Xinxiang is one of the areas in China characterized by shortage of groundwater resources. To tackle this situation, the authors applied the combination of high density resistivity method, EH-4 conductivity sounding and induced polarization of symmetrical quadrupole to groundwater resources prospecting in loose rock and bedrock regions, and achieved remarkable results un-der complex hydrogeology conditions. The experience gained by using the combination mode of different electrical methods for water prospecting under different hydrogeological conditions was summed up in this paper. The application of combined mode provides reliable and scientific basis for determining location of well in the process of groundwater prospecting, and also guarantees high success rate in well drilling. -
