Abstract: As granite regions are generally short of groundwater, it is relatively difficult to find water, and the results of using a single geophysical method are often unsatisfactory. In recent years, through a series of 1:50000 hydrogeological surveys, the integrated electrical method is used to determine several well locations in granite regions, which all have obtained satisfactory results. Two examples of locating wells are selected to analyze the electrical characteristics of the high-density electrical profile and IP sounding curve in the relatively water-rich granite regions. The practices prove that the combination of high-density electrical method and IP method can improve the efficiency and accuracy for locating wells, and can also be used as reference for water prospecting in similar strata.
