Direct current method is a kind of electrical exploration method. Its common feature is to study the distribution characteristics and laws of DC electric field related to geological bodies for prospecting and solving some geological problems. The field sources used by DC method are artificial and natural. The differences of electrical properties used include the differences of resistivity and polarizability of rocks and ores


The theoretical basis of the electric method to find water is scientific, because the resistivity reflects the conductivity of underground rock, so the resistivity value we get just reflects the electrical property of the rock, so that we can find the accurate water level. After the water level is found, the burial depth of the water level can be obtained by applying the sounding method above the water level, and the trend and tendency of the water-bearing structure can be obtained according to multiple sounding points. Therefore, the accuracy of the electric method is high, which is incomparable with other geological methods.
