Many years of practical application of non-classical geoelectric methods of forming a short-pulsed field (FSPEF) and vertical electric-resonance sounding (VERS) in the near-surface geophysics problem solving have demonstrated their high efficiency in searching and delineating subsurface water flows and aquifers. The results of our study indicate that the zone of rocks moistening, underground water streams of natural and man-caused origin and aquifers are detected and mapped operatively by areal survey with FSPEF method. The depth of lying and thicknesses of water-saturated horizons are determined with a high accuracy by VERS sounding. Field works of such type are often executed very quickly and easily. The FSPEF and VERS methods make a significant contribution into emergence of a new paradigm of geophysical research, which includes the “direct” searching for a specific physical substance: gas, oil, gas hydrates, water, ore minerals and rocks (gold, platinum, silver, zinc, uranium, diamonds, kimberlites, etc.). The effectiveness of these geophysical methods based on the paradigm principles is much higher than that of traditional ones.
