Geophysical Expression of Natural Recharge in Different Geological Terrains

Behavior of the Dar‐Zarrouk parameters—longitudinal unit conductance, transverse unit resistance, longitudinal resistivity, and transverse resistivity—has been compared with the behavior of the natural recharge in two geological terrains. Contour patterns of the geophysical parameters and those of natural recharge have been analyzed and a qualitative relation in their behavior was recognized. Graphical comparison of the geophysical and hydrogeological parameters clearly illustrates a qualitative relationship between the two parameters. Use of such qualitative relation in the field of ground water exploration and management studies is explained. A modest beginning is attempted to arrive at a quantitative relation between natural recharge and Dar‐Zarrouk parameters.
