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.
