Abstract
We are presenting in this paper the relative distributions<br>of horizontal and vertical components of current<br>density in a vertical section of synthetic aquifer<br>simulating different geoelectrical settings. These<br>computations are made using a recently derived general<br>equation for potential field due to a direct current<br>source arbitrarily located in a non-uniform layered<br>medium. On the basis of comparative analysis of<br>computed data we conclude that in case of fresh water<br>saturation, the horizontal current density within the<br>aquifer is greater than the vertical component, for a<br>substratum of resistive nature, and vice-versa for a<br>substratum of conductive nature.
