Abstract

This research discusses the exploitation of Dar-Zarrouk (D-Z) parameters which
were deduced from the quantitative interpretation of 80 Schlumberger Vertical
Electrical Sounding VES points distributed in six profiles within the Sinjar plain
area which bounded by the coordinates:Latitudes :35P

Iraqi general commission of groundwater. The VES field readings were interpreted
manually by applying the (auxiliary point -partial resistivity curve matching)
method, then the interpretation enhanced by using sophisticated computer software.
The VES field data were interpreted and analyzed with an advanced technique
through the deduction of D-Z geoelectric parameters which are: Longitudinal unit
conductance (S) and Transverse resistance (T), then a new geoelectric maps were
constructed. The D-Z parameters maps were used to differentiate aquifers of fresh
groundwater from those of saline ones. This technique reduced the ambiguity related
to interpretation which mainly produced by principles of equivalence and
suppression and cause intermixing in recognizing depth limits for the electrical
zones (fresh and saline water bearing formations) during interpretation. The drawing
of (D-Z) and other geoelectric parameters maps provided a decipherable vision
about the occurrence and distribution of saline and fresh groundwater aquifers
within the study area.
