Özet

In this paper, I suggest to use combined inversion of three-and four-electrode arrays data. Two-dimensional (2D) inversion results of Wenner (W), Schlumberger (S), Dipol-Dipol (DD), left-and right side poledipole (PD-L and PD-R) synthetic data and their combined inversion results are compared according to resolution and accuracy of the inverted models. Comparison results show that combined inversion of any two arrays data (eg. W+S, W+DD, PD-L+ DD) sets give better resolution than the individual inversion of each corresponding arrays data set. However, inversion of PD-L, PD-R and and DD data sets jointly give better accuracy than the single use of any of these electrode arrays and combined inversion of any two electrode arrays.
