Abstract

The survey compares the three common arrays using in 2D imaging surveys, Wenner, Wenner-Schlumberger and Dipole-dipole electrode arrays, and most suitable array is chosen in Uruk archaeological site. The Comparison consist of the resolution and efficiency of 2D resistivity imaging survey with these arrays. Three survey tests on a selected profile in Uruk archaeological site are done to examine the imaging capabilities of these arrays.The survey shows that the Dipole-dipole array has better horizontal data coverage than the Wenner. The horizontal data coverage for the Wenner-Schlumberger array is slightly wider than Wenner array but narrower than that obtained with the Dipole-dipole array. Also, the survey time for survey Dipole-dipole array longer than the others, then that for Wenner- Schlumberger, then at the later that for Wenner array. The survey shows that the Dipole-dipole array has a shallower depth of investigation compared to the Wenner and Wenner –Schlumberger arrays.Finally, it shows that Dipole-dipole array gives the highest resolution and best image for vertical anomalies. During the 2D resistivity imaging in Uruk, Dipole- dipole array is found to be the best array compared to Wenner and Wenner- Schlumberger arrays for detecting archaeological targets.
