and 3D resistivity imaging methods are simple, fast,
inexpensive, and relatively accurate techniques used in
geophysics exploration. In this study, 2D and 3D resistivity
imaging methods are used to produce images of the subsurface
structure of the University of Technology in Baghdad, Iraq.
Three 2D images are utilized to create a 3D slice image and
a 3D block image for three conventional arrays. Each 2D
image has a length of 60m and a depth of approximately 12m,
and the spacing between lines is 1.5m. Results show that the
study area consists of two types of material: sandy gravel
and clay. The borehole data obtained near the study area are
used to confirm the results. The 2D and 3D images, as well
as the three conventional arrays, are compared. Wenner array
is found to be the most suitable array for 2D and 3D imaging
of the study area.
