الملخص الانجليزي
Electrical resistivity techniques are considered to be the most applicable for geological, geotechnical, environmental and archeological studies. The use of 2D and 3D resistivity surveys has enabled us to mapping complex geological, detecting cavities, walls and other man-made structures that were not previously possible with conventional 1D resistivity surveys. ABEM Terrameter LS was used for data collection. The fieldwork was conducted in Ministry of Since and Technology, Baghdad, Iraq. The survey design is based on choosing the electrode configuration taking into account available information about the site and the advantages of the ERI technique.2D electrical resistivity and IP imaging sections have been obtained. The data analysis comprises of 2D inversions using the RES2DINV software. The obtained data analyzed, and 2D models of the subsurface was generated.For the fieldwork, two-dimensional surveying was carried out along two profiles using Wenner and Dipole-Dipole arrays with length of 40 m and electrode spacing 1. The max depth of penetration is ranged between 6 to 7 m.The IP values for the field site are ranging from (-2 to 18) mV/V with good agreement with resistivity data, where high chargeability are associated with low resistivity.
