Detection of A Possible Subsurface Water Seepage Using 2D Electrical Resistivity Imaging Survey at a site in Al-Khwarizmi College of Engineering, University of Baghdad, Iraq

Unknown subsurface leaking water sources and possible seepage from a sewage tank in garden at Al-Khawarizmi engineering college, University of Baghdad, were detected this study. The 2D electrical resistivity imaging. ERI survey is carried out along two lines, 60m 50m long, with an electrode spacing 1 m, forming cross using the Wenner-Schlumberger array configuration. Line 60m, while line 2 50m. Soil samples collected positions 34, which shows high value, 55, low resistivity, for laboratory analysis. Robust inversion modelling processes showed relative change contrast interpreted resistivities. analysis general homogeneity mineral content sediment type. Therefore, relatively was related to variations content. caused due tank, precisely located.
