Abstract:

 A ground-penetrating radar survey was conducted at the eastern part of the University of Baghdad Campus to detect buried engineering objects and evaluate the lateral soil heterogeneity in the site. Malå Geoscience RAMAC system equipped with a 250 MHz antenna was used to perform the survey. Four profiles with a length ranging from 30 to 46 m were acquired across the site. Two parallel profiles were oriented in the N- S direction, while other two profiles were oriented E-W, to provide adequate spatial coverage. The collected data were processed and interpreted using Reflex-Win software following standard processing procedures. In profiles A and B, a prominent hyperbolic anomaly was identified at approximately 14 m along them at depth of 1.0 m. Another hyperbolic shape is detected in profile A at distance 24m, depth of 1.6 m. Having profile C, two hyperbolic reflections were observed, the first was located at a distance of 2 m, depth of 1.4 m, whereas the second one located at approximately 22m with a depth of about 0.8m. The radargram of profile D exhibited three distinct hyperbolic anomalies located at distances of 1m, 12m, and 32m, with corresponding depths of approximately 1.4m, 1m, and 1.4m, respectively. In addition, shallow subsurface variations were observed at depths ranging from 0.5 to 0.8 m, which may indicate variations in soil compaction or the presence of fill material across the surveyed section. Some surface noise was also detected, extended into the deeper part of the radar sections, particularly beneath the concrete slab which identified in profiles A and D.These findings were validated by comparing them with the engineering layouts of the University of Baghdad Campus, which confirmed that the detected anomalies correspond to the locations of underground high-voltage electrical cables and water pipes. Overall, the results demonstrate that ground penetrating radar is an effective non-destructive geophysical method for detecting buried engineering and characterizing of shallow subsurface conditions in the urban environments.
