Abstract GPR is a non-destructive method based on the emission and reception of electromagnetic waves generated by a bowtie antenna, of 400 MHz, in our case. The soil conductivity influences the propagation of electromagnetic waves, thus any inhomogeneity as water lens, chemical pollution, soil texture, buried objects modify the signal scattered on them and recorded by GPR tools. One of the potential advantages of GPR is that it is able to quickly analyses the presence in the underground of various inhomogeneities without having to come into contact with the ground and measures the time interval between pulse generation and reception, the results being presented in B-scan and linescan representation. Combining and processing the received signals, the results show as a map with emphasized watering regions. This paper presents the results of a case study where it was determined the effectiveness of GPR technology in detecting water content as well as the presence of water holes in airport runway draw. Further investigations will include the use of GPR together with electromagnetic induction method in order to make data fusion and increase the probability of detection.
