A total of 456 line-meters of radar profiles were acquired. The GWS produces relatively strong reflections and distinct images in all the radargrams acquired within the survey site. The variation in the depth to the groundwater surface measured at the borehole point and the GPR measurement at the same location were is close agreement. The high degree of correlation in the estimated values obtained from the radar profiles and the actual values obtained in the borehole indicated that GPR is capable of defining accurately the GWS.
