The buried palaeo-channel of the Wainganga River was first recognised during preliminary investigations for an earth dam. The buried valley is located about 4.7 km southwest of the present river. As the construction of the dam could affect the hydrogeological balance downstream, investigations were undertaken to assess the re-chargeability of the area. In the absence of any surface signatures, geophysical methods comprising electrical resistivity profiling, and gravity and seismic refraction methods were used to detect the alignment and geometry of the palaeo-channel. The results were consistent with the available borehole data, and the aerial photographs confirmed that the combination of these techniques provided a cost-effective, non-intrusive investigation method for delineating the course of the buried river valley.
