Traditional methods of siting boreholes
- Siting by the driller
- Water divining
- Siting by a hydrogeologist or water engineer, having studied the local geology, geomorphology and satellite imagery
- Geoground physicall survey – usually some form of electromagnetic depth surroundings to determine the variation of electrical conductivity with depth or seismic refraction to identify paleo-channels.
