When an intake or an outfall of a shallow buried groundwater conduit exists, it is a simple, direct and fast way to trace its direction with the mise-a-la-masse method, even though the charging current position is needed. The self-potential method is good at buried underground flow prospecting, but with too much noise and low resolution. It is wise to introduce shallow seismic reflection method to the exploration of buried groundwater conduits controlled by faults. With prospecting examples, this paper shows how the optimum combination of prospecting methods is selected in the detecting of groundwater conduits and defining of the anomalous features and spatial distributions in different geological conditions and prospecting costs.
