      Without any searching I say dig it to find it. I did the google search and there are several ways including magnetic resonance imaging, ground penetrating radar (GPR) and many more. There are also local knowledge from people who need to find groundwater such as a forked twig by a dowser in Burkina Faso. Check it out!
