The dowsing model is that water travels in narrow underground streams which one's well must hit dead on or be dry.
Yes. But I was early aware of the more accurate French terminology which talks of 'layers'- 'nappes phréatiques'. Where I live we are on hilly London clay, in a Victorian inner suburb (East Dulwich) which is riddled with sewers and channeled streams- one runs fast and continuously under our front garden, a few metres down, and our coal cellar floods regularly but harmlessly at curiously random seeming intervals, to a depth of a few centimetres. The 'professional' dowsers I read about had been used to find underground pipes, features of that kind. A great deal of that kind of thing goes on in our local streets, but they seem to use ground penetrating radar and exploratory trenches. Sometimes they inject dye, ro see what's connected to what. The water in our cellar, normally clear, had a season of being black (or deep blue). Seems to have reverted to clear... It's not from a broken sewer, as it's totally free of any smell.
As you say, not terribly AR, but it really does bring Titty to mind when I see them at work.
