Fountains of Permaculture Water

Paul posted an idea here, a while back, about drawing the water table/a river up the slope, using trees. Where I can find that information?
I live on a bluff, 1100 feet. I understand how to capture runoff, my dream is to strategically plant trees to draw the water up to a specific area to make it wetter and/or create a stream. I imagine the tree sucking the water up through a straw.
