I am doing a research project at school on erosion, and one of the members on my research team said something about underground tiles that run water into the nearest body of water. We have been trying to locate a source, or ANY piece of information on this subject, but have failed. Is there anyone who can help us?
These aren't erosion tiles, they are drainage tiles. Do a web search on tile drainage and you'll find out all you need to know about the subject. BTW, tiles and tile lines are just underground pipes with holes in them, used to lower shallow water tables. It wasn't clear to me that you understood this, so sorry if I'm pointing out the obvious.
